A little history of Greenland from Britannica: "At the start of the 21st century, there was growing support in Greenland for greater control of its foreign affairs. This arose partly in response to a 2004 agreement allowing the United States to upgrade its missile defense system at Thule Air Base. Inuit who had been forcibly removed from the area surrounding the base in the 1950s sued for the right to return, airing their grievances at the European Court of Human Rights. Some Greenlanders were wary of continued U.S. involvement because the United States had stored nuclear bombs on the island during the Cold War without Greenland’s knowledge, despite a Danish ban on such weapons; additionally, in 1968 a U.S. military aircraft carrying four hydrogen bombs had crashed near Thule."
