President Trump, Danish Prime Minister Mette Frederiksen, and Greenland Premier Jens-Frederik Nielsen signed a new security agreement on the sidelines of the United Nations General Assembly in New York. The deal amends the 1951 defense pact and gives the United States broad military authority and permanent access to Greenland, addressing growing strategic competition in the Arctic.

Key elements of the agreement include:

• Military Expansion: The U.S. is permitted to expand the existing Pituffik Space Base and establish additional defense areas at Narsarsuaq and Mestersvig, with the option for any of the parties to propose more bases as needed.

• Exclusion of Adversaries: The accord blocks non-NATO countries from building military bases on the island without the joint agreement of the U.S., Denmark, and Greenland. It also intensifies the screening of foreign investments from outside NATO and the European Union to block influence from nations like China and Russia.

• Sovereignty and Permanence: While President Trump described the arrangement as giving the U.S. “permanent control over security and all other needs” on the territory, both Danish and Greenlandic leaders emphasized that the pact formally respects the territorial integrity of the Kingdom of Denmark and Greenland’s right to self-determination. The deal has no expiration date and would remain in effect even if Greenland eventually votes for full independence.
