President Donald Trump announced on September 18, 2026, that the United States and Denmark had reached an agreement giving Washington permanent control over security matters in Greenland, the autonomous Danish territory he has repeatedly sought to bring under American influence. Trump said the deal addresses all US security concerns on the Arctic island at no cost to the United States and described it as an arrangement meant to last indefinitely.
Under the terms outlined by both governments, Denmark retains sovereignty over Greenland and the territory's right to self-determination is preserved. The agreement reportedly grants the United States access, basing, and overflight rights, while barring rival powers from establishing a military presence or making sensitive investments there without American approval. Trump said the US intends to begin building a substantial military presence on the island.
The agreement is expected to be formally signed during the United Nations General Assembly session in New York next week, according to Danish officials, though it still requires approval from the Danish parliament before taking full effect. The deal follows more than a year of tension after Trump repeatedly floated the idea of the United States acquiring Greenland by force or purchase, alarming officials in Copenhagen and among NATO allies.
