The United States, Denmark, and Greenland have signed a security agreement to strengthen U.S. military presence in Greenland. This agreement marks the end of prolonged discussions about the future of the Danish territory.
President Trump, Greenland Premier Jens-Frederik Nielsen, and Danish Prime Minister Mette Frederiksen signed the agreement in New York during the United Nations General Assembly. The White House shared the details of the deal soon after the signing.
Key Features of the Agreement
The agreement maintains Greenland’s sovereignty, part of the Kingdom of Denmark, while granting the U.S. significant access to the island’s airspace and land. It includes provisions to expand the current Pituffik Space Base, which serves as a missile early-warning system. Additionally, the U.S. can establish new bases at Narsarsuaq and Mestersvig, separated by about 950 miles. All parties can propose new “defense areas” with mutual approval.
This agreement, without an expiration date, prevents non-NATO countries from building bases in Greenland without consent from all parties. It remains valid even if Greenland gains independence from Denmark, and it implements strict measures against foreign investments by non-NATO and non-EU entities, aimed mainly at China and Russia.
Changing Arctic Security Dynamics
Greenland and Denmark leaders highlighted that the agreement reflects evolving security needs in the Arctic. President Trump previously showed interest in acquiring Greenland, causing tension among NATO allies.
“We’re going to have a tremendous relationship, a secure relationship, and we look forward to it,” Mr. Trump stated. “We’ll be working very hard and very much in conjunction with each other, and it’s just a real honor to be here.”
Nielsen acknowledged the changes since a 1951 security pact and recognized the long-term security threats highlighted by President Trump. He affirmed that the agreement clarifies Greenland’s loyalty in the future.
Frederiksen emphasized the respect for Denmark’s territorial integrity and Greenland’s self-determination rights in the deal.
Speech at the United Nations General Assembly
Before signing the agreement, President Trump addressed the United Nations General Assembly, outlining the U.S. plans to build additional bases in Greenland. He described Denmark as an “incredible, beautiful country” and underscored the agreement’s role in defending the American and European continents.
President Trump assured that no adversary of the U.S. would be allowed to establish a military presence or make significant investments in Greenland without explicit written permission.
