Trump Threatens to Leave NATO Over Iran. His Own Officials Say It Is Not Happening

Trump told The Telegraph this week that NATO is “beyond reconsideration” and that he “always knew they were a paper tiger.” Within hours, Finland’s president was on the phone with him. Within a day, Republican senators were publicly contradicting him. The Trump NATO withdrawal threat is the loudest it has ever been. The evidence it is real is close to zero.

The Iran war has put the NATO alliance under pressure that would have been unthinkable two years ago. Trump has spent weeks furious that European allies declined to join the US military campaign against Tehran, and his rhetoric has escalated with each week the campaign continues. But the gap between what he says and what the administration is actually doing inside the alliance is, according to every official who spoke to reporters this week, enormous.

NATO diplomats said the US has not started any debate inside the alliance and has issued no specific directives about Washington’s role. A senior Senate aide said the Trump administration has not notified Capitol Hill of a pending pullout. Talk around the Pentagon of withdrawing from the alliance is, in one defense official’s word, mum. “No evidence it is real,” the Senate aide said.

The Strait of Hormuz conflict is the backdrop. Trump wants NATO allies, particularly France and Britain, to help the US manage Iran’s blockade of the strait. European governments have so far refused to join what they see as Washington’s war of choice. Trump’s NATO threats, according to two NATO diplomats who were granted anonymity, are designed to force visible action from those allies rather than signal genuine intent to leave. His bluster, one diplomat said, “rarely translates into a structural break with NATO.”

The legal obstacles alone would make a fast exit nearly impossible. A 2023 law requires a two-thirds Senate vote before the US can leave NATO. That legislation was co-sponsored in the Senate by Trump’s own Secretary of State, Marco Rubio. Senate Minority Leader Chuck Schumer posted this week that the Senate will not vote to leave NATO and directly credited Rubio’s legislation for blocking unilateral withdrawal. Republican Senator Mitch McConnell joined Democrat Chris Coons in a bipartisan statement saying flatly that the US “will remain” in NATO.

Trump’s Iran war decision has also baffled some of his own former officials. After spending a year pressuring Europeans to take more responsibility for their own continent’s defense, threatening to abandon the alliance the moment they decline to join a Middle East campaign strikes even sympathetic observers as strategically incoherent. One former Trump administration official said it would be “such a major setback” to the longer goal of getting Europeans to spend more on their own defense.

Republican defense hawk Don Bacon put it more bluntly: “If he really means to pull us out of NATO, I think his presidency will never recover.”

The alternative Europeans fear most is not a formal withdrawal but something quieter. Trump could stay inside NATO while starving it of senior attention and military assets, leaving the alliance technically intact but practically hollow. A German official said it directly: “With Trump in office, NATO is worthless. We might have NATO, but we no longer have an alliance.”

Finnish President Alexander Stubb, who has built a reputation as one of Europe’s most effective Trump interpreters, dialled Washington within hours of the Telegraph interview and called the resulting conversation “constructive.” That description, coming from Stubb, carries weight. It suggests the call was not a confrontation and that Trump, whatever he told the newspaper, did not repeat his most extreme positions to a head of state he respects.

The White House issued a careful statement: Trump has made his disappointment with NATO clear, and “the United States will remember.” That is not the language of withdrawal. It is the language of leverage.

US NATO 2026 policy is, in practice, the same as it was before the interview. The threat is real enough to rattle allies and generate headlines. The structural conditions required to act on it – congressional notification, Senate votes, legal challenges from Democrat-led states – remain firmly in place. And the officials who would have to begin that process say they have received no instruction to do so.

The paper tiger comment may end up describing something other than NATO.
