Trump’s NATO Comeback: How a Former Critic Helped Revitalize the Alliance in 2025

Trump’s Unexpected NATO Comeback: From Critic to Champion

Just this week, President Donald Trump made headlines with a surprisingly strong endorsement of NATO, signaling a dramatic shift from his earlier, often rocky relationship with the alliance. It’s a pivot that caught many off guard, considering how he used to slam NATO and even threatened to pull the U.S. out of the pact. But now? Trump’s singing a different tune — praising allies, lauding their patriotism, and touting a much stronger NATO than before.

A New NATO, a New Trump

I left here differently,” Trump told reporters after the 2025 NATO summit held in The Hague. “I left here saying these people really love their countries.” That’s a far cry from the fiery rhetoric that dominated his 2016 campaign and early presidency when he labeled NATO “obsolete” and complained bitterly that America was footing too much of the bill.

The change? NATO members collectively agreed to more than double their defense spending targets — from the longstanding 2% of GDP to a robust 5%. That’s a huge deal for an alliance that’s often been criticized for freeloading members.

But Trump’s shift isn’t just about the money. The atmosphere at this year’s summit was noticeably different. Gone was the tension and drama of previous years. Instead, Trump was warmly welcomed by Dutch royals, earned praise from NATO Secretary-General Jens Stoltenberg (who, in a lighthearted moment, jokingly called him “daddy”), and openly applauded European allies for stepping up their game.

“It’s not a rip-off, and we’re here to help them,” Trump said, highlighting a new tone of cooperation rather than confrontation.

From Bombs to Bonds: The Backdrop of Power

It’s impossible to ignore the timing of this change. Just before heading to The Hague, Trump came off a major foreign policy win — a precise U.S. strike that crippled Iran’s nuclear infrastructure, setting back Tehran’s program by years. Intelligence sources from both America and allied nations called it a masterstroke of strength and strategy.

“This wasn’t just a move against Iran,” said Giedrimas Jeglinskas, former NATO official and now chairman of Lithuania’s national security committee. “It was a signal to Russia, China, and others — a reminder of the West’s deterrence.”

Eastern and Northern European nations, still wary from years of Russian aggression, viewed the strikes as a significant restoration of Western resolve. Trump “came in from this power move,” Jeglinskas said, crediting the sophisticated weapons and bombers used as a symbolic rebuild of NATO’s deterrence narrative.

The Rocky Road to Today

It’s wild to think that just a few years ago, Trump was publicly attacking NATO. Back in March 2016, he famously called the alliance “obsolete” and griped that the U.S. was paying way more than its fair share.

“It’s costing us too much money,” he said then, “we’re paying disproportionately. It’s too much.”

And he didn’t hold back on criticizing NATO’s focus either. He called out the alliance for failing to prioritize the growing threat of terrorism — though later, he took credit when NATO created a chief intelligence post to address those concerns.

Once in office, Trump softened his stance somewhat but didn’t drop the pressure. “We strongly support NATO,” he declared after visiting U.S. Central Command. “We only ask that all members make their full and proper financial contribution.” The push to meet the 2% GDP target by 2024 remained a constant refrain.

Privately, however, the president warned that the U.S. might walk away if allies didn’t step up. “Now we are in World War III protecting a country that wasn’t paying its bills,” he said in reference to America’s commitments.

Despite the bluster, Trump called NATO a “fine-tuned machine” once he secured new spending commitments. But he also didn’t hold back on Germany, accusing it of being a “captive of Russia” thanks to the Nord Stream 2 gas pipeline.

Summits, Spats, and Showdowns

Trump’s NATO years were full of memorable moments — some less diplomatic than others. For example, French President Emmanuel Macron famously labeled NATO “brain-dead,” to which Trump fired back that NATO “serves a great purpose” and found Macron’s remarks “very insulting.”

There was also the drama with Canadian Prime Minister Justin Trudeau, who was caught mocking Trump on camera, prompting Trump to call him “two-faced.”

The president’s decision to pull 12,000 U.S. troops out of Germany added more fuel to the fire, citing Germany’s failure to meet defense spending goals.

One of Trump’s most controversial moments came when he suggested he might let Russia “do whatever the hell they want” to NATO countries that didn’t meet their financial obligations. That comment caused alarm bells to ring across Europe, triggering urgent talks on how to secure the alliance’s future without solely relying on the U.S.

A Surprising Summit: Calm and Cooperation

Fast forward to the 2025 summit in The Hague, and the vibe was almost unrecognizable. Trump’s hosts rolled out the red carpet. “He’s the man of the hour and the most important man in the world,” Jeglinskas said.

The blunt, sometimes brash diplomacy Trump brings—while still controversial—has undeniably shaken things up. “He’s brought in tectonic change to the alliance’s capabilities by… being himself,” Jeglinskas noted. “It’s a gift for the alliance.”

Why the Revitalization? Two Big Reasons

Experts agree that NATO’s recent revival boils down to two major factors:

  1. Russia’s 2022 invasion of Ukraine: This bold aggression by Moscow jolted the alliance into action, forcing member nations to rethink security and ramp up defenses.

  2. Trump’s relentless pressure: No matter how you feel about his style, his push for allies to increase their defense spending broke through years of complacency.

Matthew Kroenig, vice president at the Atlantic Council’s Scowcroft Center, summed it up: “President Trump is riding high this week with two major foreign policy victories.” Referring to NATO’s progress and the Iran strikes, Kroenig said, “It’s terrific. I hope he can keep it up.”

Kroenig added an interesting perspective: “Every president since Eisenhower has complained that NATO allies aren't doing their fair share.” So, while Trump’s approach might have been unorthodox, the underlying issue isn’t new.

Key Takeaways from Trump’s NATO Story

  • Diplomacy can change — even for critics. Trump’s transformation from NATO skeptic to advocate shows political dynamics can shift rapidly, especially when interests align.

  • Money talks, but so does power. Doubling defense spending targets from 2% to 5% of GDP marks a serious commitment by NATO members, driven partly by Trump’s tough talk but also by real security threats.

  • Leadership styles differ, but results matter. Trump’s blunt style ruffled feathers but pushed tangible reforms, showing that sometimes disruption can lead to progress.

  • Global security is a complex dance. The combination of geopolitical events — like Russia’s invasion of Ukraine and U.S. strikes on Iran — play huge roles in alliance cohesion.

Looking Ahead

Will Trump’s newfound friendship with NATO last? Only time will tell. But for now, the 2025 summit marks a high point in what’s been a rollercoaster relationship.

It’s a reminder that even the most contentious politics can lead to unexpected partnerships — especially when the stakes are as high as global security.
