U.S. President Donald Trump said in an April 1 interview with The Telegraph that he is strongly considering withdrawing the United States from NATO after allies declined to support U.S. military action against Iran. His remarks followed comments from U.S. Secretary of State Marco Rubio suggesting Washington may need to reassess its NATO ties after the Iran conflict.

The remarks come on top of a series of threats from the Trump administration since taking office in 2025 to withdraw from NATO or disregard Article 5's mutual defense obligations, heightening tensions within the alliance. U.S. calls for European support in military operations against Iran have met uniform resistance, with Spain, France and Italy denying overflight and basing access. Allies also declined requests to assist in reopening the Strait of Hormuz, prompting further frustration from the U.S. administration and reinforcing longstanding concerns about NATO's operational reliability.
