At the NATO summit in Ankara, Turkey, Canadian Prime Minister Mark Carney said that President Donald Trump has "won the argument" on NATO defence spending, crediting years of sustained US pressure with persuading Canada and European allies to shoulder a greater share of the alliance's security costs. The comment is notable because Carney has been a frequent and vocal critic of Trump on trade and other matters, making his public endorsement on this issue a significant shift in tone.

Carney said he had spoken with Trump by phone before the summit and told him that member states increasingly accept the need to raise military spending in the face of continued security threats from Russia. He acknowledged that Trump's long-running campaign for allies to spend more was "gaining momentum", even as he has repeatedly clashed with the president over tariffs on Canadian goods and Trump's suggestions that Canada become the 51st US state. The remarks follow the 2025 NATO summit in The Hague, where alliance leaders agreed to a new target of spending 5% of GDP on defence and security by 2035, more than double the long-standing 2% benchmark.
