The US, Denmark, and Greenland announced on Sept. 18, 2026 an agreement for Washington to develop a "significant military presence" on Greenland while prohibiting adversary bases or sensitive investments without US written approval
Trump posted on Truth Social that the deal gives the US "permanent control" over Greenland's security and "all other needs" — language that directly contradicts Danish and Greenlandic insistence that sovereignty remains intact
Denmark's Foreign Minister Lars Lokke Rasmussen said the deal would respect the Kingdom's "red lines" and could "strengthen security in the Arctic and the North Atlantic" while ending months of uncertainty triggered by Trump's earlier threats to seize Greenland
Greenland's Prime Minister Jens-Frederik Nielsen said the proposed deal "recognises the sovereignty and territorial integrity of our Kingdom and the right of the Greenlandic people to self-determination"
Key details of the agreement remain undisclosed, including the scale of the US military presence and whether any formal authority over foreign policy or resources would be ceded to Washington; the deal is expected to be signed during the UN General Assembly next week
Residents in Nuuk voiced skepticism about closer US ties, with a 65-year-old saying the US "should not control Greenland" and a 71-year-old retired chef telling Reuters: "He should not expect our children and grandchildren to become Americans in the future"
NATO welcomed the agreement as advancing "security, stability and cooperation in this vital region," while a University of Copenhagen professor warned that any ceding of formal authority could "replace the colonial relationship with Denmark with a colonial relationship to the United States"

Why it matters: The deal's secrecy is the central fault line: Trump publicly frames it as giving the US "permanent control" while Denmark and Greenland insist sovereignty is preserved. University of Copenhagen professor Mikkel Vedby Rasmussen warned that if Copenhagen cedes any formal authority, Greenlanders could end up swapping one colonial power for another — a concern Nuuk residents echoed on the record.
