US and Denmark reach Greenland security deal, ending Trump annexation threats

After months of threats to seize Greenland by force, President Donald Trump announced a security agreement with Denmark that he says resolves the dispute without military action. The deal, which will be signed at the United Nations General Assembly the following week, grants the United States what Trump described as "permanent control over security, and all other needs" in the Arctic territory. He claimed it came at no cost to America and would allow the US to "do what is necessary" to protect Greenland's security.

The specifics of what Trump claimed the agreement contains have not been confirmed by Danish officials. According to an unnamed US State Department official, the deal includes provisions allowing the US to build additional military structures unilaterally, without approval from either Greenland or Denmark. It grants permanent access, basing, and overflight rights. The agreement also prohibits non-NATO countries from establishing military bases in Greenland and bars what the official called "adversaries"—specifically naming Russia and China—from making investments in sensitive sectors that could threaten American interests. Under the current arrangement, the official said, such investments had been permitted without screening.

Denmark's Prime Minister Mette Frederiksen framed the agreement differently, emphasizing that it "strengthens our common security in the Arctic and the North Atlantic area" while simultaneously recognizing "the sovereignty and territorial integrity of the Kingdom and the right of the Greenlandic people to self-determination." She noted that the deal would need to pass through parliamentary procedures before taking effect. Jens-Frederik Nielsen, chairman of the Greenland Government, called it gratifying that an agreement was being reached, saying it "ensures and strengthens the security" of all three parties and recognizes Greenland's interests in international cooperation.

Trump's interest in Greenland had intensified over several months, driven by what he characterized as national security concerns about the territory's strategic location for defense purposes and its vast reserves of rare earth minerals—many essential for mobile phones and electric vehicles. He had proposed purchasing the territory outright and at one point suggested military action, prompting strong reactions from Denmark and other NATO allies. The president has stated that Greenland is central to his plan for a "Golden Dome" defense system intended to protect the US against missile attacks from Russia and China, with potential involvement from European allies.

One notable aspect of the agreement, according to the State Department official, is that it remains in force even if Greenland becomes an independent nation in the future. The US already maintains a permanent military presence in Greenland, with more than 100 personnel stationed at Pituffik base in the northwestern part of the territory. However, no text of the agreement has been released publicly, making it difficult to assess how substantially it differs from a 1951 agreement between the US and Denmark that already permits the US to deploy as many troops as needed to Greenland.

US Secretary of State Marco Rubio called the deal a "historic" achievement and "a huge win for the United States and the American people," stating that it "permanently and completely addresses our national security concerns in Greenland." The agreement now awaits parliamentary approval in Denmark before formally entering into force, leaving open questions about what specific new authorities or restrictions the deal actually establishes beyond existing arrangements.
