Denmark says Greenland’s sovereignty will remain intact under a proposed security agreement with the United States that would allow Washington to significantly expand its military presence on the strategically important Arctic island.
The United States, Denmark and Greenland announced Friday that they had reached an agreement aimed at strengthening U.S. security capabilities in Greenland while preventing countries such as Russia and China from establishing military bases or other strategic footholds there.
U.S. President Donald Trump described the arrangement as giving the United States “permanent control” over Greenland’s security. However, Danish and Greenlandic officials have emphasized that the agreement does not transfer sovereignty over the territory to Washington.
Danish Foreign Minister Lars Løkke Rasmussen said the proposed agreement should strengthen security in the Arctic and North Atlantic while respecting Denmark’s sovereignty and the government’s stated red lines. Greenland’s Prime Minister Jens-Frederik Nielsen also 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.
The precise terms of the agreement have not yet been made public. Important questions remain over the scale of the planned U.S. military presence and whether Washington would receive any additional authority relating to Greenland’s foreign policy, natural resources or security decisions.
Under Trump’s description, the agreement would prevent U.S. adversaries from establishing military bases or maintaining a military presence in Greenland. It would also restrict sensitive investments by those countries unless Washington gives written approval. U.S. officials have said the arrangement is intended to prevent potential Chinese or Russian military and economic influence in the Arctic territory.
Greenland’s strategic location makes it important to North American and European defence. The island sits between North America and Europe and is home to the U.S. Space Force’s Pituffik Space Base, which supports missile warning, space surveillance and other defence activities.
The proposed agreement follows months of diplomatic tension after Trump repeatedly said the United States needed control of Greenland for national security reasons. His earlier comments about potentially acquiring the territory created concern in Denmark and Greenland and contributed to tensions within NATO.
Denmark and Greenland have consistently maintained that Greenland is not for sale and that decisions about its future must respect the wishes of its people. The new agreement appears intended to address U.S. security concerns while maintaining the existing constitutional relationship between Greenland and Denmark.
NATO has welcomed the agreement, saying it could help strengthen security, stability and cooperation in the Arctic and North Atlantic region. The development comes as NATO members increasingly focus on Arctic security amid growing strategic competition in the region.
The agreement is expected to be signed during the United Nations General Assembly in New York next week. Parliamentary action in Denmark and Greenland is still required before the arrangement can be implemented.
For Greenland, the issue remains particularly sensitive because the territory has its own government and has a recognized right to self-determination. While the proposed agreement could result in a greater U.S. military role, Danish and Greenlandic leaders say that does not amount to a transfer of sovereignty.
The final impact of the deal will depend on its detailed provisions and the legal process that follows. Until the full text is released and approved, the exact extent of the United States’ additional security responsibilities in Greenland remains unclear.
