NATO’s leaders gather in Ankara on Tuesday and Wednesday as European members try to manage tensions with U.S. President Donald Trump over disputes involving Iran and Greenland and broader questions about U.S. commitments to the alliance. Multiple outlets describe a six-month period of friction between Washington and its European partners, with the U.S. pressing allies to increase defense spending and signaling a reduction in some commitments. NATO Secretary General Mark Rutte says allies are expected to present “clear, concrete and credible” plans to reach defense spending targets, including the 5% benchmark, and that the summit is aimed at demonstrating Europe’s intent to deter any Russian aggression.

Ahead of and during the summit run-up, reporting focuses on Trump’s public criticisms of allies and renewed disputes connected to the Iran war and Greenland. Several sources say Trump re-commits to the alliance during the summit after initial moments of discord, and that NATO leaders project unity despite continuing disagreements that also involve trade and Ukraine. The meeting is also described as a venue for arms-related announcements and deals as Europeans seek to show they are stepping up capacity.
