Since the outbreak of the war in Ukraine, former President Donald Trump has pursued a diplomatic approach reminiscent of the 1945 Yalta Conference, where Allied leaders shaped the post-World War II order. However, his efforts have drawn criticism for sidelining Ukraine and its European partners in favor of negotiations focused primarily on Russia’s position.
At the historic Yalta meeting, Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin agreed on dividing Europe into zones of influence, a pragmatic but contentious arrangement that shaped international relations for decades. Trump’s vision, which emerged during his second term, appeared to seek a similar grand bargain among great powers, with Ukraine treated as a secondary actor obliged to accept outcomes determined by Russia and the United States.
Though Trump’s policy toward Ukraine has fluctuated, his attempts to define the war’s resolution have focused on accommodating Russian President Vladimir Putin’s status as a great-power leader. This approach diverges sharply from support for Ukraine’s sovereignty. Kyiv has publicly accused the White House under Trump’s influence of restricting Ukraine’s access to critical military resources, such as Starlink satellite internet, and delaying shipments of Patriot interceptor missiles—claims U.S. officials have denied.
In parallel, Trump has taken steps to improve economic ties with Russia, including agreements to purchase Russian diesel fuel and exemptions for Moscow from new sanctions. Reports have surfaced about potential trilateral talks involving the United States, Russia, and China at an upcoming international summit, evoking a modernized version of the Yalta-style conference, albeit with China replacing Britain as a key participant.
Analysts caution that such a framework risks irrelevance given the current military and political dynamics. Unlike the Soviet Union in 1945, Russia is not in a dominant position following its setbacks in Ukraine. Putin appears intent on leveraging diplomatic negotiations to gain concessions without a definitive military victory—a strategy that the United States lacks the unilateral authority to endorse or enforce.
Experts note that the United States no longer holds the robust influence it commanded in postwar Europe. Then, American military power, nuclear capability, and moral standing supported a leadership role that Trump’s tenure has arguably eroded. His imposition of tariffs on European allies, threats concerning Greenland’s status, and plans to reduce U.S. military deployments have raised doubts about Washington’s commitment to European security.
Trump’s reduction of aid to Ukraine and diminished financial support for its war effort have compounded these concerns. His perceived weakening of NATO’s collective defense obligations, particularly the Article 5 commitment, has disrupted transatlantic unity and complicated Ukraine’s defense strategies. Meanwhile, European nations, led by Germany, have begun increasing defense expenditures and expanding their own military capabilities, reducing reliance on U.S. assistance.
This evolving landscape reflects a gradual but significant shift in global power relations. Europe’s growing defense-industrial capacity and broad network of allies, including Ukraine, signal a diminished role for the United States under Trump’s approach and suggest a multipolar negotiation environment far more complex than the historical precedent Trump appears to emulate.
