Greenland and Denmark say a U.S. security deal will preserve sovereignty.

Greenland and Denmark said an agreement in principle would allow a significant U.S. military presence and prevent adversarial powers from establishing bases on the Arctic island. Reuters reported that details were not public and that a signing was expected around the United Nations General Assembly.

Greenlandic and Danish officials said the arrangement respects sovereignty and Greenlanders’ right to self-determination. Trump characterized the deal as giving the United States “permanent control,” but the public record did not establish that scope; NATO welcomed the agreement as supporting security, stability and cooperation.
