Hegseth Announces Six-Month Review of US Forces in Europe and Blasts NATO Allies Over Iran War Support

BLUFWhether the six-month review yields net withdrawal or eastward redistribution toward Poland remains genuinely uncertain, but the performance-linked framing permanently ends Europe's assumption of unconditional American presence.

Defense Secretary Hegseth announced a six-month Pentagon review of U.S. force posture in Europe at a NATO defense ministers meeting in Brussels on Thursday, with troop deployments and base locations made contingent on how quickly European allies take primary responsibility for their own defense 123. Hegseth called it "shameful" that European allies denied U.S. forces base access and overflight rights during the Iran war, saying those denials "put America's sons and daughters at risk" 1234. Stars and Stripes reported Spain has drawn particular criticism for refusing base access during the campaign; Hegseth also announced that annual U.S. NATO dues contributions would be contingent on allies meeting defense spending targets 3.

Analysis
The review converts US force posture in Europe from a standing commitment into a performance-linked contract, giving allies that denied basing and overflight during Operation Epic Fury the greatest near-term drawdown exposure. Spain's Rota naval base faces the sharpest risk: Washington's explicit singling out of Madrid creates direct leverage over destroyers central to NATO's missile defense mission. Whether the outcome is net reduction or redistribution toward Poland is genuinely uncertain within the six-month window. The Germany-Poland defense cooperation agreement signed the same day keeps rebalancing live, and moderate confidence in that assessment reflects the absence of public indicators that would allow discrimination before the review concludes. The review may instead function as a coercive spending instrument with no net reduction intended, which would leave European acquisition timelines and eastern flank planning baselines unchanged.
