NATO Secretary-General Mark Rutte laid on the flattery with US President Donald Trump on Wednesday, pressing the case for a military alliance that the volatile U.S. leader has sharply criticized as the Pentagon reviews the size of the U.S. military footprint in Europe.

Axar.az reports, citing AP, Trump has repeatedly slammed NATO, arguing the U.S. carries more than its fair share of military spending. But his grievances have been louder since the Iran war, as he fumed over the fact that some member countries ignored his call to help him restart oil trade through the shuttered Strait of Hormuz.

“They weren’t too nice to us in our recent little military skirmish,” Trump said of NATO allies as he introduced Rutte during their Oval Office meeting.

Subsequently pressed on what key U.S. allies could do to get back on his good side, Trump responded, “Just be loyal.”

“We don’t need their money — we don’t need anything,” the president added. “We have the most powerful military in the world by far. But I just want loyalty.”

Trump has renewed his threats to leave the 77-year-old alliance, raising the stakes before the NATO leaders’ summit in Turkiye next month. But Rutte, who has become known as a Trump whisperer for his ability to charm the president, took on the now-familiar role of attempting to appease him anew.

Rutte pushed back gently against Trump’s complaints, saying, “I know there have been isolated cases about which you are really disappointed, but generally speaking, your European allies have been there with you.”

He also noted that 4,000 to 5,000 U.S. planes took off from bases in Europe before Iran and the U.S. agreed to a ceasefire.

Rutte gushed about Trump having been “very harsh” with defense contractors, saying, “I had one of them over in my office. He was still trembling.”

“This is your president, but also the leader of the free world, taking the leadership role, as is necessary,” Rutte told reporters in the Oval.

During the meeting, Rutte gave a presentation using three boards on easels, touting U.S.-NATO ties. Joining Trump were Hegseth, Vice President JD Vance and other top administration officials.

Nevertheless, a chief part of Rutte’s mission these days is keeping the U.S. in NATO, and he’s proven himself adept in the past at subduing Trump’s frustrations.

Rutte frequently credits Trump with getting NATO members to increase their defense spending. The president last year pressured leaders to agree to invest 5% of their GDP annually in defense by 2035.

“He is completely committed” to the NATO alliance, Rutte said after leaving the White House, though he added, “I expect allies to spend more to equalize with the United States.”
