United States and Denmark sign agreement to establish two military bases in Greenland

The United States, Denmark, and Greenland signed a defence agreement on September 22, 2026, at the United Nations General Assembly in New York. The deal allows the US to open two new military bases in Greenland. One base will reopen at Narsarsuaq in the south, a site that was active during the Cold War. A second base will be built at Mestervig on the east coast. The agreement confirms that Denmark keeps sovereignty over Greenland. It also bans non-NATO countries from building military bases there. Currently, the US has only one base in Greenland, Pituffik Space Base, with around 150 staff. At the height of the Cold War, the US ran 17 bases there with more than 10,000 personnel. The deal follows months of pressure from President Trump, who had threatened to take control of Greenland.
