President Donald Trump has announced that the United States will reduce its military presence in Germany by far more than the 5,000 troops the Pentagon ordered home on Friday, signalling a deliberate escalation in his confrontation with European allies over the war in Iran. Speaking to reporters in Florida, Trump said the cuts would go “a lot further than 5,000,” a figure that already represented roughly 15 per cent of the 36,000 American soldiers stationed in the country. The decision, framed by senior defence officials as punitive, follows a heated exchange with German Chancellor Friedrich Merz, who had accused Washington of being “humiliated” by Tehran and lacking an exit strategy.

Viewed from Berlin, the move was hardly a surprise. Defence Minister Boris Pistorius described the withdrawal as “foreseeable” and reiterated that Europe must shoulder more responsibility for its own security. Germany, he noted, was already expanding the Bundeswehr and accelerating procurement.

Yet his insistence that the American presence remained in the mutual interest of both sides underscored the unease beneath the calm official response. Across the Atlantic, the withdrawal drew rare bipartisan criticism. Republican chairs of the armed services committees in Congress warned that reducing forces in Germany risked sending “the wrong signal” to Vladimir Putin and undermining deterrence on NATO’s eastern flank.

Polish Prime Minister Donald Tusk went further, declaring that the greatest threat to the transatlantic community was “the ongoing disintegration of our alliance.” NATO itself, through spokesperson Allison Hart, said it was working with Washington to understand the details and stressed the need for Europe to invest more in collective defence. The alliance, she added, remained confident in its ability to deter, but the remark carried an implicit plea for a halt to what many European capitals see as a deliberate unravelling. The Pentagon’s order cancels a Biden-era plan to station a long-range artillery battalion in Germany and will reduce America’s European footprint to levels last seen before Russia’s full-scale invasion of Ukraine in 2022.

Beyond Germany, Trump has threatened similar reductions in Italy and Spain, which have also resisted the White House’s military campaign against Iran. Analysts in London and Paris note that while the immediate trigger is a personal feud with Merz, the underlying logic reflects a sustained American push to shift the burden of European defence onto European shoulders — a demand that has become explicit in Trump’s second term. For Germany and its neighbours, the withdrawal is both a warning and a catalyst.

The challenge now is whether Europe can accelerate its own military integration fast enough to compensate for a partner that is increasingly willing to use its troops as leverage in transatlantic disputes.
