Trump administration secures expanded security agreement on Greenland

The United States and Denmark agreed on a new security deal for Greenland in September 2026. President Trump said the agreement gives the US permanent control over security in the territory. The deal bans military bases from countries outside NATO. It also stops China and Russia from building a military presence or investing in sensitive areas without US approval. Danish Prime Minister Mette Frederiksen said three governments would sign the deal the following week. The US has had a security agreement with Greenland since 1951, but the exact changes from that older deal are not yet clear. Secretary of State Marco Rubio called it a historic agreement. Trump had previously threatened to take Greenland by force before choosing to negotiate instead.
