The cost of keeping the most powerful military committed to defending Europe
In the long arc of postwar order, few institutions have carried more symbolic weight than NATO, the mutual defense pact that bound Western democracies together through decades of Cold War and beyond. Now, on the eve of the alliance's annual summit in Turkey, NATO Secretary-General Mark Rutte traveled to the White House to perform a delicate act of diplomatic preservation — meeting with a president who has openly questioned whether America should remain part of the 77-year-old arrangement at all. The visit is less a negotiation between equals than a careful tending of a relationship upon which the security architecture of an entire continent depends.
- Trump's frustrations with NATO have reached a new intensity after allied nations refused to support his Iran strategy — a war launched without consulting them — adding a fresh grievance to his long-standing complaint that America pays too much for Europe's defense.
- U.S. Defense Secretary Hegseth traveled to NATO headquarters in Brussels and delivered a pointed warning: the Pentagon will spend six months reviewing whether American troops should remain stationed across Europe at all.
- Rutte, who has cultivated a reputation as a 'Trump whisperer,' arrived armed with his familiar tools — Fox News appearances, effusive praise, and text messages that mimic the President's own capitalization habits — in a bid to prevent the alliance from fracturing before the Ankara summit.
- Europe's five largest members gathered in Berlin to coordinate their approach, with Macron cautiously declaring a 'moment of reconvergence' between the two sides of the Atlantic, even as the underlying tensions remain unresolved.
- The Ankara summit now looms as a critical test of whether strategic flattery and spending pledges can hold together an alliance whose most powerful member is openly weighing the door.
Mark Rutte arrived at the White House on Wednesday with a task he has performed before: calming an American president who has spent weeks threatening to abandon the military alliance Rutte leads. The visit came two weeks before NATO's annual summit in Turkey, now overshadowed by Trump's renewed threats to withdraw from the 77-year-old organization.
Trump's grievances had sharpened after the Iran war. He had pressed allied nations to help reopen oil trade through the Strait of Hormuz, and when several declined, his resentment deepened. The war itself — launched jointly with Israel on February 28 — had caught NATO members off guard; they had not been consulted beforehand, and some had publicly criticized the strategy. Days before Rutte's visit, Defense Secretary Pete Hegseth traveled to NATO headquarters in Brussels and announced a six-month Pentagon review of American military forces in Europe, while criticizing allies for refusing to allow U.S. use of European bases against Iran.
Rutte had become known in diplomatic circles as a Trump whisperer. This was his fifth White House visit since Trump returned to office. The night before the meeting, he appeared on Fox News — a network Trump watched closely — praising the President as the leader of the NATO alliance and expressing full support for his Iran policy. His methods had occasionally raised eyebrows: he had once called Trump 'daddy' at a NATO summit, and sent text messages mimicking the President's habit of randomly capitalizing words for emphasis. Trump had posted several of them publicly on social media.
Meanwhile, Europe's five largest NATO members gathered in Berlin to prepare for the Ankara summit. German Chancellor Merz said the summit should signal European willingness to support an Iran peace deal. French President Macron was cautiously optimistic, describing 'a moment of reconvergence between the Europeans and the Americans.'
The stakes were considerable. NATO had been founded in 1949 on a mutual defense pledge invoked only once — after September 11 — and now its most powerful member was questioning whether it wished to remain. Rutte's task was to convince Trump that the alliance was still worth preserving, likely by crediting him with pushing member nations toward a commitment of five percent of GDP on defense by 2035. Whether flattery and selective agreement would prove sufficient remained an open question as the summit approached.
Mark Rutte arrived at the White House on Wednesday afternoon with a familiar task: soothing an American president who had spent weeks threatening to dismantle the military alliance Rutte leads. The NATO Secretary-General's visit came two weeks before the alliance's annual summit in Turkey, a gathering now shadowed by Trump's renewed threats to withdraw from the 77-year-old organization altogether.
Trump's frustrations with NATO have been building for months, but they sharpened considerably after the Iran war. The President had pressed allied nations to help him reopen oil trade through the Strait of Hormuz, a strategic waterway that had been shuttered. When several member countries declined to participate, Trump's resentment deepened. He had long argued that the United States bore an outsized burden of NATO's military costs. Now he was adding a new grievance: allies who refused to support his military ambitions without being consulted first.
The tensions had spilled into the open just days earlier when U.S. Defense Secretary Pete Hegseth visited NATO headquarters in Brussels and delivered a sharp rebuke. Hegseth announced that the Pentagon would spend the next six months reviewing the size and scope of American military forces stationed across Europe. He also criticized allies for refusing to allow the U.S. to use European bases for operations against Iran. The war itself, launched jointly with Israel on February 28, had caught NATO members off guard. They had not been consulted beforehand, and some had publicly criticized Trump's strategy.
Rutte had become known in diplomatic circles as a Trump whisperer—someone with an almost preternatural ability to calm the President's grievances through a combination of flattery and strategic agreement. This was his fifth visit to the White House since Trump returned to office last year. On Tuesday evening, the night before his in-person meeting, Rutte had appeared on Fox News, a network Trump watched religiously. He praised the President repeatedly, calling him the leader of the NATO alliance and expressing complete support for his Iran policy. When addressing Trump's complaints about allied use of European bases, Rutte dismissed them as isolated incidents.
Rutte's methods had proven effective, if sometimes eyebrow-raising. The previous year, he had referred to Trump as "daddy" during a NATO summit. He had also sent Trump text messages dripping with admiration, deliberately mimicking the President's habit of randomly capitalizing words for emphasis. "Europe is going to pay in a BIG way, as they should, and it will be your win," one message read. Trump had shared it publicly on social media. In January, Rutte sent another message that closed with "Can't wait to see you. Yours, Mark." Trump posted that one too.
Meanwhile, the five largest European NATO members—Germany, France, Britain, Italy, and Poland—had gathered in Berlin on Wednesday to prepare for the Ankara summit. Rutte joined them remotely. German Chancellor Friedrich Merz told reporters that the summit should signal European willingness to support an Iran peace deal if conditions allowed. French President Emmanuel Macron struck a more hopeful note, saying "we are in a moment of reconvergence between the Europeans and the Americans" and expressing hope that the trend would continue.
But the underlying reality was stark. Trump had already stunned European allies the previous year by threatening to annex Greenland, a semiautonomous Danish territory. The Pentagon's warning that it might reduce its military footprint in Europe represented another seismic shift for the 32-member alliance. NATO had been founded in 1949 as a bulwark against Soviet threats, built on a mutual defense pledge: an attack on one member was an attack on all. That commitment had been invoked only once, in 2001, when the alliance rallied to support the United States after the September 11 attacks. Now, the alliance's most powerful member was questioning whether it wanted to remain part of the arrangement at all.
Rutte's task on Wednesday was to convince Trump that NATO remained worth preserving. He would likely credit the President with pressuring member nations to increase defense spending—Trump had pushed leaders to commit to investing five percent of their GDP annually on defense by 2035, a significant escalation. Whether flattery and selective agreement would be enough to keep the alliance intact remained an open question as the Ankara summit approached.

The Hearth Conversation Another angle on the story
Why does Rutte keep visiting Trump if the relationship is already so strained?
Because the alternative—Trump actually leaving NATO—would reshape European security overnight. Rutte's job is to make staying in the alliance feel like Trump's idea, his victory.
But doesn't the flattery feel obvious? Calling him "daddy," capitalizing random words in texts?
It works. Trump shares those messages publicly because they make him feel seen and appreciated. For Rutte, that's not humiliation—it's the cost of keeping the most powerful military in the world committed to defending Europe.
What changed with the Iran war? That seems to be the real breaking point.
Trump didn't ask permission. He launched it with Israel and then expected allies to help him with the Strait of Hormuz. When they said no, he felt betrayed. To him, that's proof NATO doesn't show up for America.
Is there actually a chance he leaves?
The threats are real enough that European leaders are preparing for it. But Trump also likes being the center of attention, being courted. Rutte understands that. The question is whether flattery can outlast genuine policy disagreements.
What does the Pentagon review actually mean?
It means they're seriously considering pulling troops out of Europe. That's not a bluff. If it happens, the entire post-Cold War security architecture collapses.
So the Ankara summit is essentially a last-ditch negotiation?
It's a moment where Europe has to convince Trump that NATO serves his interests. Macron's talking about "reconvergence." Merz is signaling willingness on Iran. They're all trying to give Trump something he can claim as a win.
