Streets in Greenland and Denmark erupted as thousands protested Donald Trump’s bid to seize the Arctic island. From Nuuk to Copenhagen, banners declared “Greenland is not for sale” as U.S. lawmakers arrived amid rising tensions. Trump doubled down and announced sweeping tariffs on European allies who resist. The move has jolted NATO, triggered troop deployments, and alarmed Arctic nations. With 85% of Greenlanders opposing any U.S. takeover, the battle over this icy territory is fast becoming a global flashpoint.
