Washington — The United States, Denmark, and Greenland have formalized a new security arrangement to enhance U.S. military presence in Greenland, strategically located in the North Atlantic. This agreement, signed after long-standing tensions concerning the future of Greenland, was concluded at the United Nations General Assembly in New York.
President Trump, Greenland Premier Jens-Frederik Nielsen, and Danish Prime Minister Mette Frederiksen were present for the signing ceremony. The White House has shared the contents of the deal, which underscores Greenland’s sovereignty while allowing the United States broad access to its airspace and territory.
The agreement allows expansion of the Pituffik Space Base, a key U.S. military installation serving as an early-warning system for missile threats. It also permits the establishment of bases at Narsarsuaq and Mestersvig, two sites separated by approximately 950 miles. Additional “defense areas” may be proposed by any party, requiring mutual approval.
Importantly, the deal lacks an expiration date and ensures that non-NATO countries cannot set up bases on the island unless all parties agree. The agreement will remain effective even if Greenland achieves independence from Denmark, targeting foreign investments from China and Russia.
Officials from Greenland and Denmark highlighted this deal as reflective of the evolving security dynamics in the Arctic region. President Trump, previously criticized for considering acquisition of Greenland, expressed optimism about the enhanced relationship.
“We are going to have a great and secure relationship. Working together is an honor,” President Trump stated.
Greenland Premier Nielsen acknowledged changes since the 1951 security pact that the new deal amends. He assured Greenland’s loyalty to the arrangement by detailing the significance of addressing long-term security challenges.
Danish Prime Minister Frederiksen reiterated the respect for Denmark’s territorial integrity and Greenland’s right to self-determination.
Speaking at the U.N. General Assembly, specifically before the signing, President Trump explained the deal facilitates additional military bases in Greenland. The U.S. holds an operational base there already. He emphasized,
“This agreement provides permanent control of security matters necessary for defending the American continent, Europe, and beyond. No adversary will be permitted to establish a military presence or make sensitive investments without our approval.”
