Donald Trump landed in Ankara late on Monday for a two-day NATO summit that officials privately fear could go badly off the rails, as the US president's increasingly foul mood and public outbursts threaten to overshadow talks with allies and leaders including Ukrainian President Volodymyr Zelensky and Syrian President Ahmed al‑Sharaa.
Anxiety inside NATO has been building for days as Trump has railed against alliance members over defence spending and questioned the value of the 75‑year‑old pact. His mood, described by multiple US officials to CNN as unusually dark, has sparked concern that he could derail discussions over the war in Iran, the reopening of the Strait of Hormuz and wider security issues with a fresh barrage of grievances or even threats to walk away from core commitments.
