In a blistering exclusive interview with The Telegraph, President Trump has declared he is “strongly considering” pulling the United States out of NATO, branding the 77-year-old alliance a “paper tiger” after European allies – including the UK under Prime Minister Sir Keir Starmer – refused to join America’s military campaign against Iran or help reopen the Strait of Hormuz.
Trump told the newspaper the decision was now “beyond reconsideration,” adding: “I was never swayed by Nato. I always knew they were a paper tiger, and Putin knows that too, by the way.” He singled out Britain, mocking its naval capabilities and Starmer’s green-energy focus: “You don’t even have a navy. You’re too old and had aircraft carriers that didn’t work… All Starmer wants is costly windmills that are driving your energy prices through the roof.”
The row erupted after Iran effectively closed the Strait of Hormuz – through which 20 per cent of the world’s oil flows – in response to US-Israeli strikes launched on February 28. Allies have been reluctant to deploy warships, prompting Trump to accuse NATO of operating a “one-way street.”
Secretary of State Marco Rubio echoed the president on Fox News, warning that America would have to “re-examine” its NATO membership once the Iran conflict ends. “If Nato is just about us defending Europe if they’re attacked, but them denying us basing rights when we need them, that’s not a very good arrangement,” Rubio said. Trump later told The Telegraph he was “glad” Rubio had spoken out.
Starmer Fires Back: “This Is Not Our War”
Starmer moved quickly to reaffirm Britain’s commitment to NATO while drawing a firm line on the Iran conflict. “This is not our war, and we’re not going to get dragged into it,” he told The Telegraph, describing the alliance as “the single most effective military alliance the world has ever seen.” He signalled a pivot toward closer European cooperation “whatever the noise” from Washington.

The UK’s military vulnerabilities have only added fuel to the fire. On Tuesday, the First Sea Lord admitted the Royal Navy was not ready for war. Four of Britain’s six destroyers were out of service at the conflict’s start, forcing London to borrow a German warship to meet NATO obligations in the North Atlantic.
Any formal US withdrawal would require Congressional approval under 2023 legislation co-sponsored by Rubio himself. However, experts note Trump could still gut American participation by pulling troops, bases, and command support – effectively hollowing out the alliance without a full exit.
Trump is expected to deliver a national address on Wednesday evening outlining the Iran war’s status and, according to Reuters sources, to voice further disgust at NATO’s lack of reciprocity.
As oil prices spiral and recession fears mount, the standoff over the Strait of Hormuz has exposed raw fractures in the Western alliance. Whether Trump’s latest broadside is negotiation theatre or the beginning of America’s strategic retreat from Europe remains to be seen — but the “paper tiger” label has already left its mark.
