U.S., Denmark and Greenland sign Arctic security pact authorising new bases
At a United Nations session the United States, Denmark and Greenland concluded a security agreement that permits the construction of U.S. defence installations at Narsarsuaq in the south and Mestersvig on the east coast, as well as an upgrade of the existing Pituffik Space Base. The pact affirms Denmark’s sovereignty and bars non‑NATO states from establishing similar sites, while stating that the provisions would remain in force even if Greenland were to separate from Denmark.
President Donald Trump, who first raised the idea of a greater U.S. presence in Greenland in 2019, described the deal as a partisan flashpoint but essential for countering Russian activity in the Arctic. Greenlandic Prime Minister Jens‑Frederik Nielsen and Danish officials presented the agreement as a step toward greater Greenlandic involvement in its own security decisions.
