Italy’s Prime Minister Giorgia Meloni has openly challenged Donald Trump’s tariff threat on Europe over Greenland. Speaking from Seoul, Meloni called the move “a mistake” and warned it could fracture NATO unity at a critical moment. She backed U.S. focus on the Arctic but said European troop deployments were meant to counter hostile actors, not Washington. Meloni revealed she spoke directly to Trump and NATO’s chief, pushing for dialogue over escalation. With Greenland now a flashpoint in great power rivalry, Europe fears tariffs could spark a deeper transatlantic crisis.
