Iran War Accelerates NATO Fracture as European Allies Question US Alliance Leadership

The Pentagon this week announced the withdrawal of 5,000 U.S. troops from Germany, roughly 14 percent of the American presence there, on orders from Defense Secretary Hegseth, NPR reported. The announcement followed German Chancellor Merz's public statement that Washington lacked a clear exit strategy in Iran and that Tehran had "humiliated" the U.S. in peace talks. Spain refused U.S. access to two joint military bases in southern Spain for Iran operations, and UK Prime Minister Starmer declared publicly "This is not our war," drawing open criticism from Trump, also per NPR. Canadian Prime Minister Carney attended a European Political Community summit in Armenia as the first non-European leader invited to such a session and told the gathering that the international order could be "rebuilt out of Europe."

Analysis
Spain's formal base denial and the Pentagon's actual Germany drawdown, not floated but ordered, mark a shift from coercive rhetoric to operational rupture. The United States is very unlikely to cease functioning as NATO's de facto leading power by end of 2028. European defense budgets remain well below autonomous deterrence requirements, no command architecture exists to absorb US C2 functions, and Canada's EPC invitation carries no treaty weight; these are structural claims with limited independent corroboration, given Eurasia Review's opinion-only contribution. The public defiance may instead be primarily domestic calibration, leaders absorbing Washington's anger while preserving core guarantees rather than pursuing durable realignment.
