America’s Allies
Donald Trump’s rise
was supposed to have upended the liberal international order. In his first
term, Trump openly disparaged longtime European
allies, pulled out of international treaties such as the Paris climate
agreement, and decried how the United States was subsidizing its allies through
military support and trade deficits. Yet Trump’s aggressive unilateralism did
not break U.S. alliances. Shaken and often irritated by Washington’s bullying,
the allies nevertheless did not drift away from the world’s preeminent
superpower. The foreign relations doctrines, defense spending, and geopolitical
alignments of core U.S. partners such as France, Germany, Japan, and South
Korea did not shift in any meaningful way during the first Trump
administration. Instead, these countries accommodated Trump because they felt
that loosening ties with the United States would be more dangerous to their
economic and security interests than trying to stand up to his abuse.
Trump’s second term has put this dynamic to an
even sterner test. The president’s disdain for U.S. allies and partners is much
greater this time around. He has talked about annexing
Canada and Greenland, bombing Mexico, retaking the Panama Canal, and giving
up on Ukraine and Taiwan, to name just a few. Trump, claiming that allies are
ripping off the United States, is demanding large, ill-defined investments in
the United States that look a lot like bribes. For instance, he wants a
staggering $600 billion investment guarantee from the European Union to be used
at his discretion. He seems to be leaning into the notion that alliances are
not pillars of a mutually beneficial network but elements of a protection
racket—and that it’s high time for the United States to reap the rewards.
If allies had hoped
that the election of Joe Biden in 2020 would
restore traditional American liberal internationalism, Trump’s reelection
proves that the foreign policy belligerence and explicit quid pro quo basis for
U.S. commitments evident in his first term were not an aberration. Instead, as
demonstrated in the administration’s just-released National Security Strategy,
it will probably be a core part of U.S. foreign policy moving forward. Future
Republican leaders are likely to continue to promote Trump’s overall policy
direction. And even if the Democrats retake control, the ability of
Trump-aligned Republicans to exercise power in a two-party system will
undermine the United States’ reliability as an ally.
So far in Trump’s
second term, U.S. allies have not yet defected. In October, Trump visited Japan
and South Korea, and each country’s leaders signaled their desire to stay in
the president’s good graces. Just as we concluded in 2022, the allies still seem
to be all right. But they are much more worried than before. Unlike eight years
ago, countries can no longer wish away the implications of a United States that
might not support them in a crisis. Instead, over the next decade, it is likely
that U.S. allies will start to noticeably drift away. They may still hope for
U.S. support, but they are also starting to hedge against the possibility that
the United States will be absent when problems arise by building alternative
alliance structures, considering obtaining nuclear weapons, and even brokering
separate peace deals with, rather than confronting, regional opponents. Without
being able to predict how Trump would respond to calls for help in a major war
or a nuclear crisis with China, Russia, or North Korea, U.S. allies have no
choice but to shift their long-term strategies to reduce their dependence on
Washington.

Anxiously Attached
In the first year of
Trump’s second term, U.S. allies have remained tied to the United States. As in
Trump’s first term, many allied leaders seem to believe that Trump can be
wrangled into commitments and binding deals that will keep the United States involved
in supporting their security needs. European efforts to engage Washington on Ukraine’s behalf in its war with Russia show how
dependent on the United States the allies still are. Trump does not appear to
want to help Ukraine, and he has expressed his admiration for Russian President
Vladimir Putin. Yet many European countries are not swiftly ramping up their
defense industrial spending to a level that could meet Ukraine’s war needs
independently of U.S. financial and weapons support. Nor are they finding
homegrown alternatives to U.S. logistics and intelligence gathering. Three and
a half years into the conflict, European leaders are still coming to the White
House to flatter Trump rather than making themselves less reliant on the United
States.
U.S. allies in East
Asia, too, have sought to get closer to Trump rather than push him away. Both
Japan and South Korea have capitulated to Trump’s investment demands. As part
of the trade deal it struck with Washington in July, for instance, Tokyo agreed
to invest $500 billion in the United States, although whether Japan actually
hits this target and the exact details of who controls this money remain
contested. And despite their proximity to China, North Korea, and Russia,
neither Japan nor South Korea has ramped up defense spending enough to free
itself from reliance on the United States. U.S. military forces stationed in
Japan and South Korea remain deeply interwoven with their host militaries, and
joint drills continue. In fact, the United States is pushing both countries to
allow U.S. military assets based on their territory to be used in offensive
operations to counter China, not simply for the protection of the host
countries. Knowing that they do not want to face surrounding threats alone,
U.S. allies in East Asia continue to accommodate Trump’s demands even as his
rhetoric grows tougher and his actions more aggressive.

To Hedge or Not to Hedge
Hedging will be
difficult and costly. The most obvious reason that U.S. allies continue to
appease Trump is the deep entanglement of their militaries with that of the
United States. It will take a long time and a huge amount of resources to
unwind that interoperability. U.S. allies currently access many logistics and
intelligence-gathering systems, such as satellites, at low cost from the United
States, which they would otherwise have to pay for themselves. And the publics
around the world have long accustomed themselves to the U.S. security blanket.
Pursuing greater independence would mean higher taxes, social spending cuts,
and possibly conscription or nuclearization—all of which are likely to be
jarring and unnerving to citizens, who may vote out of office those politicians
who seek the path of hedging.
But having its allies
seeking alternatives is not all bad news for Washington. If U.S. allies become
more autonomous in paying for their own security, the United States, which has
long complained about free riding, will achieve what it has long wanted: allies
that are more able to support themselves. And as its allies gain more autonomy,
there is the possibility that policymakers in Washington, including those with
an “America first” mindset, will recognize how a robust alliance network
benefits the United States by giving it access points to conduct military and
intelligence operations around the world without needing to foot the entire
bill.
In an ideal world,
the United States would still be the best security provider for U.S. allies.
For the leaders of many of these countries, it is worth hoping that, as Winston
Churchill supposedly quipped, the United States will always do the right thing
after exhausting all other options. But these allies do not find themselves in
an ideal world, and the possibility that the United States under Trump or one
of his followers will ultimately do the right thing by its allies is more in
doubt than perhaps at any time in the nearly 80 years since the modern U.S.
alliance system took shape. Hoping that the United States eventually does the
right thing or rediscovers the benefits of strong alliances is not a viable
long-term strategy. The prudent step is hedging. America’s allies remain
committed to Washington for now, but they are anxious enough to start looking
elsewhere for support.
