U.K. Prime Minister Keir Starmer says U.S. President Donald Trump’s threat to impose tariffs on allies over Greenland is “completely wrong.” He believes a trade war is in no one’s interest. Trump said Saturday that he would charge a 10% import tax starting in February on goods from eight European nations, including the U.K., because of their opposition to American control of Greenland, setting up a potentially dangerous test of U.S. partnerships in Europe. Greenland is a semiautonomous territory of NATO ally Denmark. The president indicated the tariffs were retaliation for last week’s deployment of symbolic numbers of troops from the European countries to Greenland.
