NATO summit heads to Ankara with US-European rift over Iran and defence spending
Rutte met Trump June 24 ahead of the July 7-8 Ankara summit; US anger at allies who refused to join the Iran campaign; 5% GDP defence target being pushed
Summary
NATO Secretary General Rutte met President Trump on 24 June 2026, two weeks before the US-hosted alliance summit in Ankara (7-8 July). The summit arrives with a transatlantic rift sharpened by the Iran campaign: most European NATO allies declined to participate in the US-led strikes on Iran, drawing open US anger. Trump is pushing a 5% GDP defence spending target — double the current 2% guideline — and the Ankara summit is where that demand will reach heads-of-state level. A concurrent Trump-Meloni personal feud complicates the Italian-US relationship. Turkey's hosting reflects Ankara's central role in mediating both the Ukraine and Iran dossiers.
The split
Washington frames the Iran exclusion as proof that European allies are free-riders on US military power and must now compensate with hard spending commitments. European capitals — led by France, which has its own nuclear doctrine and its own Ukraine-first security calculus — argue that the Iran campaign was not an Article 5 matter and that 5% GDP is fiscally and politically impossible for most members. Stars and Stripes reports that US commanders privately question Article 5 reliability for allies who sat out Iran; that implicit conditionality is the subtext of every Ankara negotiation.
By the numbers
- July 7-8 — Ankara summit date.
- 5% GDP — US-pushed defence spending target (current guideline: 2%).
- June 24 — Rutte-Trump meeting date.
- 0 — European NATO allies that joined the Iran air campaign.
Why it matters
If the Ankara summit fails to produce a credible spending framework, it accelerates the bifurcation of NATO into a US-led combat tier and a European deterrence tier — a structural change that the Iran campaign has already begun in practice. The Article 5 conditionality subtext, if made explicit, would be the most significant NATO credibility crisis since the alliance's founding.
What to watch
- Whether a 5% GDP target (or a credible path) is agreed or deferred.
- Whether Trump explicitly conditions Article 5 on prior coalition membership.
- Whether Meloni and Trump repair their personal rift before or during the summit.
- Ankara's role — whether Turkey leverages its hosting position on S-400 or other outstanding disputes.
