How are NATO allies pushing back against Trump’s Iran war demands?

President Trump is considering withdrawing the United States from NATO as European allies resist his demands for deeper military cooperation in the U.S.-Israel conflict with Iran. The standoff reflects a fundamental disagreement over the scope of NATO's mission and the extent to which member nations should be drawn into Middle East conflicts that fall outside the alliance's traditional European defense focus. Trump has used the NATO exit threat as leverage to pressure allies into supporting his Iran policy, a negotiating tactic that has intensified existing tensions over burden-sharing and defense spending within the alliance. European governments have signaled reluctance to expand military operations beyond their current commitments, citing concerns about escalation and the legal and political constraints on their own involvement. The dispute underscores how Trump's transactional approach to alliances is creating friction at a moment when NATO cohesion is already strained by broader debates over U.S. commitment to the alliance.
