NATO Secretary General Rutte Presses Trump on Alliance Commitments Ahead of Ankara Summit

NATO Secretary-General Mark Rutte met with President Donald Trump at the White House on June 25, completing a three-day Washington visit timed to the final preparations before the alliance's July summit in Ankara, Turkey ^[1][2]. The talks addressed a cluster of unresolved disputes: allied reluctance to support Operation Epic Fury, the U.S. military operation against Iran that began Feb. 28; a Pentagon-ordered review of American troop deployments across Europe; and the broader question of whether NATO members are meeting the 5% of GDP defense spending target Trump extracted at last year's summit in The Hague ^[2][17][4].

The immediate trigger for the Washington visit was the Pentagon's announcement, made by Defense Secretary Pete Hegseth at a NATO defense ministers meeting in Brussels, of a six-month review of U.S. force posture in Europe ^[17][2]. That review, Hegseth said, will assess how individual allies responded when the United States sought basing and overflight rights for Operation Epic Fury, the name the U.S. government assigned to the joint American-Israeli strikes on Iran ^[16][18]. Hegseth told his counterparts that future troop deployments and base locations in Europe could be altered depending on how allies aligned with Pentagon priorities during the Iran conflict, adding, "It's a review that some countries will fail and others will pass with flying colors." The review could have significant implications for the roughly 80,000 U.S. troops currently deployed in Europe.

The Ankara summit, scheduled for July 7-8 at Turkey's Beştepe Presidential Compound, is the 36th NATO summit and the second Turkey has hosted ^[6][8]. Rutte's Washington visit is part of the final preparations for that summit, NATO spokesperson Allison Hart confirmed, noting the meeting will focus on how allies are delivering on commitments made at The Hague, including defense investment, defense industrial production, and continued support for Ukraine. Following their commitment last year to invest 5% of GDP in defense, European allies and Canada increased their core defense investment by $139 billion in nominal terms in 2025, with some allies on course to reach the 5% target in 2026 ahead of schedule. Whether that trajectory satisfies the Trump administration before the summit remains the central open question.

Operation Epic Fury frames the political stakes directly. Since Feb. 28, 2026, the United States and Israel have been at war with Iran, following U.S.-Israeli airstrikes targeting Iranian military and government sites. Those attacks were launched during Iran-U.S. negotiations toward a nuclear agreement. The initial American strikes were designated Operation Epic Fury by the U.S. government. Several NATO allies declined to authorize use of their bases for combat missions in support of the operation. Spain drew particular criticism for refusing access to its bases for operations in Iran. The status of the U.S. naval presence at Rota, a key base hosting destroyers that support NATO's missile defense mission, remains unresolved. Trump went so far as to threaten to leave NATO or impose penalties on individual members over their decisions to deny the United States use of military facilities.

After NATO allies refused to back the Iran campaign, which Trump began without prior consultation, Trump openly questioned whether the United States should honor NATO's mutual defense commitment and said he was considering leaving the alliance. U.S. Ambassador to NATO Matthew Whitaker stated publicly that Trump is "reevaluating" U.S. membership, including American support for the European defense effort in Ukraine ^[3]. Secretary of State Marco Rubio echoed Trump's posture, telling Fox News that the United States will reexamine its relationship with the alliance and that the decision ultimately rests with the president. Article 5 of the North Atlantic Treaty, the collective defense provision, has no mechanism that compels an ally to participate in offensive operations outside NATO territory, a legal distinction that complicates the administration's complaint about allied non-participation in Iran.

Following his White House meeting, Rutte met with members of Congress on Capitol Hill Thursday, then concluded the visit with a speech and discussion at the Atlantic Council outlining his expectations for the Ankara summit. Despite the friction, Rutte has maintained functional ties with senior Pentagon officials, and Hegseth spoke warmly of his leadership at the Brussels defense ministers meeting. White House spokesperson Olivia Wales told POLITICO that Trump maintains "a strong relationship" with Rutte but that the president remains firm that NATO countries must assume greater responsibility for their own defense and that allies should have supported the United States during Operation Epic Fury [POLITICO]. The Ankara summit opens in six days, and the procedural pressure for a consolidated allied position, both on defense spending targets and on the Iran precedent, will intensify as leaders arrive.
