"In March, as President Biden was
facing pressure to intensify U.S. involvement in Ukraine, he responded by
invoking the specter of World War III four times in one
day.
“Direct conflict between NATO and
Russia is World War III,” he said, “something
we must strive to prevent.” He underscored the point
hours later: “The idea that we’re going to send in offensive equipment and have
planes and tanks and trains going in with American pilots and American crews —
just understand, and don’t kid yourself, no matter what you all say, that’s
called World War III, OK?”
More than any other presidential
statement since Sept. 11, 2001, Mr. Biden’s warning signaled the start of a new
era in American foreign policy.
Throughout my adult life and that of most Americans today,
the United States bestrode the world, essentially unchallenged and unchecked.
A few years ago, it was still
possible to expect a benign geopolitical future. Although “great power competition”
became the watchword of Pentagonese, the phrase could as easily imply sporting
rivalry as explosive conflict. Washington, Moscow and Beijing would stiffly
compete but could surely coexist.
How quaint. The United States now
faces the real and regular prospect of fighting adversaries strong enough to do
Americans immense harm. The post-Sept. 11 forever wars have been costly, but a
true great power war — the kind that used to afflict Europe — would be
something else, pitting the United States against Russia or even China, whose
economic strength rivals America’s and whose military could soon as well.
This grim reality has arrived with
startling rapidity. Since February, the military operation in Ukraine has
created an acute risk of U.S.-Russia conflict. It has also vaulted a Chinese
invasion of Taiwan to the forefront of American fears and increased
Washington’s willingness to respond with military force. “That’s called World
War III,” indeed.
Yet how many Americans can truly
envision what a third world war would mean? Just as great power conflict looms
again, those who witnessed the last one are disappearing. Around 1 percent of U.S.
veterans of World War II remain alive to tell their stories. It is
estimated that by the end of this decade, fewer than 10,000 will be left. The
vast majority of Americans today are unused to enduring hardship for foreign
policy choices, let alone the loss of life and wealth that direct conflict with
China or Russia would bring.
Preparing the country shouldn’t
begin with tanks, planes and ships. It will require a national effort of historical
recovery and imagination — first and foremost to enable the American people to
consider whether they wish to enter a major war if the moment of decision
arrives.
Navigating
great power conflict is hardly a novel challenge for the United States. By
1945, Americans had lived through two world wars. The country emerged
triumphant yet sobered by its wounds. Even as the wars propelled the United
States to world leadership, American leaders and citizens feared that a third
world war might be as probable as it today appears unthinkable. Perhaps that is
one reason a catastrophe was avoided.
For four decades, America’s postwar presidents appreciated
that the next hot war would likely be worse than the last. In the nuclear age,
“we will be a battlefront,”
Truman said. “We can look forward to destruction here, just as the other
countries in the Second World War.” This insight didn’t keep him or his
successors from meddling in Third World countries,
from Guatemala to Indonesia, where the Cold War was brutal. But U.S. leaders,
regardless of party, recognized that if the United States and the Soviet Union
squared off directly, nuclear weapons would lay waste to the
American mainland.
Nuclear terror became part of
American life, thanks to a purposeful effort by the government to prepare the
country for the worst. The Federal Civil Defense
Administration advised citizens to build bomb shelters in their
backyards and keep clean homes so there would be less clutter to ignite in a
nuclear blast. The film “Duck and Cover,”
released in 1951, encouraged schoolchildren to act like animated turtles and
hide under a makeshift shell — “a table or desk or anything else close by” — if
nukes hit. By the 1960s, yellow-and-black signs
for fallout shelters dotted American cities.
The specter of full-scale war kept the Cold War superpowers
in check. In 1950, Truman sent U.S. troops to defend South Korea against
invasion by the Communist North, but his resolve had limits. After Gen. Douglas
MacArthur implored Truman to blast China and North Korea
with 34 nuclear bombs, the president fired the general. Evoking the
“disaster of World War II,” he told the nation:
“We will not take any action which might place upon us the responsibility of
initiating a general war — a third world war.”
The extreme violence of the world
wars and the anticipation of a sequel also shaped President John F. Kennedy’s
decisions during the Cuban missile crisis, when the Soviet Union moved to place
nuclear weapons 90 miles from Florida. Kennedy, who had served in the Pacific
and rescued a fellow sailor after their ship went down, grew frustrated with
his military advisers for recommending preventative strikes on Soviet missile
sites. Instead of opening fire, he imposed a naval blockade around Cuba and
demanded that the Soviets withdraw their missiles. A one-week superpower
standoff ensued. Approximately 10 million Americans
fled their homes. Crowds descended on civil defense offices to find out how to
survive a nuclear blast.
The Soviets backed down after Kennedy secretly promised to
remove U.S. Jupiter missiles from Turkey.
The world had come so close to
nuclear Armageddon that Kennedy, citing the danger of a third
and total war, took the first steps toward détente before his death
in 1963.
But
memory is never static. After the Soviet Union collapsed and generations turned
over, World War II was recast as a moral triumph and no longer a
cautionary tale.
In the 1990s, an outpouring of film,
history and literature celebrated the “greatest generation,” as journalist Tom
Brokaw anointed those who won the war for America. Under their watch, the
United States had saved the world and stopped the Holocaust — which
retrospectively vaulted to the center of the war’s
purpose, even though stopping the mass murder of European Jews was not why the
United States had entered. A new generation, personally untouched by great
power war, reshaped the past, revering their elders but simplifying the often varied
and painful experiences of veterans.
In this context, the double lesson
of the world wars — calling America to lead the world but cautioning it not to
overreach — narrowed to a single-minded exhortation to sustain and even expand
American power. Presidents began to invoke World War II to glorify the struggle
and justify American global dominance. On the anniversary of Pearl Harbor in
1991, George H.W. Bush told the country
that “isolationism flew escort for the very bombers that attacked our men 50
years ago.” Commemorating the 50th anniversary of D-Day in 1994, Bill Clinton
recalled how the Allied troops gathered “like the stars of a majestic
galaxy” and “unleashed their democratic
fury,” fighting a battle that continued.
In 2004 the imposing World War II
Memorial, one decade and $197 million in the making, went up between the
Washington Monument and the Lincoln Memorial. George W. Bush, a year into
invading Iraq, gave the dedication:
“The scenes of the concentration camps, the heaps of bodies and ghostly
survivors, confirmed forever America’s calling to oppose the ideologies of
death.” Preventing a repeat of World War II no longer involved exercising
caution; it meant toppling tyrants.
Besides, why dwell on the horrors of
global conflict at a time when no such thing even seemed possible? With
post-Soviet Russia reeling and China poor, there were no more great powers for
the United States to fight. Scholars discussed the obsolescence of major war.
It wasn’t just major war that seemed passé. So did the need
to pay any significant costs for foreign policy choices. Since the Vietnam War
roiled American society, leaders moved to insulate the American public from the
harms of any conflict, large or small: The creation of an all-volunteer force
did away with the draft; air power bombed targets from safe heights; the advent
of drones allowed killing by remote control.
The deaths of more than 7,000 service members in
the post-Sept. 11 wars — and approximately four times as many by suicide —
devastated families and communities but were not enough to produce a
Vietnam-style backlash. Likewise, although the wars have cost a whopping $8 trillion and
counting, the payments have been spread over decades and passed to the future.
Not having to worry about the
effects of wars — unless you enlist to fight in them — has nearly become a
birthright of being American.
That
birthright has come to an end. The United States is entering an era of intense
great power rivalry that could escalate to large-scale conventional or nuclear
war. It’s time to think through the consequences.
The “acute threat,” as the new National Security
Strategy states, comes from Moscow. President Vladimir Putin
controls thousands of nuclear weapons, enough to destroy civilization many
times over.
Since the military operation in
Ukraine, he has threatened to use them.
Mr. Putin could plausibly act on that threat
under several scenarios: if U.S. or NATO forces directly enter the conflict, if
he believes his rule is threatened or if Ukrainian forces verge on retaking
Crimea. No one knows precisely what might prompt the Kremlin to employ a
nuclear weapon, but Mr. Biden recently said that the risk of Armageddon was the
highest it has been since the Cuban missile crisis.
Mr. Biden has ruled out using force
to defend Ukraine. His administration is pursuing a finely tailored objective:
It seeks to strengthen Ukraine’s position on the battlefield in order to
strengthen its hand in peace negotiations. That goal does not commit the United
States to ensuring a complete Ukrainian victory. Yet the Ukrainian Army’s
recent successes have prompted American commentators to redouble their backing
for Kyiv and further marginalize talk of diplomacy (not that Mr. Putin has
shown any readiness to stop).
If the possibility of war with Russia was not enough, U.S.
relations with China are in free fall, setting up the world’s two leading
powers to square off for decades to come.
Despite Mr. Biden’s caution toward Russia, he is
contributing to the rising chances of conflict with China. In a series of interviews,
he asserted that the United States has a commitment to defend Taiwan (in fact,
it is obligated only to help arm the island) and vowed to send U.S. troops in
the event of a Chinese invasion. These repeated gaffes are likely intended to
deter Beijing in light of its many recent military
maneuvers around the island. But especially in tandem with
high-level congressional visits to Taipei, they risk implying that
the United States wishes to keep Taiwan permanently separated from the mainland
— a position it is hard to imagine Beijing will ever accept.
Equally important, Mr. Biden seems
to be saying that defending Taiwan would be worth the price of war with China.
But what would such a war entail?
A series of recent war games held by think tanks help us to
imagine what it would look like: First, a war will likely last a long time and take many
lives. Early on, China would have incentives to mount a massive attack with its
now highly developed long-range strike capability to disable U.S. forces
stationed in the Pacific. Air Force Gen. Mark D. Kelly said that China’s forces
are “designed to inflict more casualties in
the first 30 hours of combat than we’ve endured over the last 30
years in the Middle East.”
In most rounds of a war game recently conducted by the
Center for Strategic and International Studies, the United States swiftly lost
two aircraft carriers, each carrying at least 5,000 people, on top of hundreds
of aircraft, according to reports.
One participant noted that although each simulation varied, “what almost never
changes is it’s a bloody mess and both sides take some terrible losses.” At
some stage, those Selective Service registrations required of young American
men might need to be expanded and converted into a draft.
Second, each side would be tempted
to escalate. This summer, the Center for a New American Security held a war
game that ended with China detonating a nuclear weapon near Hawaii. “Before
they knew it,” both Washington and Beijing “had crossed key red lines,
but neither was willing to back down,” the conveners concluded. Especially in a
prolonged war, China could mount cyberattacks to disrupt
critical American infrastructure. It might shut off the power in a
major city, obstruct emergency services or bring down communications systems. A
new current of fear and suspicion would course through American society,
joining up with the nativism that has reverberated through national politics
since Sept. 11.
The economic consequences would be
equally severe. A Chinese invasion of Taiwan, which produces most of the
world’s advanced semiconductors, would profoundly damage the U.S. and global
economy regardless of Washington’s response. (To this end, the United States
has been trying to move more semiconductor
manufacturing home.) But a U.S.-China war would risk catastrophic
losses. Researchers at RAND estimate that a yearlong conflict would slash America’s gross
domestic product by 5 to 10 percent. By contrast, the U.S. economy
contracted 2.6 percent in 2009, the worst year of the Great Recession. The
gas-price surge early in the Ukraine war provides only the slightest preview of
what a US.-China war would generate. For the roughly three-fifths of Americans
who currently live paycheck to paycheck, the war would come home in millions of
lost jobs, wrecked retirements, high prices and shortages.
In short, a war with Russia or China would likely injure the
United States on a scale without precedent in the living memory of most
citizens. That, in turn, introduces profound uncertainty about how the American
political system would perform. Getting in would be the easy part. More elusive
is whether the public and its representatives would maintain the will to fight
over far-flung territories in the face of sustained physical attack and
economic calamity. When millions are thrown out of work, will they find
Taiwan’s cause worth their sacrifice? Could national leaders compellingly
explain why the United States was paying the grievous price of World War III?
These questions will be asked during
a conflict, so they ought to be asked in advance. Even those who think the
United States should fight for Ukraine or Taiwan have an interest in educating
the public about the stakes of great power conflict in the nuclear and cyber
age.
The last nuclear-related sign I saw,
a few weeks ago, proudly declared a small liberal suburb of Washington, D.C.,
to be a “nuclear-free zone.” “Duck and Cover” deserves a 21st-century remake —
something a bit more memorable than the Department of Homeland Security’s “Nuclear Explosion” fact sheet, which nonetheless
contains sound advice.
(For example, after the shock wave passes, you have 10
minutes or more to find shelter before the radioactive fallout arrives.)
For every moral condemnation of
adversaries’ actions, Americans should hear candid assessments of the costs of
trying to stop them. A war game broadcast on “Meet the Press”
in May offered one model. Even better to follow it with a peace game, showing
how to avoid devastation in the first place.
Without raising public awareness, political leaders risk
bringing about the worst-case outcome — of waging World War III and losing it
when the country recoils.
As international relations have
deteriorated in recent years, critics of U.S. global primacy have frequently warned
that a new cold war was
brewing. I have been among them. Yet
pointing to a cold war in some ways understates the danger. Relations with
Russia and China are not assured to stay cold. During the original Cold War,
American leaders and citizens knew that survival was not inevitable. World-rending
violence remained an all-too-possible destination of the superpower contest,
right up to its astonishing end in 1989.
Today the United States is again assuming the primary burden
of countering the ambitions of governments in Moscow and Beijing. When it did
so the first time, it lived in the shadow of world war and acted out of a frank
and healthy fear of another. This time, lessons will have to be learned without
that experience.
