Trump Floats Possible NATO Exit Over Allies’ Refusal to Join Iran War

During a March 17 Oval Office meeting with Irish Prime Minister Micheál Martin, President Donald Trump blasted NATO for refusing to participate in the U.S. war against Iran and said leaving the alliance is 'certainly something that we should think about,' adding, 'I don't need Congress for that decision.' He called NATO’s stance 'a very foolish mistake' and said he was 'not exactly thrilled' with the partnership after the alliance reiterated it is a defensive body with no plans to join an offensive campaign in Iran. In the same appearance, Trump embraced Israeli claims that overnight strikes killed two of Iran’s top security officials, said 'their leaders are gone,' and accused one unnamed official of being responsible for 32,000 protesters’ deaths, though Iran has not confirmed any such deaths and the casualty figure was not backed by evidence in the report. Trump also publicly derided outgoing National Counterterrorism Center director Joe Kent as 'very weak on security' and framed Kent’s resignation over the Iran war as 'a good thing' for his administration. These comments sharpen existing concerns among allies and national‑security experts about U.S. reliability in NATO and the extent to which Trump is willing to sideline internal dissent and stretch unverified claims to sell his Iran war to the public.
