President Donald Trump announced on September 18, 2026, that the United States had reached a deal with Denmark granting Washington control over Greenland's security and establishing a large American military presence on the island.
Greenland is a territory under Danish jurisdiction. Denmark is a NATO ally of the United States, NPR noted.
The Financial Times reported that the agreement hands the US authority over Greenland's security arrangements. Both outlets confirmed that a substantial military buildup is planned there.
The deal comes months after Trump had threatened to take Greenland from Denmark by force, according to NPR. Those threats preceded the agreement by several months.
