NATO Secretary-General Mark Rutte enters the alliance’s summit in Turkey facing fresh pressure from U.S. President Donald Trump, whose demands have shifted from traditional defense spending targets to broader expectations of “loyalty.” Multiple reports say Rutte has spent much of his first two years in the role working to keep the United States engaged in NATO, including by addressing Trump’s concerns through persuasion efforts aimed at preventing threats to leave the alliance.

Earlier friction centered on allied defense spending levels, with Trump criticizing European countries for contributing too little compared with the United States. Sources note that this issue was addressed at a prior NATO summit, where allies committed to investment levels tied to GDP. However, the reporting says the focus now is less about funding amounts and more about converting those investments into usable military capabilities, particularly as European states express concerns about potential threats from Russia.

Rutte also reportedly met with Trump at the White House last month and used new messaging to reassure the U.S., including reference materials highlighting European spending, as the summit approaches.
