NATO Secretary-General Mark Rutte met with President Donald Trump at the White House on April 8, following criticism by Trump of the alliance’s lack of support for recent U.S. military operations against Iran.

Members of the alliance have been reluctant to send their forces to assist in combat operations against Iran. Throughout the Middle East conflict, several NATO member nations have also denied U.S. forces access to military bases and overflight of their airspace on the way to conduct strikes against Iran.

In a post on Truth Social after the meeting, Trump indicated that he was still unhappy with the treaty group.

“NATO WASN’T THERE WHEN WE NEEDED THEM, AND THEY WON’T BE THERE IF WE NEED THEM AGAIN. REMEMBER GREENLAND, THAT BIG, POORLY RUN, PIECE OF ICE!!!” Trump wrote.

The White House has not yet provided a readout or additional details on the two leaders’ discussion.

The president has raised the prospect of pulling the United States out of the alliance in the past.

“It’s quite sad that NATO turned their backs on the American people over the course of the last six weeks, when it’s the American people who have been funding their defense,” White House press secretary Karoline Leavitt said at a news briefing hours before Rutte’s visit.

Earlier Wednesday, Leavitt said Trump’s meeting with Rutte, which was closed to reporters, would entail “a very frank and candid conversation.”

When asked about Trump’s threat of withdrawing from NATO, Leavitt said, “I think it’s something the president will be discussing in a couple of hours.”

During the news briefing, Leavitt relayed a comment from Trump indicating that he considered the Iran conflict a test that NATO failed.

At the moment, the Iran conflict is paused.

In a post at 6:32 p.m. ET on April 7, Trump announced that he had agreed to a two-week ceasefire with Iran. Trump had threatened the widespread destruction of Iran’s energy sector and other key infrastructure if Iranian forces did not agree to cease attacks on the Strait of Hormuz by 8 p.m. on April 7.

Along with announcing what is planned to be a two-week pause in fighting, Trump said he had received a 10-point proposal from Iran to reach a broader, lasting settlement.

During a Pentagon news briefing on April 8, Secretary of War Pete Hegseth thanked Israeli forces for their role in the offensive operations against Iran.

“To our Israeli allies, thank you for being a brave, capable, and willing ally on this battlefield,” Hegseth said. “The rest of the world and the rest of our so-called allies saw what real capabilities look like. They should take some notes.”
