Trump’s troop cuts in Germany raise doubts over US commitment to NATO and European security cooperation.
European officials say efforts to keep the United States firmly anchored in the North Atlantic Treaty Organization are facing fresh uncertainty after Donald Trump ordered a reduction of American troops in Germany.
The decision to withdraw about 5,000 US troops, announced on Friday, has underscored growing tensions between Washington and its European allies, particularly over the ongoing Iran war and burden-sharing within the alliance.
While NATO officials were not surprised by the substance of the move given longstanding calls for Europe to take greater responsibility for its own defence the manner in which it was executed has raised alarm. European leaders say there was little prior consultation and US officials linked the decision to criticism from German Chancellor Friedrich Merz over Washington’s handling of the conflict.
German lawmaker Siemtje Moeller warned that the move sends a troubling political signal about the reliability of long-standing alliances, suggesting that established partnerships may now be subject to abrupt policy shifts.
Further concern has come from the cancellation of plans to deploy long-range US Tomahawk missiles to Germany, an agreement reached under former President Joe Biden. The reversal highlights shifting US priorities as military resources are redirected toward the Iran conflict.
Strains have been exacerbated by Trump’s accusations that European allies are not doing enough to support the United States in the war, alongside suggestions that Washington could reconsider its commitment to NATO’s collective defence clause.
The alliance has also faced additional strain following Trump’s controversial remarks about taking Greenland from Denmark, a fellow NATO member. Although NATO Secretary General Mark Rutte helped ease immediate tensions, diplomats say underlying disputes remain unresolved.
European officials now fear further disruptions ahead of a summit of NATO’s 32 leaders scheduled to take place in Ankara in July, particularly if the Iran conflict continues.
Despite frustrations, defence experts say Europe has little choice but to maintain close ties with Washington due to its reliance on US military capabilities as a deterrent against Russia.
In a bid to reassure the United States, several European countries including Britain, France, Germany and Italy have continued to provide logistical and operational support during the Iran campaign, even as public opposition to the war remains high across the continent.
At the same time, European leaders are making a broader case for the strategic importance of NATO, emphasising their contributions to potential post-war missions, including securing the Strait of Hormuz.
However, divisions within Europe have become more pronounced. Western European nations such as France, Germany and Spain have openly criticised the war, while eastern members concerned about Russia have taken a more cautious stance.
Rutte has also cautioned against anti-war rhetoric, arguing that it risks undermining alliance unity at a critical moment.
As NATO navigates one of its most challenging periods in recent years, diplomats say the immediate priority is maintaining cohesion through the upcoming summit, even as uncertainty over US commitment continues to loom.
