U.S. President Donald Trump has indicated he is seriously considering the possibility of withdrawing the United States from NATO, sharply escalating tensions with America's European allies amid growing disputes over the war against Iran.

In an interview with The Daily Telegraph, Trump said the question of U.S. membership in the alliance had moved ?beyond reconsideration? in response to what he described as a lack of support from NATO partners during the current Middle East conflict. His comments suggested that the issue could be revisited after the war concludes.

Trump's remarks came in the context of frustration in Washington over European governments refusing to join U.S. and Israeli military actions against Iran. He also pointed to allied reluctance to assist in efforts related to reopening the Strait of Hormuz, a key shipping route that has been heavily disrupted by Tehran's response to strikes.

The U.S. president repeated long-standing criticism of NATO, describing the alliance as a ?paper tiger? and arguing that its credibility is overstated. He also suggested that Russian President Vladimir Putin shares this view.

In addition, Trump used the interview to criticize the United Kingdom, questioning its military capacity and specifically targeting its naval capabilities. His remarks followed renewed disagreements with British Prime Minister Keir Starmer over London's refusal to support U.S. operations against Iran.

The interview was published shortly after U.S. Secretary of State Marco Rubio signaled that Washington may also reconsider its NATO relationship once the Iran conflict is resolved, adding further pressure on transatlantic relations already strained by differing positions on the war.

Trump's comments reflect a broader escalation in rhetoric between the United States and several European allies, with Washington increasingly critical of what it sees as limited cooperation during a period of heightened regional military confrontation.
