                        TUESDAY, MARCH 12, 2024

                              United States Senate,
                               Committee on Armed Services,
                                                    Washington, DC.
    The Committee met, pursuant to notice, at 9:30 a.m. in room 
SH-216, Hart Senate Office Building, Senator Jack Reed 
(Chairman of the Committee) presiding.
    Committee Members present: Senators Reed, Gillibrand, 
Blumenthal, Hirono, Kaine, King, Peters, Kelly, Wicker, 
Fischer, Cotton, Ernst, Scott, and Schmitt.

             OPENING STATEMENT OF SENATOR JACK REED

    Chairman Reed. Good morning. The Committee meets today to 
discuss a range of global security challenges to the United 
States. As the Biden administration's National Defense Strategy 
(NDS) has made clear, we are in a long-term strategic 
competition with China and Russia. Ultimately, this competition 
is not just a rivalry of military or economic power but also a 
competition of ideas. This requires us to develop an 
understanding of our potential adversaries' strengths, 
weaknesses, philosophies, and objectives. This is where the 
knowledge and insights of the experts before us today are so 
valuable.
    Dr. Paul Scharre is the Executive Vice President and 
Director of Studies at the Center for a New American Security. 
He is an expert on the future of technology and warfare, 
particularly with regard to artificial intelligence (AI) and 
autonomous weaponry, and has authored several influential books 
on these issues. Dr. Scharre worked previously as a policy 
expert in the Department of Defense (DOD) and served as an Army 
Ranger with multiple combat tours. Thank you.
    Dr. Hal Brands is a Senior Fellow at the American 
Enterprise Institute and serves as the Henry Kissinger 
Distinguished Professor of Global Affairs at the Johns Hopkins 
School of Advanced International Studies. He worked previously 
as Special Assistant to the Secretary of Defense for Strategic 
Planning and was a lead writer for the 2018 National Defense 
Strategy Commission. He has authored several books on U.S. 
grand strategy and statecraft.
    Thank you both for joining us today and for your long 
careers of service to the Nation.
    Our objective today is to examine the national security 
issues that this Committee should consider as we prepare the 
Fiscal Year 2025 National Defense Authorization Act. There is a 
common understanding on the Committee that the future of 
America's national security is tied to our competition with 
China. To keep pace and maintain America's edge, the Department 
of Defense must understand China's competitive tactics, develop 
new competitive tools of its own, and integrate with our allies 
and partners.
    For several decades, the People's Liberation Army (PLA) has 
studied America's way of war and focused its efforts on 
covering our advantages. China has invested in offsetting 
technologies like anti-access and aerial denial systems, 
artificial intelligence, unmanned vehicles, hypersonics, and 
nuclear weapons. Further, Beijing has leveraged a combination 
of military and civil power against its neighbors, include 
statecraft, economic pressure, coercion, and deception. China 
has sought ways to achieve its national objectives while 
avoiding a direct military confrontation with the United States 
military. As the Defense Department's new Joint Concept for 
Competing states, China seeks to win without fighting. The 
strategy warns that if we do not adapt our approach, compete 
more effectively, the United States risks ceding strategic 
influence, advantage, and leverage while preparing for war that 
never occurs. Indeed, the document warns that the United States 
could lose without fighting.
    Just as Chinese leaders have studied America's way of war, 
we need to study theirs. With that in mind I would ask our 
witnesses for your assessment of how China is evolving its 
competitive strategies and objectives. I would also appreciate 
your views on what military and non-military factors are mostly 
likely to impact Chinese decisionmaking with respect to 
potential action against Taiwan and other regional partners.
    Even as we chart this long-term competition with China, we 
must recognize the current threat Russia poses. Let's be clear. 
Russia's war against Ukraine is an active threat to our 
national security. Vladimir Putin has repeatedly said that if 
he succeeds in Ukraine he intends to reunify former Soviet 
states. This will almost certainly involve direct military 
conflict with a NATO [North Atlantic Treaty Organization] 
country, requiring the United States to send our own men and 
women into harm's way. We must continue our support for Ukraine 
so we can defeat Putin and cripple his ability to wage war 
elsewhere.
    As we are seeing in Ukraine and the Middle East, the nature 
of conflict and deterrence is evolving quickly. Cyber 
information and space operations can shape the battlefield as 
fundamentally as air, land, and sea power. The interconnected 
nature of these activities must drive the way we develop and 
field new technologies.
    The Defense Department continues to develop the Combined 
Joint All-Domain Command and Control (JADC2), concept, which 
would be a force multiplier in this regard. JADC2 will enable 
the Joint Force to detect, analyze, and act on information 
across the battle space quickly using automation, artificial 
intelligence, and predictive analysis.
    If we can field these technologies and mass these 
techniques then we must quickly include our allies and partners 
in the system. Indeed, forging and maintaining strong 
international partnerships is likely to be the decisive factor 
in any future conflict. We have seen this through Ukraine's 
remarkable performance against Russia, and it will hold true in 
the Indo-Pacific.
    I look forward to our witnesses' testimoneys, and I thank 
them again for their participation.
    Let me now recognize the Ranking Member, Senator Wicker.

               STATEMENT OF SENATOR ROGER WICKER

    Senator Wicker. Thank you, Mr. Chairman. Our Chairman has 
just delivered a rather sobering opening statement.
    Today's witnesses are here to help this Committee take 
stock of changing threats to American interests. They will help 
us reflect on our progress in mitigating and combating those 
threats over the past year or so.
    The scorecard does not look good.
    The Chinese Communist Party (CCP) shows no sign of stopping 
its military modernization project. In fact, China added 30 
ships last year compared to our overall reduction of 2. In 
fact, the People's Liberation Army (PLA) also continues to 
improve its force readiness with complex exercises focused on 
the so-called reunification of China with Taiwan.
    The CCP also continues its regional aggression on other 
countries' sovereign rights. For example, they have repeatedly 
harassed the Philippines' resupply ships in the Second Thomas 
Shoal. Although the San Francisco summit between Presidents 
Biden and Xi produced some feel-good headlines, Xi concluded 
the summit by reminding the United States that he intends to 
control Taiwan, peacefully or not.
    A year ago, we all hoped for significant progress in 
Ukraine's much-awaited offensive. That progress fell short. We 
failed to capitalize on temporary Russian weakness, and now 
face a Vladimir Putin increasingly convinced he can win in 
Ukraine, or at least outlast us and outlast everyone else. 
China, Iran, and North Korea are all contributing to Russia's 
war effort.
    Much has also changed in the past year with Iran. Tehran 
has used the chaos following Hamas' October 7th massacre as an 
opportunity to have its proxies attack United States Forces 
more than 160 times, including with deadly consequences in 
Jordan and in the Red Sea. Iranian-armed Houthis also continue 
to attack critical global maritime commerce in the Red Sea.
    Not to be outdone, North Korea seems to have moved into an 
offensive war preparation mode. This shift from a long-held 
defensive posture is a significant development which further 
complicates the picture in East Asia.
    Worse yet, all four of these adversaries drastically 
deepened their military and economic cooperation over the past 
year, even as we implement a National Defense Strategy that 
largely considers each adversary individually. I struggled to 
use the word ``implement'' because it seems to me that we have 
a strategy that is not being fully attempted.
    I would like to hear from the witnesses how they assess the 
current threats from all of these adversaries.
    The year 2023 was a discouraging year for U.S. national 
security, and 2024 will be worse without substantial investment 
in our military forces. This Committee recently heard about 
challenges across maritime, air, and space domains, as well as 
challenges with insufficient inventories of long-range 
munitions in the Indo-Pacific theater. If we have any hope of 
deterring threats from China, we need to act immediately to 
enhance our capabilities.
    Our needs across the combatant commands and within the 
services are much too long to list here. We need more 
submarines. We need more amphibious ships. We need to give our 
servicemembers more visibility through intelligence, 
surveillance, and reconnaissance tools. We need more torpedoes. 
We need more of the SM-6 multi-role missiles, more of the 
Tomahawk strike missiles our ships and submarines carry, and 
more of the Long-Range Anti-Ship Missiles that allow us to hit 
enemy ships precisely from a safe distance. We need all of 
these things now.
    I welcome our witnesses' suggestions on how to improve the 
Pentagon's ossified planning, contracting, and budgeting 
processes, which continue to prevent us from producing cost-
effective programs on time and at scale.
    I would also be interested in our witnesses' perspective 
about the sufficiency of the overall topline defense budget. 
The budget proposed yesterday by President Biden requests yet 
another significant cut in defense. He proposed this even as 
the Chinese Communist Party announced a 7.2 percent defense 
budget increase just last week. Is it too much to ask that we 
return to the generous portion of GDP [gross domestic product] 
that gave us more than a decade of peace during the Reagan era?
    We continue to ask our military to do too much with too 
little, and that needs to change. I hope this Committee, Mr. 
Chairman, on a bipartisan basis, is prepared to act this year 
to ensure we address this looming national security crisis.
    Thank you, sir.
    Chairman Reed. Thank you very much, Senator Wicker. Dr. 
Scharre, please.

STATEMENT OF PAUL SCHARRE, Ph.D., EXECUTIVE VICE PRESIDENT AND 
     DIRECTOR OF STUDIES CENTER FOR A NEW AMERICAN SECURITY

    Dr. Scharre. Thank you, Chairman Reed, Ranking Member 
Wicker, and distinguished Senators. Thank you for having me 
here today.
    We live in a period of tremendous technological change. 
This creates opportunities for the United States but also for 
our adversaries. The U.S. military must adopt technology faster 
than its competitors. The bulk of technological innovation is 
occurring outside DOD, and DOD must prioritize spinning-in 
commercial technologies and harnessing them for military 
advantage. This contest to rapidly adopt commercial 
technologies is an all-too-level playing field with our 
competitors.
    China also has access to world-class technology companies, 
and the PLA is working to ``intelligentize'' its forces. DOD 
needs significant institutional change to keep pace with the 
speed of technological innovation. Without these changes, we 
risk falling behind competitors and the U.S. military being 
unprepared in a future conflict.
    DOD cannot lead in 21st century technologies with a 20th 
century bureaucracy. The tech innovation landscape has changed 
dramatically in the past half century, but DOD institutions 
have not kept up. It is not merely that the technology itself 
has advanced. That alone would be manageable. The problem is 
that the role that DOD plays in tech innovation has changed, 
but DOD has not yet sufficiently adapted to this new reality.
    The Defense Department used to be the main driver of global 
innovation, but not anymore. In 1960, DOD alone controlled 36 
percent of global R&D (research and development) spending. DOD 
could single-handedly drive the shape of technological 
evolution around the world. DOD could make bets that others had 
to respond to.
    Now today this dynamic has reversed. DOD controls only 3 
percent of global R&D. Two trends have caused this shift. 
First, the Federal Government's share of U.S. domestic R&D has 
fallen, with the private sector picking up the slack. Second, 
the U.S. share of global R&D has dropped from nearly 70 percent 
in 1960 to 30 percent today.
    A combination of these trends in the commercialization and 
globalization of research and development has dramatically 
changed the role that DOD plays in technology development. 
Instead of being a trend-setter, DOD is forced to react to 
technology trends exogenous to the defense industry.
    The dominant trend in global technology innovation today is 
the information revolution. Network connectivity and bandwidth, 
big data, AI [artificial intelligence] and machine learning, 
genomics, Internet of Things devices, and computing hardware 
are all advancing at literal exponential rates. To give just 
one example, the amount of computing hardware used to train 
cutting-edge machine learning systems, such as large language 
models like ChatGPT, has grown 10 billionfold since 2010, and 
is doubling every 6 months. This is much faster than the 
historical 24-month doubling in chip performance associated 
with Moore's Law. This has dramatic implications for the 
military. Few other technologies are advancing this quickly. 
Missiles are not 10 billion times faster than they were in 
2010.
    Yet information technologies (IT) are advancing at a 
breathtaking pace, creating new opportunities for military 
applications, and these technologies are so widely available, 
coming out of a highly globalized, commercially driven R&D 
ecosystem, that our competitors have similar opportunities.
    DOD should prioritize investment in digital capabilities 
that are riding these exponential curves--autonomy, robotics, 
sensors, communication networks, data, cloud computing, cyber, 
and electronic warfare, for example.
    We can already see evidence of this dynamic in the war in 
Ukraine, with the proliferation of small, commercially 
available drones and counter-drone electronic warfare and 
jamming systems. Our adversaries will capitalize on these 
technologies. The only question is whether the United States 
also competes or falls behind.
    In recent years, DOD has created a slew of new innovation 
organizations such as DIU [Defense Innovation Unit], AFWERX 
[Air Force Work Project], SOFWERX [Special Operations Forces 
Works], CDAO [Chief Digital and Artificial Intelligence 
Office], and others, and many of these have yielded tangible 
successes. Yet DOD has often struggled to innovate quickly at 
scale.
    The Defense Department must move beyond bespoke solutions 
to one-off problems are scale commercial tech adoption across 
the $800 billion enterprise. DOD will need Congress' support to 
move fast, be flexible, experiment with new technologies, 
engage non-traditional companies, and take risks. Thank you.

    Chairman Reed. Thank you very much, Dr. Scharre.
    Dr. Brands, please.

 STATEMENT OF HAL BRANDS, Ph.D., SENIOR FELLOW AT THE AMERICAN 
    ENTERPRISE INSTITUTE, HENRY A. KISSINGER DISTINGUISHED 
  PROFESSOR OF GLOBAL AFFAIRS AT THE JOHNS HOPKINS SCHOOL OF 
                 ADVANCED INTERNATIONAL STUDIES

    Dr. Brands. Chairman Reed, Ranking Member Wicker, 
distinguished Members of the Committee, thank you for inviting 
me. Let me just make three brief points at the outset here.
    First, it is a perennial cliche to say that the 
international landscape is more threatening and complex than it 
has been at any time in decades. Today that cliche actually 
happens to be true. All three key regions of Eurasia are 
experiencing severe conflict or the threat of conflict. Today 
we have Russia's war in Ukraine, the war between Israel, Hamas, 
and all of the violent spillover it has produced across much of 
the Middle East, as well as the growing threat of conflict with 
China in the Western Pacific.
    When you add in the other persistent threats the United 
States must contend with from an increasingly belligerent North 
Korea to a nuclearizing Iran to the persistent threat of 
violent extremism, I think it is fair to say that the United 
States faces more and more severe security challenges than at 
any time since the end of the cold war, and perhaps even going 
back farther than that.
    Second, to Senator Wicker's point, the connections between 
the threats the United States faces are growing, as is the 
threat of conflict that spans multiple regions. Ties between 
Russia and China, Russia and Iran, Russia and North Korea, and 
China and Iran are all becoming strongly and more tightly 
interwoven, which means that the conflicts in which these 
various actors are engaged, or could engage in, are becoming 
more tightly interconnected, as well.
    I go into this issue in greater detail in my written 
statement, but let me just say that my gravest concern about 
the international security environment right now is not that 
United States adversaries will mount a comprehensive, highly 
coordinated assault on the international order. It is that the 
regional conflicts in which they are engaged will fuel and feed 
on each other, creating an atmosphere of growing global 
disorder.
    As I mentioned, the United States right now already faces 
hot wars in two of the three key Eurasian theaters. If China 
were to attack Taiwan or otherwise violently upend the status 
quo in the Western Pacific, all three key theaters of Eurasia 
would be engulfed in violent conflicts simultaneously, a 
situation the world really has not seen since the run-up to 
World War II.
    Third, the U.S. is not adequately prepared for the world it 
presently faces. For much of the past decade, the U.S. has been 
transitioning toward a one-war defense strategy in a world 
where it could easily face conflict in two or three theaters 
simultaneously. As we have seen since Russia invaded Ukraine, 
the United States defense industrial base would struggle 
enormously if the United States were engaged in a major 
conflict. U.S. defense spending is about as low, give or take, 
as a percentage of GDP, as it has been at any time since the 
late 1940's.
    In other words, there is a growing gap between the 
challenges the U.S. faces and the resources with which it can 
face them. The longer that gap persists and the larger it 
grows, the greater the likelihood it will be revealed by our 
adversaries, at a time and place of their choosing, and at a 
tremendous cost to global stability and our own security. Thank 
you.
    [The prepared statement of Dr. Brands follows:]
   [GRAPHIC(S) NOT AVAILABLE IN TIFF FORMAT]    
      
    Chairman Reed. Thank you very much, gentlemen, for your 
very insightful testimony.
    Dr. Scharre, with regard to technology, could you briefly 
describe the strategy of today and what you see as its 
strengths and weaknesses.
    Dr. Scharre. Yes, of course, Senator. So I think that when 
you look at the DOD's national defense S&T strategy, I think 
one of the things that they have done very well is list a 
number of different critical technologies. DOD, of course, has 
been doing this for the last several years and then updating 
them. The most recent one has a couple different bins that they 
have put these in, which I think is somewhat helpful to 
organize them.
    I think there might be two things that I would suggest 
would be helpful to the Department to do to add onto this. One 
would be a sense of prioritization among these, that can drive 
actually spending and investments. The problem is 14 things is 
not really a list of priorities. It is a shopping list. It is 
just a lot of things. It is all the things.
    To their credit, past DOD leaders, some of them have made 
very clear priorities. When he was Deputy Secretary of Defense, 
Bob Work said robotics, AI, autonomy, his number one priority. 
When he was Under Secretary, Michael Griffin said hypersonics, 
directed energy, his top priorities.
    The concern that I have in looking at this is, you know, 
both things cannot be the number one thing, right? I think it 
would be helpful for the Department to have a repeatable 
process internally, a rubric, for prioritizing technologies 
that they could come then to excellent audiences, to the Hill, 
to industry, to others to say here is our process. These are 
the questions that we ask, looking at where the technology is 
coming from, its operational effects, its rate of growth. Based 
on those factors we have decided these are the ones that are 
the most important. This is the way it is going to drive our 
decisions. A process that everyone else could look at and 
understand it would be transparent. Instead of just kind of 
individual leaders saying, well, I think this is more 
important.
    I think the other factor that I do not see included too 
often is looking at the rate of growth of these technologies, 
which I think matters quite a bit in sort of what do you think 
is going to be most impactful in maybe the relatively near 
future. You need to look at that differential rate of growth.
    Chairman Reed. Thank you very much.
    Dr. Brands, before the 2023 Ukraine counteroffensive you 
were urging more rapid support of the Ukrainian Forces. Now we 
find ourselves in a position where we are deadlocked over this 
supplemental. What is your view on the importance of the 
supplemental and the timing of getting it done?
    Dr. Brands. I think it absolutely crucial in the sense 
that, one way or another, 2024 is going to be a difficult year 
for Ukraine, where they will largely be on the defensive. The 
question is whether 2024 can be a year in which Ukraine can 
resist Russian advances and prepare itself for another 
counteroffensive, perhaps in 2025, and the supplemental is 
absolutely vital on both of those counts. Without additional 
United States aid there just will not be the wherewithal to 
mount another offensive, and as we are seeing right now, 
without United States aid Ukraine will start to run critically 
short of capability that it needs just to hold the line where 
it is.
    The Ukrainian withdrawal from Avdiivka was occasioned 
largely by the fact that Ukrainian Forces simply did not have 
the ammunition to hold very strong defensive positions that 
they held there. When you take into account that most Ukrainian 
defensive lines are not as well developed or strong as the ones 
that they had to leave in Avdiivka, the reality is that if they 
do not get this aid from the United States they are going to 
find it very difficult just to keep the line in place over the 
course of this year, which will further complicate the question 
of how the war ends on terms successful for Ukraine.
    Chairman Reed. Following that up, you have made the point 
that the danger might not be a concerned axis of enemies that 
come after us together but one exploiting the fighting in one 
region, et cetera. This raises the question of China's kind of 
observation of what is going on in Ukraine. So Dr. Brands, your 
views on that.
    Dr. Brands. I think one of the most constructive influences 
on China's calculus relative to Taiwan over the past couple of 
years has been the degree to which Russia has struggled in 
Ukraine and the degree to which a coalition of countries, 
mainly advanced democracies, has rallied to help support 
Ukraine in its fight for survival.
    I think it would be extremely damaging if the United States 
were essentially to throw in the towel in Ukraine and to allow 
Ukraine to be defeated, because the message that would send to 
Xi Jinping and other people who are observing United States 
behavior very closely is that the West may talk tough but 
ultimately you can outlast the United States and get your way 
in the end.
    Chairman Reed. Thank you, and I will let the Ranger get the 
last word. Do you concur, Dr. Scharre?
    Dr. Scharre. I do, absolutely, and I do think that, as Dr. 
Brands points out, our threats would worsen in Europe if we 
were to not continue to support Ukraine. In the end we would 
have an emboldened, stronger Russia as a result, which would be 
a much larger burden for us in terms of defending our allies in 
Europe, and the effects would be felt around the world, 
including most acutely with China, and impact their calculus.
    Chairman Reed. Thank you very much. Senator Wicker, please.
    Senator Wicker. Thank you, Mr. Chairman. Dr. Brands, let me 
ask you about the National Defense Strategy (NDS). The law 
requires the Secretary of Defense to review the adequacy of the 
strategy and update it if circumstances have changed.
    Now we got the latest strategy in October 2022, 17 months 
ago or so. Do you think events have changed? Do you think this 
situation has changed enough over that time that the Secretary 
needs to review the adequacy of the strategy and make changes?
    Dr. Brands. I think two critical things have changed since 
the strategy was finalized and released in 2022. The first is 
that the assumption that Russia would emerge from the Ukraine 
war significantly weakened and ultimately defeated is no longer 
as tenable as it once was. We are seeing a Russia that is doing 
fairly well on the battlefield right now, and furthermore, is 
aggressively mobilizing economically and militarily in a way 
that will allow it to present a continuing threat to the 
eastern front of NATO for many years to come after this war 
ends.
    The second thing that has changed, obviously, is that the 
Middle East has erupted once again. This was not a calculation 
that was foremost in the crafting of the National Defense 
Strategy. We are seeing increased persistent demands on United 
States military power in the Red Sea, in the Gulf of Aden, in 
Iraq and Syria, and in a variety of other places where the 
United States is trying to push back against Iran and its 
proxies.
    So when you put those two things together I think it 
indicates that we are living in a rather different world than 
was expected when the strategy was released.
    Senator Wicker. Do we ever adequately fund the National 
Defense Strategy?
    Dr. Brands. Well, ``ever'' is a strong statement. I guess I 
would say that the gap between our requirements and our 
resources is bigger at times and smaller at times, and I worry 
that it has gotten bigger in recent years. If you just think 
about defense spending as a percentage of GDP, during the cold 
war the United States spent, on average, about 7.5 percent of 
GDP on defense. During the 1980's, during the period of the 
Reagan buildup, it was about 6 percent, 6.5 percent, on 
average. We are at about half of that today, just north of 3 
percent.
    When you compare that at the threat landscape that the 
United States faces to historical trends of defense spending, I 
think indicates that the gap between resources and commitments 
is getting larger.
    Senator Wicker. Well, sir, in a recent Foreign Affairs 
essay, you mentioned that it is going to be hard to 
dramatically ramp up military spending until it is politically 
expedient, and you mentioned the possibility of Americans being 
convinced only in the case of a jarring geopolitical shock.
    But let me ask you to comment on that. we had a jarring 
political shock in Pearl Harbor, because we were not ready. 
During that time you mentioned that we were spending 6, 7 
percent of GDP the cold war. We never really had a jarring 
shock, did we?
    Dr. Brands. We had shocks that were lesser than Pearl 
Harbor but that did catalyze significant growth in U.S. defense 
spending. So the Korean War, for instance, that led to a 
massive expansion of United States defense spending from I 
believe somewhere in the neighborhood of 3 or 4 percent of GDP 
up to about 14 percent of GDP, at the height of that conflict.
    Senator Wicker. Okay, and let's move ahead to the Carter 
administration, the end of the Carter administration, and then 
the beginning of the buildup in GDP under Reagan. What were 
those numbers?
    Dr. Brands. I believe at its peak under the Reagan 
administration the U.S. was spending north of 6 percent of GDP 
on defense.
    Senator Wicker. We avoided during that time a jarring 
geopolitical shock, did we not?
    Dr. Brands. Yes.
    Senator Wicker. Dr. Scharre, just real quickly, the 
technologies are important. In my opening statement I said we 
need more submarines, we need more amphibs, we need more 
missiles. The fact that we need to gain the lead in DOD in 
technologies does not take away from the fact that we need more 
tools, more ISR [intelligence, surveillance, and 
reconnaissance], more missiles, more ships. Is that correct?
    Dr. Scharre. Yes, I think that is true. I mean, we 
obviously need physical platforms. We need ships. We need 
submarines. I also think it is true--and I think, actually, the 
Department understands this--that what is on those platforms 
matters more than just the raw numbers. But we do need numbers, 
and that is a major problem right now for the Department.
    Senator Wicker. Lack of numbers is a major problem.
    Dr. Scharre. Absolutely.
    Senator Wicker. Thank you. Thank you, Mr. Chairman.
    Chairman Reed. Thank you, Senator Wicker. Senator Hirono, 
please.
    Senator Hirono. Thank you, Mr. Chairman. So we already 
spend north of $800 billion for defense. Dr. Brands, you are 
suggesting that we double this to over a trillion. So it is not 
just how much we are spending, it is what we are spending on, 
is it not? So are we spending defense dollars in the kind of 
priorities that you would expect us to be spending this money 
on?
    Dr. Brands. I think there are many constructive initiatives 
underway within the Department to try to prepare the U.S. for 
some of the conflicts that it might face. So I think a lot of 
the operational concepts that are being devised by the services 
that are geared toward conflict in the Western Pacific are 
promising.
    I think, though, that ultimately all of those concepts 
require munitions, they require platforms, they require a 
number of things, where quantity really does matter, and so I 
think that while it is very important that we have the thrust 
of our defense program right. It is very important that we 
resource it adequately, as well.
    Senator Hirono. Well, when you said quantity does matter, 
because at some point the fact that China has so many more 
quantities of planes and ships and everything else. Our 
country, we could meet the challenge of China, for example, 
through innovation. Both of you are now saying that we are 
falling behind in our technological innovation. You say, Dr. 
Brands, that the NDS, which came out sometime in late 2022, is 
already not accurate with regard to Russia's powers and also 
what is happening in the Middle East.
    What do we need to do to make sure that we are actually, we 
have the capacity to assess the needs that we have militarily 
based on what is going on in the world. Not to mention, by the 
way, how important are the alliances that we have at a time 
like this when we are facing the conflicts in the Middle East 
and in Russia and Ukraine? Either one of you.
    Dr. Brands. I can talk about alliances and perhaps the 
assessment issue. We have been fortunate over the past couple 
of years in that we have gotten a real-time education in 
demands that modern war and major war would present for the 
U.S. Defense Department. We have seen in Ukraine the enormous 
quantities of munitions and platforms that would be consumed by 
a war between the United States and Russia, let alone the 
United States and China. So I think we have gotten a greater 
education in sort of the order of magnitude of what a major 
conflict would demand.
    On the question of alliances, just briefly I would say that 
alliances are perhaps our greatest force multiplier in 
international affairs. They give us access and influence in key 
regions. They allow us to advocate the capabilities of other 
countries to our own. They give us the ability to influence the 
calculations of adversaries in an important way. In those and 
other ways, I think they add dramatically to the influence the 
U.S. can observe on the international stage.
    Senator Hirono. I agree with you, and recently we have the 
Quad Alliance, the AUKUS [Australia, United Kingdom, and United 
States] agreements, trilateral relationship with the Republic 
of Korea, Japan, and us, the renegotiation of funding of the 
compact nations. So those are all very critical to our ability 
to be ready in meeting, I think, the demands of the near-peer 
people in China and Russia.
    I am just curious. You both talk about how we are falling 
behind in terms of our technological decisionmaking. We 
recently got the report of the National Defense Industrial 
Strategy. So do we need some kind of a national defense that 
focuses on technological advancement?
    Dr. Scharre. Yes, I think the new strategy and the defense 
industrial base was excellent, and I think actually the big 
challenge there is resourcing it. Because, in particular, the 
Ukraine conflict has highlighted for us these particular 
problems that we have seen in the defense industrial base, 
especially in munitions procurement. It has given us, in many 
ways, a golden opportunity to address those problems now, ahead 
of a potential conflict with China, both to increase munitions 
capacity and then scale production, and then look elsewhere in 
the defense industrial base where we probably have similar 
problems.
    Senator Hirono. Well, but you both highlighted that we are 
falling behind in terms of our technological capabilities. So 
do we need to have a special group, within an entity, or the 
development of a strategy that focuses on DOD capabilities in 
the technology area? Do we need a specific group that is paying 
attention to that need within DOD?
    Dr. Scharre. I think so. I think maybe there are two maybe 
challenges I would see. One would be some improvements to how 
DOD thinks about S&T [science & technology] investments itself 
in terms of the prioritization and the trends. But also at a 
national level we are now competing with China at a national 
level in technology competition, and we do not really have 
anyone at the national level looking at that holistically. We 
have seen not just DOD but Commerce and other elements of 
national power come into form. I think we need to think more 
strategically about how to use those elements of national 
power.
    Senator Hirono. Do you agree, Dr. Brands? I am running out 
of time, but maybe you can respond briefly.
    Dr. Brands. Yes.
    Senator Hirono. Thank you. Thank you, Mr. Chairman.
    Chairman Reed. Thank you, Senator Hirono. Senator Fisher, 
please.
    Senator Fischer. Thank you, Mr. Chairman. Dr. Brands, many 
analysts today, they seem to be relatively confident that the 
risk of Chinese aggression is overblown. Do you think that 
confidence is misplaced?
    Dr. Brands. I would not hold a great degree of confidence 
in our ability to predict that China will not use force in the 
Western Pacific over the next several years, in part because 
even if it is not to China's advantage to do so, we have seen 
from the Ukraine war and many other cases in history that the 
leaders often make bad decisions. They often make bad decisions 
when they sit atop authoritarian regimes where information flow 
is very restricted and there is a lot of incentive to tell the 
person at the top what he or she wants to hear.
    I worry also because the reality is that the military 
balance in the Western Pacific is changing dramatically, and it 
is changing in real time. The United States has done a variety 
of important and constructive things over the past several 
years to try to arrest the erosion of deterrence. Everything 
from the coalition-building efforts that have been discussed to 
some of the operational concepts that are being put in place 
today. But the reality is that the scale of the PLA buildup is 
just such that I worry we are losing rather than gaining 
ground.
    The one statistic that always stands out to me is that 
between 2022 and 2023, the PLAAF [People's Liberation Army Air 
Force] added 400 fourth-generation fighters, so basically F-16 
equivalents, to its inventory. When you start getting into 
numbers like that, even a qualitatively superior military, 
which the United States clearly has, may struggle to defend 
Taiwan or otherwise uphold its commitments in the region.
    So as this decade goes on, if the balance continues to 
shift I would become more worried about the PRC's [People's 
Republic of China] propensity for aggression.
    Senator Fischer. Dr. Brands, the United States has relied 
heavily on sanctions against Russia. When we watch the 
aftermath now of that in Ukraine it has failed to destroy. 
Russia's economy was initially anticipated, you spoke to that 
earlier, that the Russians are moving ahead with that. Do you 
think that China would be more susceptible or less so to those 
sanctions than Russia, and why?
    Dr. Brands. I think it is complicated, Senator. On the one 
hand, China is a harder sanctions target than Russia because 
its economy is bigger, it is more diversified, and I think the 
financial implications of going after the Chinese economy in 
the way that the United States and its allies went after the 
Russian economy would be more globally severe than they have 
been in the Russian case. So for all of those reasons it might 
be more difficult to inflict even the level of pain on China 
that the United States and its allies have done to Russia.
    The flip side of it, however, is that China is also, 
because it is more globally integrated it is more dependent on 
the global economy than Russia is. So the threat of having 
access to Western markets severed would, I think, be more 
impactful for China than it would for Russia, because I do not 
see how China can accomplish its objectives without access to 
the global economy over time.
    Senator Fischer. Dr. Scharre, do you have any comments on 
the sanctions on China, what we would see there?
    Dr. Scharre. Yes, thank you, Senator. Actually, a colleague 
of mine, Emily Kilcrease, at the Center for a New American 
Security, recently released a very detailed analysis of this, 
and I am happy to share it with you all afterwards. Looking at 
different elements of China's economy and their exposure to 
potential sanctions. There are a lot of areas, particularly in 
the defense sector, that are fairly insulated because they are 
not tied into the global economy, but their banking sector, in 
particular, is one that does have some vulnerabilities.
    I think those are places where we want to think 
strategically about how do you leverage that? How do you 
sustain those vulnerabilities, because China is certainly aware 
of them, and they are looking to shore up their defenses and be 
less vulnerable. How do you sustain those? Then in the run-up 
to a potential conflict, how would you think about 
strategically leveraging them, potentially as a means of 
deterrence, which is a new way of thinking about sanctions than 
we have necessarily done in the past, but I think there is a 
lot of value there.
    Senator Fischer. How would you both characterize the 
relationship between Beijing and Tehran?
    Dr. Brands. I think that China has been investing in this 
relationship over the past few years in hopes of strengthening 
its ties to a key player in the region. I think that China, 
however, has to balance its relationship with Iran with its 
efforts to deepen its relationship with Saudi Arabia and other 
key states in the gulf. So there may be a Governor on how far 
the China-Iran relationship can go that is less present in 
other cases where you have autocratic countries coming 
together.
    Senator Fischer. Thank you very much.
    Chairman Reed. Thank you, Senator Fisher. Senator Kaine, 
please.
    Senator Kaine. Thank you, Mr. Chair, and thank you to the 
witnesses.
    Dr. Brands, you talked about China's perception of the slow 
pace of Russia in Ukraine, and that that has affected their 
thinking about their own military ambitions. In particular you 
cited China's observation that when the democracies link arms 
it is pretty formidable. We do not have NATO in the Indo-
Pacific, but we do have sort of a latticework of alliances--the 
Quad, the improved relationship between Korea and Japan, an 
improving relationship with the Philippines, and AUKUS.
    I would like you to each talk about--this Committee has 
done a lot of work on AUKUS, as has the Foreign Relations 
Committee. There is funding for some parts of AUKUS in the 
supplemental bill pending in the House right now. I would like 
you to talk about how you view the AUKUS framework Pillars 1 
and 2 in terms of our security posture in the Indo-Pacific.
    Dr. Brands. I think it is incredibly important in a handful 
of different respects. In one respect, simply the geography of 
AUKUS is very important because it is proof of concept of how 
the United States can leverage individual alliances in order to 
bring countries together into a larger network of actors that 
are committed to pushing back against Chinese power, even when 
those countries span regional boundaries.
    Obviously, the piece of AUKUS that gets a lot of attention, 
and rightly so, is the submarines piece of it, and that is 
important because undersea warfare is, I think, one of the few 
areas where the United States still enjoys unquestioned 
superiority over China, even at the vast distances of the 
Western Pacific.
    Because it will take some time for the submarine dimension 
of AUKUS to really bear fruit, I think the other pieces of it, 
whether it is the advanced capabilities piece or sort of the 
accompanying piece, which is increased access and presence in 
northern Australia, are particularly important in terms of 
developing the ability to bring power to bear in a conflict in 
the Western Pacific and affecting China's calculations in terms 
of how a conflict would go over the next 5 to 10 years.
    As important as that is in its own right it is also a 
critical bridge to the point where you can start to bring some 
of the undersea capabilities to bear.
    Senator Kaine. Dr. Scharre, other thoughts?
    Dr. Scharre. I think given the timing dimension I might 
prioritize things that involve joint exercises, things that 
demonstrate to China that jointness in our ability to operate 
with our allies in the region, things that involve basing 
posture kind of things. I would, in particular, emphasize 
things that are not physical capabilities but institutional 
elements of collaboration. So things like joint planning 
together, which we already obviously have deep ties with 
Australia and the U.K., but things like bringing them on board 
in terms of planning to actually, in the event of a conflict, 
enable us to be able to fight effectively together.
    Senator Kaine. Australian sailors are already going through 
the training program at the nuclear power school with United 
States Navy and in South Carolina Australian shipbuilders are 
already here training at a manufacturing excellence facility in 
Danville, Virginia. So we are moving out before the sub 
transfers in the 2030's, which I am impressed by.
    Let me conclude with an area where I am not happy with 
alliances and that is the Red Sea. I am worried about the lack 
of a real strategy in the Red Sea with the Houthis trying to 
defend shipping, I think, makes some strategic sense. But 
President Biden and others have acknowledged they do not think 
firing more missiles at the Houthis is going to lead the 
Houthis to fire fewer missiles. In fact, it seems like the pace 
might be escalating.
    In particular I am concerned that the burden of defending 
commercial shipping in the Gulf of Aden and the Red Sea is 
pretty heavily on the U.S.'s shoulders. I think it is just the 
United States and the U.K. that are engaged in any kinetic 
activity to knock down Houthi drones and missiles. I believe 
the Italian navy might have engaged in one kinetic activity to 
protect an Italian-flagged vessel.
    Why are not more nations engaging in this defense in the 
Red Sea when their probably commerce and trade is more affected 
by the Houthi attacks than is the United States economy?
    Dr. Brands. Senator, I think the basic problem is that many 
of them do not have the capability to do so. Even in cases 
where our allies might be included to help out in providing 
this critical public good they are running short of the 
resources. So Australia had their debate about whether they 
would contribute to Operation Prosperity Guardian and 
ultimately decided they would not, because I believe Australia 
has a total of three ships that could be useful in this sort of 
context, and they have decided that they are needed closer to 
home.
    So the lack of resources relative to challenges 
unfortunately is not a distinctly American problem. It is a 
larger free world problem at this moment.
    Senator Kaine. I yield back. Thank you, Mr. Chairman.
    Chairman Reed. Thank you very much, Senator Kaine. Senator 
Schmitt, please.
    Senator Schmitt. Thank you, Mr. Chairman. Thank you both 
for being here. Dr. Brands, in your book I am really interested 
in the Danger Zone book, and how you balance, in trying to 
understand the Chinese perspective, they certainly view 
themselves as a 5,000-year-old civilization, the middle 
kingdom, who, the last 200 years, has been an aberration, a 
humiliation, in their view. They are not going to let that 
happen again, they have a longer view, all those sorts of 
things that are sort of baked into the understanding of their 
mentality and how they are on the march now, in a very real 
way, and probably more than people think. Their shipbuilding 
capacity alone is striking, and I am not sure many people in 
the general public understand that. They have a bigger navy--
not a better navy, but a bigger navy.
    So that longer view, and you write about the 2020's being 
absolutely critical, which is a very short-term issue in 
setting the stage for this longer, great powers competition. 
You have got the demographic cliff that they are facing. They 
are no longer publishing a lot of economic data. Their youth 
unemployment, which I think drives--GDP is really important to 
us. I think unemployment for the Chinese is most important, for 
a variety of reasons. When you are an authoritarian regime a 
lot of young men not working is a real problem.
    So how do you balance this, in your view of how they view 
where they are at right now--and, of course, you have got this 
big Taiwan question--where they are at right now. Do they view 
that as, in your estimation, as a reason to go quicker, or do 
they fall back to the traditional view of the longer-term 
strategy?
    Dr. Brands. Senator, my view--and this is by no means a 
unanimous view among China watchers, I should add--but my view 
is that China is being motivated by a dangerous mixture of 
weakness, strength, and personalization at this point. The 
weakness comes from the demographic and economic problems that 
you noted, which are already having a pronounced effect on 
Chinese growth, and that effect will only become more 
pronounced over time. At the same time, the military 
modernization program is still going gangbusters, if you look 
at the increases in military spending.
    You have a country whose long-term economic prospects are 
dimming as its near-term military position becomes stronger. 
Historically, that has been a recipe for trouble, because that 
is exactly the sort of combination that tempts countries to use 
force sooner rather than later to lock in advantages while they 
still can. It is reinforced, in this case, because China's 
fortunes have become increasingly entangled with Xi Jinping's 
fortunes, as he personalizes the political system and does away 
with this system of something closer to collective rule that 
China had for a couple of generations after Mao Tse-Tung.
    You sometimes hear Xi Jinping say things like, ``The 
question of Taiwan cannot be passed down from generation to 
generation.'' That is sometimes read as him saying, ``It cannot 
be passed down to the next generation of Chinese leaders.''
    When you put all those things together it makes me worry 
that we may be dealing with a China that is in a bit of a hurry 
by the time we get to the latter part of this decade.
    Senator Schmitt. He is already in an unprecedented third 
term.
    Dr. Brands. With no indication that he is planning on 
stepping down any time soon.
    Senator Schmitt. Correct, and so if you were a betting man, 
if you had to place a wager, red he goes, black he does not go, 
where are you betting?
    Dr. Brands. I think an operation against Taiwan would be 
sufficiently daunting that there are lots of things that the 
United States, Taiwan, and other countries in the region can do 
to drive down the chances of a Chinese attack on Taiwan. But on 
the current trajectory I am very worried about where we will 
end up.
    Senator Schmitt. Then one last question about the CCP and 
China. So there has always been this sort of natural distrust 
between them and Russia, or the USSR [Union of Soviet Socialist 
Republics], or the Russian Empire, whatever phase Russia is in. 
How do you view that? Even though they seem to be working more 
collaboratively than they have in recent memory, there is still 
this natural tension. They share a border. How do you gauge the 
reality of that relationship right now?
    Dr. Brands. The historic mistrust is still there. In fact, 
China will occasionally print maps that show it controlling 
parts of Russia, as it is currently constituted. Certainly I 
think the Russians, in particular, know that if China comes 
anywhere close to achieving its ambitions in Eurasia that is 
going to be a very challenging situation for Russia itself. 
Those concerns are rather distant at the moment.
    Ideologically, these are two countries. They are both 
autocratic powers trying to make it in a world dominated by a 
democratic superpower. They both view the United States and its 
allies as their primary enemies, and by all indications, Xi and 
Putin seem to have similar world views and get along fairly 
well.
    So those historic tensions may reassert themselves, but 
perhaps not on a timeline that would help us in this decade or 
a little bit beyond.
    Senator Schmitt. So maybe the United States exploiting some 
of those traditional differences as opposed to driving them 
together probably makes the most sense for us, right?
    Dr. Brands. It could. I will spare you a long excursion 
into history, but if you look back at the prior Sino-Soviet 
relationship, the United States actually pursued a strategy in 
the 1950's of trying to drive them closer together as a way of 
exploiting those frictions within the relationship. I would 
argue that it worked fairly well at the time.
    Senator Schmitt. Okay. Thank you.
    Chairman Reed. Thank you, Senator Schmitt. Senator King, 
please.
    Senator King. Thank you, Mr. Chairman. I would like to 
thank both of you for very thoughtful and insightful testimony. 
Talking about some of the issues that we have already touched 
upon, in 1962, as you have testified, our defense was something 
like 8 or 9 percent of GDP. Today it is under 3 percent. The 
projection I just saw was 2.7 for 2024.
    The cornerstone of our national security policy is 
deterrence. I would argue that this dramatic decline, by two-
thirds, is a chink in the armor of deterrence. Would you 
concur? In other words, the Chinese and the Russians and others 
look at that number as part of measuring how fearful they 
should be of our ability to respond.
    Dr. Brands. I think it is certainly unhelpful, Senator, and 
I think that whether it is the number they look at or the speed 
at which the U.S. would exhaust its munitions inventory in a 
particular conflict, those are precisely the sort of issues 
that would worry me about whether deterrence was eroding.
    Senator King. The second question along those lines is our 
failure to continue to support Ukraine, how would that affect 
Xi's calculus in terms of Taiwan and his analysis of our 
staying power?
    Dr. Brands. I think Xi is predisposed to think that the 
United States and its allies lack the endurance and the stamina 
to hold the line against China and its partners over the long 
term. If the United States were to terminate support for 
Ukraine or would allow Ukraine to be defeated, I think it would 
simply reinforce that perception. Which would be unhelpful, as 
Dr. Scharre had pointed out, not just in Europe but in the Asia 
Pacific as well.
    Senator King. Dr. Scharre, do you agree?
    Dr. Scharre. Absolutely. I mean, Xi already believes that 
America is in decline. That we do not have staying power, and 
it would certainly reinforce that assumption that even in the 
event of a conflict, if the United States were to be directly 
engaged in defending Taiwan, that we simply would not be able 
to go the distance and China could outlast us.
    Senator King. My impression from the initiation of the 
Ukraine war was that Xi was somewhat surprised by the reaction 
of the West, the unification, expansion of NATO, and that 
surprise and concern would be dissipated if we indeed abandoned 
Ukraine.
    Dr. Scharre. Right. Precisely.
    Senator King. I like it when witnesses say precisely in 
answer to a question.
    I want to go back to the very beginning, and also I want to 
associate myself with the questions of Senator Wicker in terms 
of the GDP percentage. The American public does not realize, we 
hear this big number, $800 billion, and at ten times other 
countries, but in terms of the percentage of our economy 
devoted to defense it has fallen by almost two-thirds in the 
last 60 years.
    R&D, real problem. New technologies win wars. Genghis Khan 
conquered the world because of the invention of the metal 
stirrup. The longbow turned the tide. The British had 5,000 at 
the Battle of Agincourt, the French 20,000. The use of the 
longbow was generally considered by historians to be crucial in 
turning that battle, and indeed, the 100 Years War.
    I worry, it is obviously that there are new technologies 
that we have been slow. Directed energy and hypersonics are the 
two that strike me as most obvious. How do we get the Pentagon 
to understand the role of new technology? Dr. Scharre, what is 
your view?
    Dr. Scharre. I think that the Defense Department, basically 
in its DNA, understands the value of technology. I actually 
think what is missing right now is a sense of where the 
priorities ought to lie, because I think the DOD is still stuck 
in a mindset from the 1960's where DOD believes that it has to 
invent all the technologies itself. But there is so much 
technological innovation happening outside the Defense 
Department that I think that is going to matter more.
    I would say that it is true that technology is absolutely 
critical to winning wars, but what matters most is finding the 
best ways of using the technology. That is clear looking at 
history. So having institutional processes that can figure out 
how do we capitalize on this. Because in many ways----
    Senator King. One of the problems--we have had testimony to 
this Committee that smaller companies in Silicon Valley do not 
even bother applying for contracts to the Department of Defense 
because it is so cumbersome, slow, and we are losing access to 
innovation.
    Dr. Scharre. I would actually, so even worse, we are 
building barriers to access, right. Those barriers are self-
constructed by us, red tape that makes it hard for companies 
that would like to work with DOD to work with us. So we need to 
find ways to tear down those barriers.
    Senator King. In the meantime, we are spending $5 million a 
missile to knock down $200,000 to $300,000 drone out of the 
Houthis, when directed energy could do it for about 50 cents a 
shot. We have just got to break down this barrier, both in 
terms of working with smaller and innovative companies but 
also, as you say, taking advantage of technologies developed in 
the private sector and then transferring them into our arsenal, 
if you will.
    Thank you very much, Mr. Chairman. I yield.
    Chairman Reed. Thank you, Senator King. Senator Gillibrand, 
please.
    Senator Gillibrand. Hi. Thank you so much for your 
testimony today. I want to ask some larger questions.
    The United States has always had a theory that mutually 
assured destruction and deterrence would restrict an adversary 
from taking the United States on domestically anywhere in our 
country. We have an assumption that we would never have to 
defend a war here in the United States. Well, that assumption 
does not play out when you are looking at the arena of cyber or 
AI or other types of disruption that could be lethal.
    We have seen cyberattacks over the last 5 years in an array 
of places--solar winds, shutting down our supply chain for 
food, affecting oil production and delivery. We have seen 
cyberattacks in every industry, whether it is in health care 
most recently, or in banking, or in any domain within the 
United States.
    Yesterday I sat on the Intel hearing, and asked each of the 
witnesses, from Director Burns to Director Haines and other 
military personnel doing intelligence for DIA and other 
entities. I asked them the question of--I gave one example, 
let's say an adversary decides to use AI and different kinds of 
generated content to spew out false information from an elected 
leader or a candidate to such a degree that it misleads the 
American public in a U.S. election. What are you doing to 
prevent that or to respond to that efficiently, and who here is 
responsible for telling the American people the facts of any 
given incident? None of them had a plan, and none of them took 
responsibility for the protection of the United States.
    I would like to get your assessment of how do we protect 
the United States? Let's just say China, in its effort to 
invade Taiwan, uses the first 2 or 3 months to just do as many 
cyberattacks as possible in our critical infrastructure, around 
our bases, around our ability to launch from, let's say Guam, 
which they just tested a few months ago. Takes our electric 
grid, takes out our capacity, creates chaos, undermines the 
economy significantly. We have no plan to defend against that. 
I think the response is, well, you have got the FBI [Federal 
Bureau of Investigation], which is a response organization, you 
have got CISA [Cybersecurity and Infrastructure Security 
Agency], which can offer best practices but has no mandate, but 
you have no one who is in charge of protecting anything in 
CONUS [Continental United States].
    I would like you to talk about how should we realign our 
assessment of what the role of the Department of Defense, NSA 
[National Security Agency], CIA [Central Intelligence Agency], 
National Security Operations and Forces, what is the 
responsibility to protect America from an attack from an 
adversary in the United States, whether it is cyber, to create 
chaos and death and destruction, or any other type of attack, 
from, you know, drones attacking our bases, or spy balloons 
hovering over our most secret assets. What should the United 
States be doing?
    Dr. Scharre. Well, thank you, Senator. I would look at both 
of these, the cyber dimension and the disinformation one, as 
warning shots that we are getting now, none of which have been 
critical yet to the U.S. but we have an imperative to respond 
to these, to shore up our defenses.
    I think on the cyber front there is clearly a lot more we 
could do. We continue to have challenges. As you point out, 
just recently in the health care system, and putting the onus 
on industry putting in place government standards for 
cybersecurity across a wide range of sectors that has been 
critical to be shoring up our defenses here.
    On the disinformation, too, there are a wide range of 
things that we could be doing. For example, requiring that AI-
generated content is watermarked and is labeled appropriately 
when it is online. Something like a bot disclosure law, that if 
someone is using AI--California has this--they have to share 
that it is AI generated, and then cracking down on foreign 
efforts to message, whether using AI or elsewhere, and spread 
disinformation here in the United States, are all things that I 
think we should be doing now.
    Dr. Brands. Senator, I would not add anything substantial. 
I would just say that when the United States war games 
potential Taiwan conflicts or things like that, the Homeland 
dimension is often the piece that gets short shrift, in large 
part because, you know, war-gaming is traditionally a DOD 
competency so it focuses heavily on that aspect of the 
response. But the more that you can get relevant stakeholders 
together to really game through what the domestic disruptions 
would be in this sort of conflict, the more I think you can get 
them talking about the ways in which their responsibilities 
might overlap or where they might need to develop new 
competencies in order to defend the U.S.
    Senator Gillibrand. Thank you.
    Chairman Reed. Thank you, Senator Gillibrand.
    Gentlemen, thank you for your excellent testimony. I have 
one questions which was frequently overlooked today, and that 
is we are emerging into a new world of nuclear competition 
between three powers. Not bipolar competition which shaped the 
whole theory of deterrence, and then, of course, we have the 
other nuclear entities--North Korea, Pakistan, and other 
countries.
    So what is your take on how we should address this nuclear 
issue?
    One other point I would make is it used to be the custom of 
every presidency to seek out at least one agreement with the 
Russians, even if it was a minor one. But we have not had much 
discussion about Russia, and China, I do not think, will talk 
to us until they get up to our level of missiles. But this is 
an issue that is overlooked often, and since I have two 
extremely intelligent gentlemen here, your view. I will start 
with Dr. Scharre, please.
    Dr. Scharre. Thank you, Senator. I would actually argue 
that we have three interlocking problems. There are others that 
complicate what you are describing. There is certainly the fact 
that we are moving into a tripolar nuclear era, with China's 
nuclear buildup. We have emerging technologies that are 
complicating a lot of the strategic dimensions, maybe outside 
of nuclear weapons, but in space and elsewhere, of nuclear 
deterrence. Then also, of course, we have seen with Russia an 
increased salience of nuclear weapons, and a risk that we may 
actually see them used in ways that maybe are heightened from 
what we might have thought a couple of years ago.
    I think it is clear that we need increased investments in 
this space, that if we are going to maintain a deterrent 
against two adversaries simultaneously we are going to need 
more dimensions here. The simultaneity problem is, I would 
argue, most acute in the nuclear dimension because of this 
issue, more so than in the conventional space.
    I think we are also going to need a lot of new thinking. 
The reality is that sort of among the defense intellectuals 
that work on these topics, the sort of nuclear community has, 
over many years, atrophied because nuclear weapons have not 
been as salient until more recently. So I think increased war-
gaming and studies and investments to buildup that intellectual 
capital and to get senior leaders thinking about these 
challenges. Okay, if an adversary uses a nuclear weapon in a 
conflict to try to maybe terminate on their terms, how do we 
respond accordingly?
    Chairman Reed. Thank you. Dr. Brands, please.
    Dr. Brands. Just three things, very briefly. One, the 
scenarios that we worry about nuclear use now I think are very 
different than they were during the cold war. Now what we worry 
most about is sort of limited nuclear use or coercive use to 
back up limited conventional aggression as opposed to in a 
conflict that would engulf Europe as a whole. Which indicates 
to me that the United States is probably going to need more 
investment in limited nuclear capability of its own to close 
the gap between the conventional arsenal and the strategic 
deterrent.
    The second is that the force sizing issue becomes 
particularly complicated in a tripolar nuclear environment. 
Because having enough to assure a second strike capability 
against one adversary, that may not do you much good if you 
then find yourself in a position of inferiority against 
another. So I am not convinced that we have given that the 
attention that it deserves.
    The third is that, unfortunately, I think bilateral United 
States-Russia arms control is probably dead for the foreseeable 
future. The good news is that that gives us a chance to rethink 
what sort of arms control agreements might be to United States 
advantage in an environment where most of them may need to be 
trilateral rather than bilateral to begin with.
    Chairman Reed. Just a final point before I recognize 
Senator Kelly, it may have been that China, for their own 
benefit, gave us a little help in Ukraine. Because I think they 
were very, very much opposed to Putin's threats to use nuclear 
weapons. Not because of Ukraine but because they do not want to 
see South Korea, Japan, et cetera, become nuclear powers.
    It is a complicated world, and it is a new world for us 
now, and I think we have to approach it that way. But thank 
you.
    Senator Kelly, please.
    Senator Kelly. Thank you, Mr. Chairman, and thank you to 
both of you for being here today.
    As a Member of the Senate Intelligence Committee, I see 
firsthand the importance of intelligence gathering to our 
national security and also to strengthening our international 
partnerships. Building these relationships is vital to advance 
our shared goals and protect the American people.
    As you said recently, Dr. Brands, quote, ``strategy is the 
art of balancing power without subverting democratic purpose,'' 
unquote, and there is clearly an art to successful intelligence 
partnerships. Can you speak to how intelligence partnerships 
are vital to the art of national strategy?
    Dr. Brands. Senator, I have looked at this mostly in a 
historical context during the cold war. I guess I would say 
that just as alliances are a force multiplier in general, they 
are certainly a force multiplier when it comes to intelligence. 
One of the things we found historically is that through our 
intelligence liaison programs with allies we may gain access to 
expertise on particular countries or regions that we have not 
invested in heavily ourselves. If we look at the way that 
Australia, for instance, can be helpful in understanding events 
in the South Pacific.
    We may also gain access to particular sources, human 
sources, that the U.S. intelligence system may not have access 
to itself, and so we end up being in a stronger national 
position by dint of the relationships that we have with other 
countries in this realm.
    Senator Kelly. One concern I have had lately is our ability 
to gather intelligence in North Korea. We have got an 
unpredictable actor with an arsenal, and without the 
intelligence flowing in our direction it is just really hard to 
make predictions on what he is going to do.
    A little bit more on Ukraine. Dr. Brands, you have also 
written extensively on our need to provide support to Ukraine. 
I agree that this is one of our top priorities. You know, Putin 
is not going to stop with Ukraine if we do not stop him in 
Ukraine.
    In addition to supporting them militarily, can you give 
your perspective on building an intelligence partnership to 
support Ukraine in its struggle against Russia?
    Dr. Brands. From what I read in the news, United States 
intelligence support to Ukraine has been absolutely vital in 
everything from helping the Ukrainian Government understand the 
nature of the threat that was coming at it in February 2022 and 
after, to providing more actionable insights in the months and 
years that have followed.
    But I would also, Senator, encourage people to think about 
it, the other way around, where the United States will gain 
enormous benefits from an intelligence partnership with 
Ukraine. Because just to put it very bluntly, Ukraine has 
fought Russia and we have not. Ukraine has gained insights into 
the way that modern war works in a high-intensity environment, 
that even the United States military, with all of its 
experience over the last 20-plus years does not have.
    So I would prefer to think of it as a two-way partnership 
in the sense that the U.S. itself will benefit tremendously.
    Senator Kelly. Yes, and not just with intelligence. I have 
made a couple of trips to Ukraine in the last 18 month or so, 
and I made this point with the Ukrainians. At the beginning of 
this conflict. We had much better intel on the Russians and 
experience, combat experience. Fast forward 2 years later, They 
are the ones that have been--they are on the ground here 
fighting every single day and fighting for their lives bravely. 
Now they have that experience, and we have a lot to learn from 
them.
    Dr. Scharre, you have written extensively about the 
importance of AI in military operations. I also noted your 
recent House testimony on the Replicator initiative, which 
intends to field thousands of autonomous systems in about 2 
years. Can Replicators successfully make long-term, fundamental 
changes to the DOD acquisition process?
    Dr. Scharre. I hope so. We will see. I think that DOD set a 
very ambitious goal for itself. I think that is good. They are 
going to need congressional support to make that happen. I 
would like to see them succeed. I think it is too early to 
tell, but hopefully.
    Senator Kelly. In my last minute could you comment a little 
bit about how AI should be integrated into our national 
strategy?
    Dr. Scharre. I guess on a couple of levels. I think 
certainly in the military space we need to be moving forward 
very quickly to bring in AI technology, putting in place the 
infrastructure on data and on computing hardware, cloud 
computing, inside the DOD to make DOD ready for AI, to use it 
effectively. But also nationally we need to protect our 
advantages in AI. The best AI companies in the world are here 
in the United States, and right now the reality is we are 
giving a lot of those advantages for free to China. That a lot 
of the technology proliferates very quickly to China, within 18 
to 24 months. Those best AI models have gone open source, they 
have proliferated to China. I think we also need to look at 
protecting the crown jewels of United States AI advantage.
    Senator Kelly. All right. Well, thank you. Thank you, Mr. 
Chairman.
    Chairman Reed. Thanks, Senator Kelly. Senator Cotton, 
please.
    Senator Cotton. Gentleman, welcome. Dr. Brands, last 
Thursday night we had the President yelling at us for an hour, 
sounding like it was 1941, with threats to democracy around the 
world. Yesterday we got his budget. He seemed more like Harry 
Truman in the 1940's or Bill Clinton in 1993, drawing down our 
military after the wars. It only had a 1 percent increase in 
defense spending compared to last year's request. Given 
continued high inflation, that amounts to a real cut. China 
recently announced that it was going to increase its defense 
budget by 7.2 percent.
    Do you think the President's Budget Request accurately and 
soundly addresses the severity of the threats that we face 
today?
    Dr. Brands. No. I worry both about the topline, and then 
from what I can tell from a quick skim of the budget 
submission, particularly what it will mean for procurement in 
the coming years, where I think we are looking at an absolute 
cut, which would be, even in relative, inflation-adjusted 
terms, more severe still.
    Senator Cotton. Could you tell us a little bit more about 
the specific concerns you have on procurement, going forward in 
the future?
    Dr. Brands. Well, one of the major challenges we face at 
this point is generating and procuring the number of munitions 
we would need for particular contingencies as well as simply 
some of the platforms that would be used to deliver them. It is 
helpful to have investment in R&D, in modernization and things 
that look forward down the future. But you are not going to be 
able to get there unless you have the money to actually buy 
things once they become available.
    Moreover, procurement spending at this point provides a 
double benefit, because the only way you can really strengthen 
the defense industrial base is by providing guarantees that 
money to buy things will actually be there. If you are looking 
for firms to expand or ramp up new production lines, invest in 
a new workforce. That is the sort of money you need to be 
spending now that would make possible further investments down 
the road.
    Senator Cotton. A kind of multi-year procurement authority, 
that some in Congress have resisted.
    Dr. Brands. Yes, I think that is going to be critical.
    Senator Cotton. Yes. That is because you cannot expect 
those companies, or more to the point, the companies' owners in 
the form of their shareholders, to lay out significant capital 
up front if they do not have confidence of a return down the 
road?
    Dr. Brands. If the business case is there, then they will 
make the investments. But for the business case to be there 
they have to be persuaded that this is not just a 1-year bump 
in, say, procurement of 155 mm artillery ammunition, or 
whatever the capability is. Because otherwise they cannot 
justify all the new investments that will be necessary to get 
to that point.
    Senator Cotton. Dr. Scharre, you are nodding your head. Do 
you have anything to add to that?
    Dr. Scharre. I do, and I guess I would add, Senator, that, 
you know, we have heard from lots of experts in Government, 
outside of Government I have talked to, Dr. Brands, of course, 
has written extensively on this, that we are entering this 
dangerous window at the end of the decade with China.
    It seems to me that if we believed that we would be putting 
our Defense Department, our defense industry on a wartime 
footing. We would be expanding capacity. We would be increasing 
our defense industrial base capacity, building our munitions 
stockpiles, building our ability to surge. We have a few years 
of critical warning now, and we need to seize that opportunity, 
or I think there is a very real risk that we look back on this 
moment and realize that we missed the opportunity to be ready.
    Senator Cotton. Yes. So you make those outlays now, and you 
want to ensure companies will get a reasonable rate of return 
on their investments now. Is there any reason to think the 
world is going to be safer in 3 or 5 or 10 years than it is 
now, and we will not need all that stuff we are investing in? 
Dr. Brands, do you want to take that?
    Dr. Brands. No, there is no reason to believe that. We are 
going to be dealing with a hyper-revisionist and perhaps hyper-
mobilized Russia for some time to come. We are going to be 
dealing with a China whose military buildup continues at a very 
alarming rate. We are going to be dealing with a North Korea 
whose nuclear arsenal and missile arsenal is going to outpace 
United States missile defenses at some point this decade, as 
well as all the challenges in Iran and from terrorist groups. 
So no, there is no reason to think the threat environment will 
become less severe.
    Senator Cotton. Dr. Scharre?
    Dr. Scharre. I might just add that the best thing that we 
could do to buy down the risk of a conflict with China is to 
make investments now that increase deterrence.
    Senator Cotton. It is always costly, investment of 
resources and national effort, to preserve the peace, but more 
costly, I presume, to win a war when the peace is not 
preserved.
    Thank you, gentleman.
    Chairman Reed. Thank you very much, Senator Cotton. 
Gentleman, thank you for excellent testimony, and I hope that 
this will not be the last time we have you before the Committee 
and reach out for advice, and I encourage you to feel free, 
please, to let us know what your thoughts are and what we 
should be thinking about.
    We are hopeful that having passed the last batch of 
appropriations bills will get the defense bill done next week, 
but if not then we have problems, immediate problems.
    But again, let me thank you all for excellent testimony and 
for your continued wise insights into the national security of 
the United States.
    With that I will adjourn the hearing.
    [Whereupon, at 10:47 a.m., the Committee adjourned.]

            Questions Submitted by Senator Elizabeth Warren
                 blast overpressure and blast exposure
    1. Senator Warren. Dr. Scharre, you published a Center for New 
American Security report in 2018 on the impact of blast overpressure on 
servicemembers. What steps do you think the Department of Defense (DOD) 
should take now to improve how it is protecting servicemembers from 
blast overpressure and blast exposure?
    Dr. Scharre. DOD has taken some steps to improve its understanding 
of the effects of blast overpressure on the brain but significant work 
remains.\1\ Most notably, DOD has yet to implement a comprehensive 
blast surveillance program that would collect blast exposure data for 
all servicemembers at risk of blast exposure in training and combat. 
The basic technology to collect this data in a quantitative, automated, 
and cost-effective manner has existed since 2011 and have been deployed 
on servicemembers in combat zones. DOD has undertaken a pilot program 
(Blast Overpressure Studies--Pilot) but has not yet implemented a 
comprehensive blast surveillance program that would cover all troops 
who are at risk of blast exposure in training and combat.

Military Occupational Blasts: An Overview of the Research, Critical

    This failure has significant consequences for troops today and over 
the long term. In the immediate term, U.S. troops are denied the 
opportunity to change their firing tactics based on feedback from blast 
gauges that report their amount of blast exposure. The DOD CONQUER 
program found that that troops were able to reduce blast pressure 
exposure by 30 to 90 percent by modifying firing tactics, but they 
cannot do so without the feedback that blast gauges provide.\2\ In long 
term, without blast exposure data in their service records, troops may 
be denied care for traumatic brain injury by the DOD and VA. Finally, a 
failure to collect comprehensive data on blast exposure makes it more 
difficult for DOD to gain the necessary information to understand the 
relationship between blast exposure and potential brain injury. The 
first step toward better understanding and mitigating potential harm 
from blast exposure is to collect the data.

Overpressure Exposure During Training by Adjustment of Body Position as

usad429/7422180.

    2. Senator Warren. Dr. Scharre, which military occupational 
specialties are at highest risk for blast overpressure and blast 
exposure?
    Dr. Scharre. The unfortunate reality is that we do not have good, 
quantitative data to assess which military occupational specialties are 
most at risk from blast exposure because DOD has not collected this 
data. The 4 November 2022 memo from Assistant Secretary of Defense for 
Readiness Shawn G. Skelly, ``Interim Guidance for Managing Brain Health 
Risk from Blast Overpressure,'' identified several weapon systems whose 
blast overpressure exceeds 4 pounds per square inch (psi). Troops 
exposed to blast overpressure in excess of 4 psi have demonstrated 
degradation in neurocognitive performance. Weapon systems identified in 
the memorandum include breaching explosives, shoulder-fired anti-tank 
weapons, 0.50 caliber sniper rifles and machine guns, howitzers, and 
mortars. Troops who regularly use these weapon systems, such as those 
in breaching, artillery, mortars, anti-tank, or sniper duty positions, 
may be at heightened risk. However, to more fully understand the risk 
profile of troops in various roles, DOD must take several additional 
steps:
      Undertake additional weapons testing using blast pressure 
monitoring devices (blast gauges) to better characterize the blast 
effects of these weapons.
      Conduct computer simulations of how the blast waves 
travel to estimate the actual amount of blast overpressure exposure to 
the brain.
      Conduct neurocognitive testing of troops before and after 
firing to understand the immediate neurocognitive effects from blast 
exposure when firing weapons.
      Conduct a longitudinal medical study of troops in high-
risk occupations or duty positions to better understand the cumulative 
effects of repeated exposures over the course of a servicemember's 
career.
      Institute a blast surveillance program to comprehensively 
monitor and record blast exposures across the force to better 
understand how many exposures, of what intensity and over what 
duration, troops are experiencing in training and combat.
    DOD has taken some of these actions but has not pursued all of them 
comprehensively. For example, the DOD CONQUER program was a pilot blast 
monitoring program to better characterize training-related blast 
exposure for servicemembers using breaching explosives, shoulder-fired 
anti-tank weapons, artillery, mortars, and .50 caliber machine guns and 
sniper rifles. This data has helped improve understanding of the type 
of blast exposure caused by firing various weapon systems. Similarly, 
DOD has conducted a pilot blast surveillance program (Blast 
Overpressure Studies--Pilot). However, there is much more that needs to 
be learned about the effects of repetitive blast exposure on the brain. 
Gaining this information will help DOD better understand which duty 
positions are most at risk and ultimately establish training safety 
standards that will reduce risk to servicemembers while preserving 
readiness.

    3. Senator Warren. Dr. Scharre, what would be the benefits of the 
Department of Defense updating and disseminating thresholds for blast 
exposure safety, including on the basis of brain injury risk and over 
longer periods of time such as 72 to 96 hours, yearly, and annual 
limits?
    Dr. Scharre. The benefit would be to improve safety standards, 
adjust training practices, and ultimately reduce the amount of 
potentially harmful exposure that U.S. troops have to blasts, including 
from firing their own weapons. The long-term effect of reducing blast 
exposure to safer levels would be reduced incidents and severity of 
traumatic brain injury among the force, increasing long-term health, 
reducing cognitive impairments, and improving readiness.

    4. Senator Warren. Dr. Scharre, what would be the benefits of the 
Department of Defense developing strategies to mitigate blast exposure 
and blast overpressure to the military occupational specialties most at 
risk?
    Dr. Scharre. There are several potential strategies that DOD could 
employ to reduce potentially harmful blast exposure to safer limits. 
One of the easiest ways to do so is to provide blast gauges to troops 
when firing heavy weapons or conducting breaching, which provides 
immediate feedback on blast overpressure exposure. In prior tests using 
blast gauges during training, the feedback from blast gauges allowed 
units to identify flaws in firing positions that cause individuals to 
receive excessive amounts of exposure, such as standing in the wrong 
location or having the wrong body position when firing the weapon. 
Feedback from blast gauges allows troops to immediately modify their 
firing techniques to reduce exposure. The DOD CONQUER program found 
that that troops were able to reduce blast pressure exposure by 30 to 
90 percent by modifying firing tactics.\3\ Other strategies to reduce 
blast exposure could include reducing the number of rounds that 
servicemembers are exposed to during training, requiring mandatory rest 
periods after exposures to allow the brain to heal, mandating greater 
standoff for non-firing troops on firing ranges, increasing protection 
such as through improved helmet designs that could reduce blast 
exposure, limiting the total amount of time in their career that 
servicemembers can spend in high-risk duty positions, such as anti-tank 
roles that involve firing shoulder-fired heavy weapons, and potentially 
modifying certain weapons to reduce the amount of blast overpressure 
exposure when firing. The benefit of these and potentially other 
strategies would be to reduce potentially harmful blast exposure and, 
as a result, reduce incidents of brain injury while minimizing the 
impact to training and operational effectiveness.

Exposure During Training by Adjustment of Body Position as Demonstrated 
With Field Data.''

    5. Senator Warren. Dr. Scharre, how would servicemembers benefit if 
the Department of Defense establishes blast exposure and traumatic 
brain injury logs to track their exposure over their career?
    Dr. Scharre. I have personally spoken with multiple servicemembers 
who were exposed to excessive amounts of blasts from firing their own 
weapons during training well beyond approved limits, particularly the 
Carl Gustaf recoilless rifle, and now suffer traumatic brain injury as 
a result. However, since this exposure is not documented in their 
service records and the VA and DOD have been slow to acknowledge the 
link between blast exposure and brain injury, these servicemembers have 
struggled to receive care through the VA for their injuries.

    6. Senator Warren. Dr. Scharre, what would be the benefits of 
requiring DOD to consider blast exposure in the weapons acquisition 
process and for companies to provide blast overpressure and blast 
exposure safety data under their contract requirements?
    Dr. Scharre. DOD currently lacks good data on the amount of blast 
overpressure that certain weapons may expose troops to when firing. 
Collecting this data is essential to understanding the relationship 
between blast exposure and brain injury and establishing safe limits 
and blast exposure reduction strategies. DOD will not be able to fully 
understand and mitigate potentially harmful blast exposure--or even 
understand what levels and types of blast exposure are potentially 
harmful--without first collecting the data.

    7. Senator Warren. Dr. Scharre, what steps should the Department 
take to mitigate the higher risk levels to blast exposure and blast 
overpressure that training instructors face?
    Dr. Scharre. DOD should take several steps to mitigate blast 
exposure for training instructors:
      Issue blast gauges to instructors so that they can modify 
their positions on the range to minimize their blast exposure based on 
immediate, quantitative feedback on blast exposure.
      Enroll instructors in a blast surveillance program to 
record their cumulative blast exposures over time.
      Conduct regular neurocognitive assessments of training 
instructors, including pre-and post-training events, to identify and 
document any changes in performance.
      Continue to update range safety standards based on the 
best available data from ongoing DOD studies on blast exposure.

    8. Senator Warren. Dr. Scharre, New York Times reporting from 
November 2023 revealed that despite DOD taking some steps to improve 
safety for blast overpressure, ``things have hardly changed on the 
ground.'' Instead, ``[t]raining continues largely as it did before'' 
and ``[t]roops say they see little being done to limit or track blast 
exposure.'' What are the biggest challenges to implementing safety 
measures for mitigating exposure on the ground?
    Dr. Scharre. The biggest obstacle to improving safety measures for 
mitigating blast exposure is the failure of DOD leaders to prioritize 
understanding and mitigating harm from blast exposure. DOD has 
generated presentations, briefings, documents, and some modest pilot 
programs but taken few meaningful steps since our CNAS report was 
published in 2018. DOD has not implemented a comprehensive blast 
surveillance program that would track and monitor blast exposure among 
servicemembers in training and combat. DOD has not actually implemented 
a longitudinal medical study that would collect data on blast 
exposures, neurocognitive performance, and potential biomarkers on 
high-risk servicemembers who are exposed to blasts over the course of 
their career so that DOD can better understand the effects of 
cumulative blast exposures over time.
    These failures cannot be chalked up to merely a slow-moving 
bureaucracy. They represent a failure of DOD leaders to prioritize this 
issue and take meaningful and urgent action to mitigate the potential 
harm to servicemembers from blast exposure.

    9. Senator Warren. Dr. Scharre, what steps should the Department 
take to improve training and education for servicemembers on the 
dangers of this exposure and safety measure to address these concerns, 
and ensure that servicemembers are following through on implementation 
of these safety measures?
    Dr. Scharre. DOD has ample mechanisms to ensure that troops comply 
with safety standards and conduct hazardous training in a safe manner. 
For example, DOD regularly conducts training on airborne operations and 
has extensive procedures in place to ensure that troops successfully 
train on high-risk activities in a safe manner. DOD is more than 
capable of enforcing training safety standards for firing heavy 
weapons, such as firing limits, if it prioritizes doing so.

               Questions Submitted by Senator Jacky Rosen
                           technological edge
    10. Senator Rosen. Dr. Scharre, history shows us that harnessing 
new technologies creates a significant advantage on the battlefield. 
The country that manages to use these technologies effectively and 
efficiently will have the upper hand in any future wars. What do you 
predict will be the defining weapons of the next war and how can the 
United States ensure it uses these weapons effectively and responsibly?
    Dr. Scharre. Technology is critical to modern warfighting, and 
disruptive technologies have often led to profound changes in the 
character of warfare, necessitating changes in tactics, doctrine, and 
military organization. In recent years, the Defense Department has 
identified priority technology areas for investment that may have a 
significant effect on U.S. and adversary warfighting capabilities. What 
is often missing from DOD lists of technology areas is prioritization 
among these technologies and a sense of the relative speed at which 
these technologies are advancing. Technologies are advancing at 
dramatically different rates of progress. In particular, information 
technologies are currently growing at literal exponential rates. This 
creates opportunities for significant disruptions in warfare from 
military capabilities that leverage information technologies.
    A few examples of the current exponential growth trends in 
information technology:
    Global communications networks are growing exponentially in speed 
and size. From 2018 to 2023, broadband speeds grew 20 percent annually 
and wireless network speeds 27 percent annually. During that same time, 
the number of Internet of Things (IoT) devices grew 20 percent per year 
and the number of global public Wi-Fi hotspots 30 percent annually. As 
of 2023, two-thirds of the world's population was online and there were 
nearly 30 billion connected devices.\4\ While militaries will operate 
military-specific networks on the battlefield, the same underlying 
technological advancements that enable exponential growth in civilian 
network bandwidth and connectivity also enable military networks.

---------------------------------------------------------------------------
    Artificial intelligence capabilities are similarly growing 
exponentially. The amount of data and computational power applied to 
cutting-edge machine learning systems is growing at a breathtaking 
pace. Between 2010 and 2022, the amount of computational power used to 
train cutting-edge machine learning models increased ten 
billionfold.\5\ The amount of computing power used to train the largest 
and most capable AI models is currently doubling every 7 months.\6\ 
Chip performance is doubling approximately every 2 years.\7\ And 
algorithms are also improving, doubling in performance approximately 
every 9 months.\8\ The combined effect of these exponential growth 
trends is such that by 2030, the most capable AI models could be 
trained on one million times more effective computing power than 
today.\9\

    With the digitization of biology, genomics is also benefiting from 
exponential growth in information technology. It cost $300 million to 
sequence the first human genome, which was completed in 2000.\10\ By 
2023, the cost to sequence a human genome had dropped to $200, over a 
million times cheaper,\11\ allowing scientists to build massive genomic 
data bases.\12\ AI models can predict biochemical interactions, such as 
how proteins fold,\13\ enabling scientists to computationally explore 
hundreds of millions of possibilities, including those not found in 
nature.\14\ The price of DNA synthesis machines, which allow scientists 
to manufacture artificial proteins, is dramatically dropping.\15\ And 
automated labs use information technology to accelerate the speed and 
scale of physical experimentation in biology.\16\

    Military capabilities enabled by information technology riding 
these exponential curves are the most likely to see dramatic changes in 
the coming decades. These include capabilities relying on autonomy, 
robotics, advanced sensors, communications networks, data processing, 
automated decision aids, AI and machine learning, computing hardware, 
cloud computing, electronic warfare, cyber operations, synthetic 
biology, and genomics. While other non-digital military capabilities 
will continue to be valuable, they are often not growing at the same 
pace, and are therefore unlikely to see the same degree of change. 
Missiles are not ten billion times faster than they were in 2010. 
Stealth aircraft are not ten billion times stealthier. Yet information 
technologies are advancing at a breathtaking pace, creating new 
opportunities for military applications.
    The war in Ukraine provides an example of this dynamic. The 
conflict is a blend of War War I style trench and artillery warfare, 
combined with 21st century drones and social media. Yet the most 
dramatic changes are happening in the evolution of drone technology and 
tactics. Drones are increasingly adopting AI tools to identify targets 
and autonomous capabilities to carry out attacks in the face of 
electronic warfare countermeasures and jamming. Counter-drone systems 
have led to a rapid cycle of innovation in drones and countermeasures. 
This pace of adaptation is not matched, for example, in trench 
construction.
    If the United States is to be prepared for future conflicts, it 
must remain at the forefront of rapidly evolving digital technologies 
or risk falling behind competitors. In addition to their rapid growth, 
many information technologies come from the commercial sector and are 
highly globalized, making them widely available, including to State and 
non-State competitors.

    11. Senator Rosen. Dr. Scharre, new technologies depend on a 
fragile and global supply chain--from critical minerals to 
semiconductors. Access to raw and refined critical minerals will have a 
role to play in these technologies, but only if we make a concerted 
effort to strategically leverage our resource advantages to overcome 
global supply chain challenges. What specific strategies can the United 
States employ to mitigate such vulnerabilities, invest in domestic 
industry, and help strengthen our supply chain resilience?
    Dr. Scharre. For many years, China has held an advantage in both 
the mining of rare earth minerals and their processing. Thanks to 
discoveries of large deposits off the coast of Japan,\17\ in 
Sweden,\18\ and in Wyoming, \19\ the United States and its allies have 
an opportunity loosen China's stranglehold on mining. The United States 
and its allies should also work to reduce their reliance on China for 
rare earth mineral processing. The United States should invest in 
storage capacity for processed versions of these minerals and maintain 
a strategic reserve to reduce the ability for China to use rare earth 
minerals as leverage as it did to Japan in 2010.\20\ The United States 
should work with its allies to develop the deposits that have been 
discovered in the United States and partner nations to reduce reliance 
on Chinese mining. Reducing China's advantage in processing will be 
more difficult due to both their edge in the technology \21\ and their 
lax environmental standards.\22\ The United States needs to build on 
its funding of new processing plants through the Defense Production Act 
\23\ and create additional incentives for companies to invest in and 
open processing facilities.

                             staying ahead
    12. Senator Rosen. Dr. Scharre, what are the competitive advantages 
of the United States in comparison to China when it comes to artificial 
intelligence (AI)? How can the United States ensure that our public and 
private institutions stay ahead of the curve in this critically 
important field?
    Dr. Scharre. The United States has two asymmetric advantages over 
China in AI: chips and human talent.
    U.S. companies occupy critical chokepoints in the supply chain for 
manufacturing high-end chips, especially in the electronic design 
automation software used to manufacture advanced chips. Collectively, 
the United States, Japan, and the Netherlands control 90 percent of the 
global market for semiconductor manufacturing equipment. The United 
States has used this leverage, in concert with Japan and the 
Netherlands, to deny China access to leading-edge AI chips by 
prohibiting the export to China of any advanced chips made using United 
States technology. Given the dominance of U.S. companies in 
semiconductor manufacturing equipment chokepoints, United States export 
controls have, in the near term, successfully denied China access to 
the cutting-edge AI chips used to train the largest and most capable AI 
models. To fully capitalize on this advantage, however, the United 
States must take several additional steps.
    First, in the near term, the United States must extend protections 
on high-end chips to include other aspects of the supply chain for the 
computation used to train cutting-edge AI models. This includes 
regulations on cloud providers and trained AI models with certain dual-
use capabilities, such as the ability to aid in cyber, chemical, or 
biological attacks. Restrictions on cloud computing infrastructure and 
trained AI models need not be as broad as the current chip export 
controls. Cloud computing infrastructure, for example, provides the 
opportunity for more tailored and fine-grained restrictions, since the 
chips themselves remain in the United States.\24\ Similarly, the 
overwhelming majority of AI models are safe to release open source. 
However, a small set of the most computationally intensive AI models, 
which can only be trained using the most advanced, export-controlled AI 
chips, may need to be export controlled.\25\ Without additional 
controls on cloud computing infrastructure and trained AI models, U.S. 
chip export controls will not be effective. China can simply access 
chips through the cloud. Or Chinese AI labs can download trained United 
States AI models for free, such as Meta's Llama 2 model, negating the 
need to train their own large models from scratch, effectively 
circumventing United States export controls.

---------------------------------------------------------------------------
    Second, the United States must take steps now to preserve its 
control over key chokepoints in semiconductor manufacturing equipment, 
so that the United States retains the ability to deny China access to 
advanced chips in the future. United States leverage over China's 
access to advanced AI chips stems from the dominant role that United 
States companies play in semiconductor manufacturing equipment, 
especially in the electronic design automation software used to design 
the most advanced chips. A major focus for the CHIPS Act should be 
ensuring that U.S. companies remain in a dominant position in these key 
chokepoints for the next generation of chip manufacturing technology. 
The United States can help achieve this by supporting research and 
development in next-generation semiconductor manufacturing technology. 
Additionally, building leading-edge fabs in the United States can help 
create a vibrant ecosystem of chip manufacturers, designers, and 
equipment suppliers--and the human talent that supports those 
innovations--in the United States.
    The United States also has significant advantages over China in 
human talent. China produces more of the world's top AI scientists than 
any other country, but they don't stay in China--they come to the 
United States.\26\ Over half of China's top undergraduates studying AI 
come to the United States for their graduate studies.\27\ And 90 
percent of Chinese undergraduates who gain a PhD in AI in the United 
States stay in the United States after graduation.\28\ China's brain 
drain is a brain gain for the United States. China has engaged in a 
massive campaign of intellectual property theft and academic espionage, 
including by tapping into the global diaspora of Chinese scientists and 
engineers. The United States must improve research security, visa 
screening, and investigations to crack down on academic espionage. But 
the United States Government should not cutoff the flow of Chinese 
talent to the United States, which overwhelmingly benefits the United 
States over China.

    13. Senator Rosen. Dr. Scharre, over 66 years ago, in response to 
the launch of the Soviet satellite Sputnik, Congress passed the 
National Defense Education Act, which became a successful legislative 
investment in higher education. You have argued that ``talent'' is 
going to be one of the important cornerstones to dominate the future, 
but it seems like it may take a Sputnik-like moment to motivate us to 
make such large changes. With the speed at which technology evolves, 
will we be too late when that moment comes, and how do we attract the 
right people today to prepare for tomorrow?
    Dr. Scharre. Our Sputnik moment for AI is here. ChatGPT and 
subsequent breakthroughs set off a wave of excitement, investment, and 
government attention on AI in the United States, China, and around the 
world. The question is whether we choose to rise to this moment.
    The United States has many advantages in the competition for 
talent. Seven of the top ten institutions publishing deep learning 
research are American universities or corporate research labs. Only two 
are Chinese.\29\ Yet these advantages will not be enough to secure 
continued American leadership in AI. The United States must reinvest in 
human talent through improved STEM education and high-skilled 
immigration if it is to remain a global technology leader. \30\

    Educators and students also need the resources to leverage AI tools

(NAIRR), if fully funded by Congress, will be able to provide much-
needed data and computing resources for under-resourced STEM 
departments. \32\ Additionally, recent changes to STEM education should

underserved communities, and increase science-themed organizations for 
children. \33\

    Improvements in domestic STEM education, while necessary to sustain 
America's long-term competitive edge in science and technology, will 
also take time to fully come to fruition. The foundations for science 
and technology education begin early, and it will take a generation to 
fully reap the benefits of reformed STEM education. This places a 
premium on improving STEM education now. But these steps will also not 
be enough.
    High-skilled immigration, by contrast, can bring skilled scientists 
and engineers immediately into the United States, injecting much-needed 
talent into America's workforce. More fundamentally, as a nation of 330 
million people, the United States will always be at a disadvantage 
competing against China's 1.4 billion if the United States restricts 
itself to home-grown talent.\34\ Yet America has an asymmetric 
advantage over China in the talent competition: American universities 
and companies are a major draw for AI researchers from around the 
world. Indeed, American leadership in AI is already heavily powered by 
foreign talent. Two-thirds of the top AI researchers in the United 
States did their undergraduate studies overseas, with the top sending 
regions China, India, and Europe.\35\ If the United States draws on the 
best and brightest of the world's 8 billion people, the United States 
will be able to maintain a leadership position over China in AI talent. 
Yet America's biggest barrier to AI talent is its own immigration 
policies.

    The Biden administration has taken some steps to make it easier for 
international STEM students to come to the United States. \40\ The 
White House has, for example, increased the number of foreign exchange 
programs, expanded the number of fields qualifying for the STEM 
Optional Practical Training (OPT) visa for recent college graduates, 
and updated policies on the evidence STEM PhDs can present when 
applying for the O-1A ``extraordinary ability'' visa. These are 
valuable steps but have a minor impact relative to the scale of self-
imposed barriers to talent. The United States needs comprehensive 
reform of high-skilled immigration policy to make it easier for U.S. 
universities and companies to recruit international scientists and 
engineers. This should include reducing barriers for STEM PhD graduates 
to stay in the United States by exempting them from the H-1B cap and 
easing the path to permanent residency. \41\

    14. Senator Rosen. Dr. Brands, you have argued for the enduring 
importance of the Middle East to United States foreign policy and the 
challenges posed by Iran. What key elements should be included in a 
reassessment of United States strategy toward Iran to address its 
nuclear ambitions, regional aspirations, and warfare via terrorist 
proxies?
    Dr. Brands. Regardless of what happens in the current Middle East 
crisis, the United States will face an expanded challenge from an Iran 
whose nuclear program continues to advance and whose foreign legion of 
proxies has become far more potent than many American observers had 
expected. In any reassessment of United States strategy in the region, 
the United States will need to reestablish redlines beyond which 
further progress toward a nuclear capability would bring a swift and 
dramatic response, which will, in turn, require establishing more 
credible threats to use force against Iran's nuclear program and its 
accompanying military capabiliies. It will also need to develop a 
strategy that inflicts higher costs on Iran for the actions of the 
proxies it has empowered. It is not sustainable, for instance, for the 
US to be playing defense in the Red Sea and Gulf of Aden against Huthi 
attacks, while taking no action against the Iranian naval assets that 
are assisting those attacks with intelligence and other support. Only 
when Tehran becomes convinced that it will pay a major price for 
actions of its proxies will it move to distance itself from them or 
restrain them. Finally, any strategy in the region must be accompanied 
by a strengthening of United States ties with key regional players, in 
the Gulf and beyond, that are most likely to join Washington in pushing 
back against Iranian influence.
