US and Denmark Reach Deal on Greenland Security

The United States and Denmark reached an agreement on Greenland's security, according to statements from President Trump on September 18, 2026. Trump said the deal gives the US a permanent role in Greenland's security and expands the American military presence on the island. He described the arrangement as "infinite" and said no adversary would be able to establish a base there.

The agreement stops short of a US takeover of Greenland, which Trump had previously discussed. Details of the deal have not been fully released.
