Why Trump left NATO summit on a positive note after seething about Iran, Spain and Greenland

Trump’s NATO Summit: From Outrage to Optimism

Why Trump left NATO summit on a positive note after days of tension with European allies. European officials entered Wednesday’s NATO gathering with considerable apprehension. President Donald Trump had positioned himself just beyond the conference hall entrance, openly voicing his accumulated frustrations with the transatlantic alliance. His grievances spanned multiple issues, including the alliance’s decision not to transfer Greenland to American control and Spain’s reluctance to permit its military installations to support operations in the ongoing conflict with Iran—a confrontation Trump had previously warned could escalate once more.

Word of Trump’s complaints spread quickly among his fellow leaders. Many anticipated a harsh confrontation during the summit, though they harbored hopes that the worst might be avoided. Their concerns deepened when rumors circulated that Trump might announce an American withdrawal from NATO entirely. However, observers noted that the president’s demeanor behind closed doors proved considerably more measured than his public displays.

Inside the Conference Room

According to sources privy to the discussions, Trump refrained from mentioning Greenland during the meeting. Spain similarly escaped his criticism. His primary complaint centered on insufficient allied support regarding Iran. He expressed particular dissatisfaction with the agreement he had concluded with Tehran just three weeks earlier, characterizing it as completely broken following Iranian attacks on several vessels navigating the Strait of Hormuz.

Despite his frustrations, Trump stopped short of threatening to withdraw the United States from NATO—a move that, while technically possible, had worried European officials considerably. He appeared genuinely impressed when leaders outlined their efforts to increase defense investments, a development that NATO Secretary General Mark Rutte consistently credited to Trump’s persistent advocacy over many years.

One minor grievance Trump raised involved media access. The press had been excluded from observing the session. “They like the job I’m doing,” Trump reflected as the day concluded. “They said, ‘We love, sir, we love you.’ These are grown people saying that. Isn’t that nice?”

“Maybe they were trying to get to me,” he shrugged. “And, in a way, they did.”

While this characterization may have overstated the Europeans’ genuine sentiments, Trump demonstrated awareness that his counterparts might be flattering him. Under Rutte’s diplomatic guidance—himself known as a skilled Trump admirer—the generous praise seemed effective, even if some officials privately felt European dignity had suffered as a result.

Unexpected Developments

Hours later, Trump sat beside Ukrainian President Volodymyr Zelensky and revealed he was considering permitting Kyiv to produce its own Patriot missile interceptors domestically. This represented a significant shift for a leader who had publicly criticized Zelensky in the Oval Office just sixteen months previously.

“I just want to say there was tremendous love in that room,” Trump said before departing the summit.

The durability of this positive atmosphere remains uncertain. Trump had spent a G7 summit in France merely three weeks prior enthusiastically praising the very Iran agreement he now declared dead. Such diplomatic warmth often proves temporary. Nevertheless, even if these favorable sentiments endure long enough for Trump to reconsider his threats—including his privately suggested plan to reduce American military presence in Europe by one-third—the outcome could qualify as a victory.

This represented precisely what Rutte had hoped to achieve, despite the summit’s rocky beginning. It also fulfilled objectives Rutte had pursued throughout the past year, ever since Trump left the 2025 Netherlands summit appearing unusually amicable toward the alliance.

Rutte found an unexpected ally in Turkish President Recep Tayyip Erdoğan, whose leadership has periodically complicated NATO operations. Trump regards Erdoğan as a close friend and repeatedly emphasized that he attended the summit primarily because the Turkish leader was hosting it. This reluctant participation did not guarantee a particularly harmonious gathering.

Trump’s recent feuds added additional tension, including his ongoing dispute with Italian Prime Minister Giorgia Meloni. Before the summit, Trump shared a photograph of Meloni on social media accompanied by the caption: “RESTRAINING ORDER NEEDED.” Even during a Tuesday evening dinner where Trump and Meloni sat together sampling Turkish specialties such as pide flatbreads and manti dumplings, the tension between them appeared unresolved. Meloni described their relationship as “cordial” upon returning to her hotel.

Erdoğan, an authoritarian leader who has suppressed opposition, provided a stabilizing presence during the summit. His friendship with Trump helped ease several contentious moments. Ultimately, why Trump left NATO summit with optimism despite earlier frustrations came down to personal diplomacy and mutual respect among leaders who, despite their differences, recognized the value of the alliance.
