NUUK, Greenland – The United States, Denmark and Greenland have reached an agreement to strengthen security in the Arctic and North Atlantic, opening the way for a larger U.S. military presence on Greenland without transferring sovereignty over the island.
President Donald Trump announced the agreement Sept. 18, describing it as giving the United States permanent control over security and other defense needs in Greenland. Denmark and Greenland confirmed that an agreement had been reached but said it still needs to be signed and pass the required parliamentary procedures before entering into force.
The emerging arrangement falls short of Trump’s earlier calls for the United States to acquire Greenland, a proposal that had generated opposition in Denmark and Greenland and concern among other NATO members.
Sovereignty remains with Denmark and Greenland
Danish Prime Minister Mette Frederiksen said the agreement recognizes the sovereignty and territorial integrity of the Kingdom of Denmark as well as the Greenlandic people’s right to self-determination.
Greenland’s Prime Minister Jens-Frederik Nielsen said the agreement recognizes Greenland’s interests and strengthens security for Greenland, Denmark, the United States and the wider Western alliance.
Greenland is an autonomous territory within the Kingdom of Denmark. Its government has responsibility for many domestic matters, while Denmark retains responsibility for areas including foreign policy and defense.
The announced security arrangement does not transfer Greenland to the United States.
The Danish and Greenlandic governments said the three sides expect to sign the agreement during next week’s United Nations General Assembly in New York. Parliamentary procedures in Denmark and Greenland must then be completed before it can take effect.

Washington seeks a larger military footprint
The United States already maintains a major military installation in Greenland at Pituffik Space Base, formerly Thule Air Base.
The base supports missile warning, missile defense and space-surveillance activities and has operated under the broader framework of the 1951 Defense of Greenland agreement between the United States and Denmark.
The new arrangement is expected to expand the scope of U.S. military activity.
A U.S. State Department official said the agreement would provide permanent U.S. access, basing and overflight rights and allow the United States and its allies to make certain sensitive investments on the island. The official said non-NATO countries would be prevented from establishing military bases in Greenland.
Trump said the United States would begin developing a larger military presence in appropriate parts of Greenland.
The exact number, location and nature of any new facilities had not been publicly established when the agreement was announced.
China and Russia are central to the security concerns
The agreement is also intended to restrict the military and strategic presence of countries viewed by Washington and its allies as potential adversaries.
A U.S. official said the arrangement would prevent non-NATO countries from establishing bases in Greenland and would restrict sensitive investments without U.S. approval. China and Russia were specifically identified in reporting about the agreement.
Greenland’s geographic position gives it importance for monitoring activity across the North Atlantic and Arctic approaches to North America.
The island lies between North America and Europe and is strategically positioned near routes connecting the Arctic, the North Atlantic and the Norwegian Sea.
The United States has therefore maintained military facilities there since the Second World War and the Cold War.
Agreement follows months of tension
The agreement follows months of tension between Washington and Copenhagen over Trump’s demands for greater U.S. control of Greenland.
Trump had repeatedly argued that Greenland was important to U.S. national security and had previously raised the possibility of acquiring the territory. He also declined to rule out using military force to obtain it, alarming Denmark and other NATO allies.
The latest arrangement instead provides a framework for expanded U.S. defense activity while leaving Greenland under Danish sovereignty.
The shift followed negotiations involving officials from the United States, Denmark and Greenland.
The Danish government described the emerging pact as an agreement that strengthens common security in the Arctic and North Atlantic while maintaining the Kingdom’s sovereignty and Greenland’s right to self-determination.
Existing U.S. access provides the foundation
The United States already has extensive military rights in Greenland.
The 1951 Defense of Greenland Treaty established the legal basis for U.S. defense activities on the island. The current agreement would build on that existing relationship rather than create an American territorial possession.
The distinction is important because Trump’s political language about Greenland has previously centered on acquisition and control, while the agreement announced this week concerns security cooperation and military access.
Reuters reported that negotiators had also discussed arrangements connected to the Trump administration’s proposed Golden Dome missile-defense system and measures intended to limit Chinese influence on Greenland.
Those details have not all been incorporated into a publicly released final treaty.
The agreement is not yet legally complete
The three governments have announced the framework, but the agreement has not yet entered into force.
Denmark’s prime minister’s office said the pact is expected to be signed during the United Nations General Assembly next week and will then be subject to the necessary national parliamentary procedures.
That leaves important questions unanswered, including the precise rules governing any new U.S. bases, the scope of American access, investment restrictions and the role of Greenlandic and Danish authorities in approving future military infrastructure.
Trump’s description of permanent U.S. security control also goes beyond the limited details publicly released by Denmark and Greenland.
The governments’ statements instead emphasize strengthened cooperation, sovereignty and self-determination.
Greenland remains central to the arrangement
For Greenland, the agreement addresses security without changing its constitutional status.
Nielsen said the pact recognizes Greenland’s interests and its place in international cooperation. That language reflects the island’s long-standing interest in greater self-government and eventual independence while remaining within the existing Kingdom of Denmark.
The agreement therefore separates two issues that had become closely linked during Trump’s campaign for greater U.S. control: Greenland’s sovereignty and the United States’ military interests in the Arctic.
The announced framework preserves the first while expanding cooperation on the second.
Its eventual significance will depend on the final text and how the new military arrangements are implemented after parliamentary approval.
