President Donald Trump's abrupt decision to withdraw thousands of U.S. troops from Germany has thrust European nations into an urgent debate over their collective security obligations, with leaders acknowledging Monday that the continent must shoulder greater responsibility for its own defense even as questions mount about NATO coordination and regional stability.
The Pentagon announced last week it would pull some 5,000 troops out of Germany, and Trump told reporters on Saturday the U.S. plans on "cutting a lot further." Trump offered no reason for the move, which blindsided NATO. His decision came amid an escalating dispute with German Chancellor Friedrich Merz, who said the U.S. has been humiliated by Iran in talks to end the war it launched with Israel on Feb. 28. Trump has also expressed anger over European allies' reluctance to get involved in the conflict.
European Leaders Confront Security Gap
European leaders meeting at a summit in Yerevan, Armenia, sought to downplay the impact of 5,000 fewer troops in Germany while acknowledging that it provides a useful nudge for the continent to step up its role within NATO. Norwegian Prime Minister Jonas Gahr Støre said, "I do not see those figures as dramatic, but I think they should be handled in a harmonious way inside the framework of NATO." British Prime Minister Keir Starmer said "there needs to be a stronger European element in NATO, I have no doubt about that."
The European Union's foreign policy chief, Kaja Kallas, said the timing of Trump's announcement came as a surprise, even though there has been "talk about withdrawal of U.S. troops for a long time from Europe." Asked whether she believes Trump is trying to punish Merz, Kallas said: "I don't see into the head of President Trump, so he has to explain it himself." Merz did not attend the European Political Community summit in Yerevan, which included about 30 European leaders, plus Canadian Prime Minister Mark Carney.
Germany Still Awaiting Details
At a military exercise in northern Germany, the country's defense minister, Boris Pistorius, said Berlin has not yet received "official confirmation of when and how this is supposed to happen, on what scale." He said the reduction of U.S. troops "would not put into question NATO's deterrence capability." European countries and Canada have increased defense spending and military recruitment efforts over the last year in response to Trump's threats.
NATO Secretary-General Mark Rutte also played down the significance of fewer U.S. troops in Germany, while acknowledging U.S. "disappointment" about the level of European support for the Iran war. France and the U.K. have given U.S. forces limited use of bases on their territories to attack Iran. Spain has outright denied U.S. forces the use of its airspace and bases. Rutte said, "I would say the Europeans have heard a message."
Coordination Concerns Mount
European allies and Canada have known since early last year that Trump would pull some troops out of Europe, and some were pulled out of Romania about 7 months ago, but U.S. officials had pledged to coordinate any moves with NATO allies to avoid creating a security vacuum. NATO spokesperson Allison Hart said over the weekend that officials at the 32-nation military alliance "are working with the U.S. to understand the details of their decision on force posture in Germany."
With the ceasefire between the U.S. and Iran looking shakier, Rutte said European nations "have decided to pre-position assets, key assets, close to the theater for the next phase." He provided no further details. European leaders have insisted their countries would not help police the Strait of Hormuz, a key energy trade route, until the war is over. French President Emmanuel Macron said, "If the United States is ready to reopen Hormuz, that's great. That's what we've been asking for since the beginning," but he underlined that Europeans are not ready to get involved in any operation "that does not seem clear."
Why This Matters:
The unilateral withdrawal of U.S. troops from Germany without full NATO coordination raises fundamental questions about collective security frameworks that have underpinned European stability for decades. While European nations have increased defense spending in response to previous threats, the abrupt nature of this decision highlights the vulnerability of relying on unpredictable unilateral actions rather than coordinated multilateral planning. The move comes as Europe faces multiple security challenges, and the lack of clarity about when and how the withdrawal will proceed complicates defense planning for nations already grappling with increased military obligations. For workers and communities in Germany hosting these bases, the decision carries economic implications beyond security concerns. The episode underscores the urgent need for stronger European defense cooperation and investment in collective security institutions that can provide stability independent of shifting political winds across the Atlantic.
