Trump’s Troop Cut Threat Shakes NATO as Alliance Faces Growing Rift Over Europe’s Defense

President Donald Trump has reignited concerns about the future of the transatlantic alliance after reportedly considering a dramatic reduction of U.S. troops stationed in Europe, a move that would signal mounting frustration with NATO allies and deepen uncertainty over Washington’s long-term security commitments.

According to sources familiar with internal White House discussions, Trump suggested cutting the American military presence in Europe by as much as one-third during a meeting this spring, questioning whether such a move would send a clear message to allies he believes have failed to support U.S. military objectives.

The proposal reportedly emerged after several NATO members declined to participate in the U.S.-led military operation against Iran, a decision that fueled Trump’s longstanding criticism that European allies rely heavily on American military power while contributing too little to collective defense.

Although the administration ultimately stopped short of announcing an immediate troop reduction, the Pentagon reportedly canceled planned military deployments to Europe and withdrew additional personnel from the region. Defense Secretary Pete Hegseth had been expected to unveil deeper force reductions during a NATO meeting in June before the proposal was replaced with a comprehensive six-month review of U.S. troop deployments across Europe.

Speaking after the meeting, Hegseth warned that the review would evaluate the performance of individual allies, suggesting that future American military commitments would depend on whether member states met Washington’s expectations on defense spending and strategic cooperation.

The issue is expected to dominate discussions as Trump travels to Turkey for a high-stakes NATO summit, where alliance leaders will seek to reassure one another amid growing geopolitical tensions and Russia’s continued security challenge to Europe.

Trump has repeatedly argued that European nations must assume greater responsibility for their own defense, maintaining that the United States has carried a disproportionate share of NATO’s military burden for decades. His latest remarks have revived fears among European officials that Washington could scale back its military footprint at a time when unity remains essential to the alliance’s deterrence strategy.

While no final decision has been announced, analysts say even the suggestion of a major troop reduction underscores a shifting U.S. approach toward NATO. As alliance leaders gather to chart their collective security strategy, Trump’s warning has placed renewed pressure on European governments to demonstrate stronger commitments to defense spending and burden-sharing, while raising fresh questions about the future cohesion of the world’s most powerful military alliance.
