WASHINGTON, D.C. — President Donald Trump announced September 18 that the United States has reached an agreement with Denmark and Greenland aimed at securing long-term military access to the Arctic island and preventing American adversaries from establishing a strategic foothold there.
Denmark and Greenland have confirmed an agreement, while emphasizing that it preserves their sovereignty. Signing and parliamentary approval procedures remain ahead.
For Americans, the potential benefit is a stronger northern defense position: lasting access for U.S. forces, opportunities to expand military operations and restrictions intended to keep rival powers from gaining strategically sensitive positions near North America.
Lasting access and restrictions on adversaries
U.S. officials describe the agreement as providing permanent access, basing and overflight rights, building on the defense relationship established under a 1951 treaty.
Trump said the arrangement would require express written American approval before U.S. adversaries could establish bases, maintain a military presence or make sensitive investments in Greenland.
The full terms have not yet been made public, leaving the precise scope and enforcement of those restrictions to be clarified.
The United States already operates Pituffik Space Base on the island. The announced agreement would support an expanded military presence and is intended to preserve American access even if Greenland eventually becomes independent, according to U.S. officials.
A defense agreement with allied support
Danish Prime Minister Mette Frederiksen and Greenland’s leader, Jens-Frederik Nielsen, have welcomed the agreement while stressing respect for Greenland’s interests and its people’s right to self-determination.
NATO has also welcomed the development as a step supporting security and cooperation in the Arctic.
Greenland previously figured in the statehood debate discussed by NIT in 2025. This agreement concerns defense cooperation; it does not make Greenland an American state or territory.
What comes next
The agreement is expected to be signed during the upcoming United Nations General Assembly gathering in New York. Parliamentary approval procedures in Denmark and Greenland are still required.
The announcement gives the Trump administration a diplomatic achievement to advance toward implementation. Its lasting value for American security will depend on the final terms, the military capabilities developed and how effectively the agreement prevents adversaries from gaining a foothold in the
