Vice President JD Vance and his wife are visiting an American military base in Greenland. The visit on Friday was revised after an initial three-day trip to the semi-autonomous Danish territory created uproar among Greenlanders and Danes who were irked that the travel plans were announced without previous consultation. Relations have been tense after President Donald Trump repeatedly suggested that the United States should in some form control the mineral-rich Danish territory. The one-day visit to the U.S. Space Force outpost at Pituffik, on the northwest coast of Greenland, has removed the risk of potentially violating diplomatic custom by sending a delegation to another country without an official invitation. Soon after arriving, Vance and his wife sat down with American troops stationed at the base for lunch. Vance briefly addressed U.S. troops at the start of a lunch, telling them he's "really interested in Arctic security. "As you all know, it's a big issue and it's only going to get bigger over the coming decades," Vance said.
