The president made a blistering statement after meeting with the NATO secretary-general, while the White House said the US could quit

US President Donald Trump has once again lashed out at NATO over the inaction of European allies during the war with Iran. The sharp rebuke came after a meeting with SecretaryGeneral Mark Rutte in Washington on Wednesday.

"NATO WASN'T THERE WHEN WE NEEDED THEM, AND THEY WON'T BE THERE IF WE NEED THEM AGAIN," Trump posted on Thursday on his social media platform Truth Social.

Trump's anger follows weeks of criticism of European NATO members for what he sees as their refusal to support US efforts, particularly in opening the strategic Strait of Hormuz effectively closed by Tehran.

Commenting on the closed-door talks with the US president, Rutte described the exchange as a "very frank, very open" discussion between "two good friends." He said in a Thursday interview with CNN, however, that Trump was "clearly disappointed" that US allies had refused to take part in the Iran war. Asked multiple times if Trump had said if he would leave the alliance, Rutte did not answer directly.

Also on Thursday, Bloomberg reported, citing a senior NATO official, that during the meeting Washington requested concrete commitments from European allies to secure the Strait of Hormuz, asking them to present plans to ensure navigation through the waterway within days.

Rutte has faced criticism in Europe for his perceived deference toward Trump. During a joint press appearance last year, he jokingly called the US president "Daddy," drawing media attention and ridicule.

European NATO members have largely resisted US calls to join the war with Iran. While recognizing the strategic importance of the Strait of Hormuz, officials from Spain, Germany, the EU, and other allies have declined to deploy forces, expand missions, or grant access to their bases and airspace, emphasizing defense and de-escalation over wider involvement.

Ahead of the latest meeting between Rutte and Trump, White House Press Secretary Karoline Leavitt told journalists that a possible US withdrawal from the bloc is "something the president has discussed." She also said that Trump could raise the issue with Rutte.

Last week, US War Secretary Pete Hegseth said the future of NATO was uncertain, and that Washington is currently unable to reaffirm its commitment to collective defense. He cited Trump as saying that "you don't have much of an alliance if you have countries that are not willing to stand with you when you need them."
