Backing into World War III

 Foreign Policy
Robert Kagan
Think
 of two significant trend lines in the world today. One is the 
increasing ambition and activism of the two great revisionist powers, 
Russia and China. The other is the declining confidence, capacity, and 
will of the democratic world, and especially of the United States, to 
maintain the dominant position it has held in the international system 
since 1945. As those two lines move closer, as the declining will and 
capacity of the United States and its allies to maintain the present 
world order meet the increasing desire and capacity of the revisionist 
powers to change it, we will reach the moment at which the existing 
order collapses and the world descends into a phase of brutal anarchy, 
as it has three times in the past two centuries. The cost of that 
descent, in lives and treasure, in lost freedoms and lost hope, will be 
staggering. 
Americans
 tend to take the fundamental stability of the international order for 
granted, even while complaining about the burden the United States 
carries in preserving that stability. History shows that world orders do
 collapse, however, and when they do it is often unexpected, rapid, and 
violent. The late 18th century was the high point of the Enlightenment 
in Europe, before the continent fell suddenly into the abyss of the 
Napoleonic Wars. In the first decade of the 20th century, the world’s 
smartest minds predicted an end to great-power conflict as revolutions 
in communication and transportation knit economies and people closer 
together. The most devastating war in history came four years later. The
 apparent calm of the postwar 1920s became the crisis-ridden 1930s and 
then another world war. Where exactly we are in this classic scenario 
today, how close the trend lines are to that intersection point is, as 
always, impossible to know. Are we three years away from a global 
crisis, or 15? That we are somewhere on that path, however, is 
unmistakable.
Are we three years away from a global crisis, or 15?
And
 while it is too soon to know what effect Donald Trump’s presidency will
 have on these trends, early signs suggest that the new administration 
is more likely to hasten us toward crisis than slow or reverse these 
trends. The further accommodation of Russia can only embolden Vladimir 
Putin, and the tough talk with China will likely lead Beijing to test 
the new administration’s resolve militarily. Whether the president is 
ready for such a confrontation is entirely unclear. For the moment, he 
seems not to have thought much about the future ramifications of his 
rhetoric and his actions.
China
 and Russia are classic revisionist powers. Although both have never 
enjoyed greater security from foreign powers than they do today—Russia 
from its traditional enemies to the west, China from its traditional 
enemy in the east—they are dissatisfied with the current global 
configuration of power. Both seek to restore the hegemonic dominance 
they once enjoyed in their respective regions. For China, that means 
dominance of East Asia, with countries like Japan, South Korea, and the 
nations of Southeast Asia both acquiescing to Beijing’s will and acting 
in conformity with China’s strategic, economic, and political 
preferences. That includes American influence withdrawn to the eastern 
Pacific, behind the Hawaiian Islands. For Russia, it means hegemonic 
influence in Central and Eastern Europe and Central Asia, which Moscow 
has traditionally regarded as either part of its empire or part of its 
sphere of influence. Both Beijing and Moscow seek to redress what they 
regard as an unfair distribution of power, influence, and honor in the 
U.S.-led postwar global order. As autocracies, both feel threatened by 
the dominant democratic powers in the international system and by the 
democracies on their borders. Both regard the United States as the 
principal obstacle to their ambitions, and therefore both seek to weaken
 the American-led international security order that stands in the way of
 their achieving what they regard as their rightful destinies.
IT WAS GOOD WHILE IT LASTED
Until
 fairly recently, Russia and China have faced considerable, almost 
insuperable, obstacles in achieving their objectives. The chief obstacle
 has been the power and coherence of the international order itself and 
its principal promoter and defender. The American-led system of 
political and military alliances, especially in the two critical regions
 of Europe and East Asia, has presented China and Russia with what Dean 
Acheson once referred to as “situations of strength”
 that have required them to pursue their ambitions cautiously and, since
 the end of the Cold War, to defer serious efforts to disrupt the 
international system.
The
 system has checked their ambitions in both positive and negative 
ways. During the era of American primacy, China and Russia have 
participated in and for the most part been beneficiaries of the open 
international economic system the United States created and helps 
sustain; so long as that system functions, they have had more to gain by
 playing in it than by challenging and overturning it. The political and
 strategic aspects of the order, however, have worked to their 
detriment. The growth and vibrancy of democratic government in the two 
decades following the collapse of Soviet communism posed a continual 
threat to the ability of rulers in Beijing and Moscow to maintain 
control, and since the end of the Cold War they have regarded every 
advance of democratic institutions—especially the geographical advance 
of liberal democracies close to their borders—as an existential threat. 
That’s for good reason: Autocratic powers since the days of Klemens von 
Metternich have always feared the contagion of liberalism. The mere 
existence of democracies on their borders, the global free flow of 
information they cannot control, the dangerous connection between free 
market capitalism and political freedom—all pose a threat to rulers who 
depend on keeping restive forces in their own countries in check. 
The 
continual challenge to the legitimacy of their rule posed by the 
U.S.-supported democratic order has therefore naturally made them 
hostile both to that order and to the United States. But, until 
recently, a preponderance of domestic and international forces has 
dissuaded them from confronting the order directly. Chinese rulers have 
had to worry about what an unsuccessful confrontation with the United 
States might do to their legitimacy at home. Even Putin has pushed only 
against open doors, as in Syria, where the United States responded 
passively to his probes. He has been more cautious when confronted by 
even marginal U.S. and European opposition, as in Ukraine.
During
 the era of American primacy, China and Russia have participated in and 
for the most part been beneficiaries of the open international economic 
system the United States created and helps sustain; so long as that 
system functions, they have had more to gain by playing in it than by 
challenging and overturning it.
The
 greatest check on Chinese and Russian ambitions has been the military 
and economic power of the United States and its allies in Europe and 
Asia. China, although increasingly powerful, has had to contemplate 
facing the combined military and economic strength of the world’s 
superpower and some very formidable regional powers linked by alliance 
or common strategic interest—including Japan, India, and South Korea, as
 well as smaller but still potent nations like Vietnam and Australia. 
Russia has had to face the United States and its NATO allies. When 
united, these U.S.-led alliances present a daunting challenge to a 
revisionist power that can call on few allies of its own for assistance.
 Even were the Chinese to score an early victory in a conflict, such as 
the military subjection of Taiwan or a naval battle in the South or East
 China Sea, they would have to contend over time with the combined 
industrial productive capacities of some of the world’s richest and most
 technologically advanced nations and the likely cutoff of access to 
foreign markets on which their own economy depends. A weaker Russia, 
with its depleted population and oil- and gas-dependent economy, would 
face an even greater challenge.
For
 decades, the strong global position enjoyed by the United States and 
its allies has discouraged any serious challenge. So long as the United 
States was perceived as a dependable ally, Chinese and Russian leaders 
feared that aggressive moves would backfire and possibly bring their 
regimes down. This is what the political scientist William Wohlforth 
once described as the inherent stability of the unipolar order:
 As dissatisfied regional powers sought to challenge the status quo, 
their alarmed neighbors turned to the distant American superpower to 
contain their ambitions. And it worked. The United States stepped up, 
and Russia and China largely backed down—or were preempted before acting
 at all.
Faced
 with these obstacles, the best option for the two revisionist great 
powers has always been to hope for or, if possible, engineer a weakening
 of the U.S.-supported world order from within, either by separating the
 United States from its allies or by raising doubts about the U.S. 
commitment and thereby encouraging would-be allies and partners to forgo
 the strategic protection of the liberal world order and seek 
accommodation with its challengers.
The
 present system has therefore depended not only on American power but on
 coherence and unity at the heart of the democratic world. The United 
States has had to play its part as the principal guarantor of the order,
 especially in the military and strategic realm, but the order’s 
ideological and economic core—the democracies of Europe and East Asia 
and the Pacific—has also had to remain relatively healthy and confident.
In
 recent years, both pillars have been shaken. The democratic order has 
weakened and fractured at its core. Difficult economic conditions, the 
recrudescence of nationalism and tribalism, weak and uncertain political
 leadership and unresponsive mainstream political parties, and a new era
 of communications that seems to strengthen rather than weaken tribalism
 have together produced a crisis of confidence not only in the 
democracies but in what might be called the liberal enlightenment 
project. That project elevated universal principles of individual rights
 and common humanity over ethnic, racial, religious, national, or tribal
 differences. It looked to a growing economic interdependence to create 
common interests across boundaries and to the establishment of 
international institutions to smooth differences and facilitate 
cooperation among nations. Instead, the past decade has seen the rise of
 tribalism and nationalism, an increasing focus on the Other in all 
societies, and a loss of confidence in government, in the capitalist 
system, and in democracy. We are witnessing the opposite of Francis 
Fukuyama’s “end of history.” History is returning with a vengeance and 
with it all the darker aspects of the human soul, including, for many, 
the perennial human yearning for a strong leader to provide firm 
guidance in a time of confusion and incoherence.
THE DARK AGES 2.0
This
 crisis of the enlightenment project may have been inevitable, a 
recurring phenomenon produced by inherent flaws in both capitalism and 
democracy. In the 1930s, economic crisis and rising nationalism led many
 to doubt whether either democracy or capitalism was preferable to 
alternatives such as fascism and communism. And it is no coincidence 
that the crisis of confidence in liberalism accompanied a simultaneous 
breakdown of the strategic order. Then, the question was whether the 
United States as the outside power would step in and save or remake an 
order that Britain and France were no longer able or willing to sustain.
 Now, the question is whether the United States is willing to continue 
upholding the order that it created and which depends entirely on 
American power or whether Americans are prepared to take the risk—if 
they even understand the risk—of letting the order collapse into chaos 
and conflict.
That
 willingness has been in doubt for some time, well before the election 
of Trump and even before the election of Barack Obama. Increasingly in 
the quarter century after the end of the Cold War, Americans have been 
wondering why they bear such an unusual and outsized responsibility for 
preserving global order when their own interests are not always clearly 
served—and when the United States seems to be making all the sacrifices 
while others benefit. Few remember the reasons why the United States 
took on this abnormal role after the calamitous two world wars of the 
20th century. 
The millennial generation born after the end of the Cold 
War can hardly be expected to understand the lasting significance of the
 political, economic, and security structures established after World 
War II. Nor are they likely to learn much about it in high school and 
college textbooks obsessed with noting the evils and follies of American
 “imperialism.” Both the crises of the first half of the 20th century 
and its solution in 1945 have been forgotten. As a consequence, the 
American public’s patience with the difficulties and costs inherent in 
playing that global role have worn thin. Whereas previous unsuccessful 
and costly wars, in Korea in 1950 and Vietnam in the 1960s and 1970s, 
and previous economic downturns, such as with the energy crisis and 
crippling “stagflation” of the mid- to late 1970s, did not have the 
effect of turning Americans against global involvement, the unsuccessful
 wars in Iraq and Afghanistan and the financial crisis of 2008 have. 
Obama
 pursued an ambivalent approach to global involvement, but his core 
strategy was retrenchment. In his actions and his statements, he 
critiqued and repudiated previous American strategy and reinforced a 
national mood favoring a much less active role in the world and much 
narrower definition of American interests. The Obama administration 
responded to the George W. Bush administration’s failures in Iraq and 
Afghanistan not by restoring American power and influence but by further
 reducing them. Although the administration promised to “rebalance” 
American foreign policy to Asia and the Pacific, in practice that meant 
reducing global commitments and accommodating revisionist powers at the 
expense of allies’ security.
The
 administration’s early attempt to “reset” relations with Russia struck 
the first blow to America’s reputation as a reliable ally. Coming just 
after the Russian invasion of Georgia, it appeared to reward Moscow’s 
aggression. The reset also came at the expense of U.S. allies in Central
 Europe, as programs of military cooperation with Poland and the Czech 
Republic were jettisoned to appease the Kremlin. This attempt at 
accommodation, moreover, came just as Russian policy toward the West—not
 to mention Putin’s repressive policies toward his own people—was 
hardening. Far from eliciting better behavior by Russia, the reset 
emboldened Putin to push harder. Then, in 2014, the West’s inadequate 
response to the Russian invasion of Ukraine and seizure of Crimea, 
though better than the Bush administration’s anemic response to the 
invasion of Georgia (Europe and the United States at least imposed 
sanctions after the invasion of Ukraine), still indicated reluctance on 
the part of the U.S. administration to force Russia back in its declared
 sphere of interest. Obama, in fact, publicly acknowledged Russia’s 
privileged position in Ukraine even as the United States and Europe 
sought to protect that country’s sovereignty. In Syria, the 
administration practically invited Russian intervention through 
Washington’s passivity, and certainly did nothing to discourage it, thus
 reinforcing the growing impression of an America in retreat across the 
Middle East (an impression initially created by the unnecessary and 
unwise withdrawal of all U.S. troops from Iraq). Subsequent Russian 
actions that increased the refugee flow from Syria into Europe also 
brought no American response, despite the evident damage of those 
refugee flows to European democratic institutions. The signal sent by 
the Obama administration was that none of this was really America’s 
problem.
In
 East Asia, the Obama administration undermined its otherwise 
commendable efforts to assert America’s continuing interest and 
influence. The so-called “pivot” proved to be mostly rhetoric. 
Inadequate overall defense spending precluded the necessary increases in
 America’s regional military presence in a meaningful way, and the 
administration allowed a critical economic component, the Trans-Pacific 
Partnership, to die in Congress, chiefly a victim of its own party’s 
opposition. The pivot also suffered from the general perception of 
American retreat and retrenchment, encouraged both by presidential 
rhetoric and by administration policies, especially in the Middle East. 
The premature, unnecessary, and strategically costly withdrawal of 
American troops from Iraq, followed by the accommodating agreement with 
Iran on its nuclear program, and then by the failure to hold the line on
 threats to use force against Syria’s president, was noticed around the 
world. Despite the Obama administration’s insistence that American 
strategy should be geared toward Asia, U.S. allies have been left 
wondering how reliable the U.S. commitment might be when facing the 
challenge posed by China. The Obama administration erred in imagining 
that it could retrench globally while reassuring allies in Asia that the
 United States remained a reliable partner.
NATURE ABHORS A VACUUM
The
 effect on the two great revisionist powers, meanwhile, has been to 
encourage greater efforts at revision. In recent years, both powers have
 been more active in challenging the order, and one reason has been the 
growing perception that the United States is losing both the will and 
the capacity to sustain it. The psychological and political effect of 
the wars in Afghanistan and Iraq in the United States, which has been to
 weaken support for American global engagement across the board, has 
provided an opening.
It
 is a myth, prevalent among liberal democracies, that revisionist powers
 can be pacified by acquiescence to their demands. American 
retrenchment, by this logic, ought to reduce tensions and competition. 
Unfortunately, the opposite is more often the case. The more secure 
revisionist powers feel, the more ambitious they are in seeking to 
change the system to their advantage because the resistance to change 
appears to be lessening. Just look at both China and Russia: Never in 
the past two centuries have they enjoyed greater security from external 
attack than they do today. Yet both remain dissatisfied and have become 
increasingly aggressive in pressing what they perceive to be their 
growing advantage in a system where the United States no longer puts up 
as much resistance as it used to.
The
 two great powers have differed, so far, chiefly in their methods. China
 has until now been the more careful, cautious, and patient of the two, 
seeking influence primarily through its great economic clout and using 
its growing military power chiefly as a source of deterrence and 
regional intimidation. It has not resorted to the outright use of force 
yet, although its actions in the South China Sea are military in nature,
 with strategic objectives. And while Beijing has been wary of using 
military force until now, it would be a mistake to assume it will 
continue show such restraint in the future—possibly the near future. 
Revisionist great powers with growing military capabilities invariably 
make use of those capabilities when they believe the possible gains 
outweigh the risks and costs. If the Chinese perceive America’s 
commitment to its allies and its position in the region to be weakening,
 or its capacity to make good on those commitments to be declining, then
 they will be more inclined to attempt to use the power they are 
acquiring in order to achieve their objectives. As the trend lines draw 
closer, this is where the first crisis is likely to take place.
Russia
 has been far more aggressive. It has invaded two neighboring 
states—Georgia in 2008 and Ukraine in 2014—and in both cases hived off 
significant portions of those two nations’ sovereign territory. Given 
the intensity with which the United States and its allies would have 
responded to such actions during the four decades of the Cold War, their
 relative lack of a response must have sent quite a signal to the 
Kremlin—and to others around the world. Moscow then followed by sending 
substantial forces into Syria. It has used its dominance of European 
energy markets as a weapon. It has used cyberwarfare against neighboring
 states. It has engaged in extensive information warfare on a global 
scale.
More
 recently, the Russian government has deployed a weapon that the Chinese
 either lack or have so far chosen not to deploy—the ability to 
interfere directly in Western electoral processes, both to influence 
their outcomes and more generally to discredit the democratic system. 
Russia funds right-wing populist parties across Europe, including in France;
 uses its media outlets to support favored candidates and attack others;
 has disseminated “fake news” to influence voters, most recently in Italy’s referendum;
 and has hacked private communications in order to embarrass those it 
wishes to defeat. This past year, Russia for the first time employed 
this powerful weapon against the United States, heavily interfering in 
the American electoral process.
Although
 Russia, by any measure, is the weaker of the two great powers, it has 
so far had more success than China in accomplishing its objective of 
dividing and disrupting the West.
Although
 Russia, by any measure, is the weaker of the two great powers, it has 
so far had more success than China in accomplishing its objective of 
dividing and disrupting the West. Its interference in Western democratic
 political systems, its information warfare, and its role in creating 
increased refugee flows from Syria into Europe have all contributed to 
the sapping of Europeans’ confidence in their political systems and 
established political parties. Its military intervention in Syria, 
contrasted with American passivity, has exacerbated existing doubts 
about American staying power in the region. Beijing, until recently, has
 succeeded mostly in driving American allies closer to the United States
 out of concern for growing Chinese power—but that could change quickly,
 especially if the United States continues on its present trajectory. 
There are signs that regional powers are already recalculating: East 
Asian countries are contemplating regional trade agreements that need 
not include the United States or, in the case of the Philippines, are 
actively courting China, while a number of nations in Eastern and 
Central Europe are moving closer to Russia, both strategically and 
ideologically. We could soon face a situation where both great 
revisionist powers are acting aggressively, including by military means,
 posing extreme challenges to American and global security in two 
regions at once.
THE DISPENSABLE NATION
All
 this comes as Americans continue to signal their reluctance to uphold 
the world order they created after World War II. Donald Trump was not 
the only major political figure in this past election season to call for
 a much narrower definition of American interests and a lessening of the
 burdens of American global leadership. President Obama and Bernie 
Sanders both expressed a version of “America First.” The candidate who 
spoke often of America’s “indispensable” global role lost, and even 
Hillary Clinton felt compelled to jettison her earlier support for the 
Trans-Pacific Partnership. At the very least, there should be doubts 
about the American public’s willingness to continue supporting the 
international alliance structure, denying the revisionist powers their 
desired spheres of influence and regional hegemony, and upholding 
democratic and free market norms in the international system.
Coming
 as it does at a time of growing great-power competition, this narrowing
 definition of American interests will likely hasten a return to the 
instability and clashes of previous eras. The weakness at the core of 
the democratic world and the shedding by the United States of global 
responsibilities have already encouraged a more aggressive revisionism 
by the dissatisfied powers. That, in turn, has further sapped the 
democratic world’s confidence and willingness to resist. History 
suggests that this is a downward spiral from which it will be difficult 
to recover, absent a rather dramatic shift of course by the United 
States.
The
 weakness at the core of the democratic world and the shedding by the 
United States of global responsibilities have already encouraged a more 
aggressive revisionism by the dissatisfied powers.
That
 shift may come too late. It was in the 1920s, not the 1930s, that the 
democratic powers made the most important and ultimately fatal 
decisions. Americans’ disillusionment after World War I led them to 
reject playing a strategic role in preserving the peace in Europe and 
Asia, even though America was the only nation powerful enough to play 
that role. The withdrawal of the United States helped undermine the will
 of Britain and France and encouraged Germany in Europe and Japan in 
Asia to take increasingly aggressive actions to achieve regional 
dominance. Most Americans were convinced that nothing that happened in 
Europe or Asia could affect their security. It took World War II to 
convince them that was a mistake. The “return to normalcy”
 of the 1920 election seemed safe and innocent at the time, but the 
essentially selfish policies pursued by the world’s strongest power in 
the following decade helped set the stage for the calamities of the 
1930s. By the time the crises began to erupt, it was already too late to
 avoid paying the high price of global conflict.
In
 such times, it has always been tempting to believe that geopolitical 
competition can be solved through efforts at cooperation and 
accommodation. The idea, recently proposed by
 Niall Ferguson, that the world can be ruled jointly by the United 
States, Russia, and China is not a new one. Such condominiums have been 
proposed and attempted in every era when the dominant power or powers in
 the international system sought to fend off challenges from the 
dissatisfied revisionist powers. It has rarely worked. Revisionist great
 powers are not easy to satisfy short of complete capitulation. Their 
sphere of influence is never quite large enough to satisfy their pride 
or their expanding need for security. In fact, their very expansion 
creates insecurity, by frightening neighbors and leading them to band 
together against the rising power. The satiated power that
 Otto von Bismarck spoke of is rare. The German leaders who succeeded 
him were not satisfied even with being the strongest power in Europe. In
 their efforts to grow still stronger, they produced coalitions against 
them, making their fear of “encirclement” a self-fulfilling prophecy.

GIVE ‘EM AN INCH, THEY’LL TAKE A MILE
This
 is a common trait of rising powers—their actions produce the very 
insecurity they claim to want to redress. They harbor grievances against
 the existing order (both Germany and Japan considered themselves the 
“have-not” nations), but their grievances cannot be satisfied so long as
 the existing order remains in place. Marginal concession is not enough,
 but the powers upholding the existing order will not make more than 
marginal concessions unless they are compelled to by superior strength. 
Japan, the aggrieved “have-not” nation of the 1930s, did not satisfy 
itself by taking Manchuria in 1931. Germany, the aggrieved victim of 
Versailles, did not satisfy itself by bringing the Germans of the 
Sudetenland back into the fold. They demanded much more, and they could 
not persuade the democratic powers to give them what they wanted without
 resorting to war.
Granting
 the revisionist powers spheres of influence is not a recipe for peace 
and tranquility but rather an invitation to inevitable conflict.
Granting
 the revisionist powers spheres of influence is not a recipe for peace 
and tranquility but rather an invitation to inevitable 
conflict. Russia’s historical sphere of influence does not end in 
Ukraine. It begins in Ukraine. It extends to the Baltic States, to the 
Balkans, and to the heart of Central Europe. And within Russia’s 
traditional sphere of influence, other nations do not enjoy autonomy or 
even sovereignty. There was no independent Poland under the Russian 
Empire nor under the Soviet Union. For China to gain its desired sphere 
of influence in East Asia will mean that, when it chooses, it can close 
the region off to the United States—not only militarily but politically 
and economically, too.
China
 will, of course, inevitably exercise great sway in its own region, as 
will Russia. The United States cannot and should not prevent China from 
being an economic powerhouse. Nor should it wish for the collapse of 
Russia. The United States should even welcome competition of a certain 
kind. Great powers compete across multiple planes—economic, ideological,
 and political, as well as military. Competition in most spheres is 
necessary and even healthy. Within the liberal order, China can compete 
economically and successfully with the United States; Russia can thrive 
in the international economic order upheld by the democratic system, 
even if it is not itself democratic.
But
 military and strategic competition is different. The security situation
 undergirds everything else. It remains true today as it has since World
 War II that only the United States has the capacity and the unique 
geographical advantages to provide global security and relative 
stability. There is no stable balance of power in Europe or Asia without
 the United States. And while we can talk about “soft power” and “smart 
power,” they have been and always will be of limited value when 
confronting raw military power. Despite all of the loose talk of 
American decline, it is in the military realm where U.S. advantages 
remain clearest. Even in other great powers’ backyards, the United 
States retains the capacity, along with its powerful allies, to deter 
challenges to the security order. But without a U.S. willingness to 
maintain the balance in far-flung regions of the world, the system will 
buckle under the unrestrained military competition of regional powers. 
Part of that willingness entails defense spending commensurate with 
America’s continuing global role.
For
 the United States to accept a return to spheres of influence would not 
calm the international waters. It would merely return the world to the 
condition it was in at the end of the 19th century, with competing great
 powers clashing over inevitably intersecting and overlapping spheres. 
These unsettled, disordered conditions produced the fertile ground for 
the two destructive world wars of the first half of the 20th century. 
The collapse of the British-dominated world order on the oceans, the 
disruption of the uneasy balance of power on the European continent as a
 powerful unified Germany took shape, and the rise of Japanese power in 
East Asia all contributed to a highly competitive international 
environment in which dissatisfied great powers took the opportunity to 
pursue their ambitions in the absence of any power or group of powers to
 unite in checking them. The result was an unprecedented global calamity
 and death on an epic scale. It has been the great accomplishment of the
 U.S.-led world order in the 70 years since the end of World War II that
 this kind of competition has been held in check and great power 
conflicts have been avoided. It will be more than a shame if Americans 
were to destroy what they created—and not because it was no longer 
possible to sustain but simply because they chose to stop trying.
