Just days before a major NATO summit, President Trump has thrown the transatlantic alliance into fresh uncertainty, declaring it “ridiculous” for the United States to continue what he called a “one-sided” relationship with the decades-old military pact. His comments have set nerves jangling across European capitals ahead of the gathering. Here is what he said, and why it matters.

The Comments

Trump wrote on his social media platform that NATO allies “were not there for us,” describing Washington’s relationship with the alliance as “not reciprocal.” The remarks come less than a week before NATO leaders are due to gather for a summit in Ankara, Turkey, raising the stakes for what was already shaping up to be a consequential meeting.

“Ridiculous.” “One-sided.” Trump’s words just days before a NATO summit have Europe bracing for confrontation.

The Ankara Summit

The upcoming summit will bring together all 32 NATO member states in the Turkish capital on July 7-8. Founded in 1949, the alliance has been credited with maintaining stability in Europe and containing Soviet, and later Russian, influence for decades. Trump’s comments cast a shadow over the summit before it has even begun.

Why Europe Is Worried

European leaders have long depended on American security guarantees as the backbone of the continent’s defence. Trump’s repeated questioning of the alliance’s value — and now his blunt characterisation of it as “one-sided” — fuels concerns that Washington’s commitment to European security could weaken, forcing European nations to reconsider their own defence spending and strategic autonomy.

The Broader Pattern

This is not the first time Trump has criticised NATO allies over burden-sharing and defence spending. But the timing — immediately before a summit — and the starkness of the language mark an escalation. European officials will be watching closely to see whether the rhetoric translates into concrete policy shifts at Ankara.

What’s at Stake

NATO’s cohesion has underpinned European security for over 75 years. Any serious rupture in the US-European relationship carries profound implications — for Ukraine’s ongoing war effort, for deterrence against Russia, and for the fundamental architecture of transatlantic security. The Ankara summit now carries far higher stakes than anyone anticipated.
