NATO Secretary General Mark Rutte sought to laugh off controversy after U.S. President Donald Trump publicly shared a private message from him on Truth Social. Speaking during a panel discussion at the World Economic Forum in Davos, Rutte acknowledged that private communications sometimes become public, before breaking into laughter and declining to comment further. He firmly refused to address the sensitive Greenland issue in public, saying he was working on it “behind the scenes.” Earlier, Trump had posted what he said was a personal text from Rutte praising his actions on Syria and expressing commitment to finding “a way forward” on Greenland. The revelation reignited debate over diplomatic norms, privacy between allies, and NATO’s role amid rising geopolitical tensions. Rutte’s light-hearted response contrasted with the seriousness of the Greenland row, which has strained U.S.-European relations. The episode highlights the unusual and often disruptive role social media continues to play in high-level international diplomacy.
