Yes. On September 18, 2026, President Donald Trump said the United States had entered into an agreement with Denmark and Greenland that gives the U.S. permanent control over security — and, in his words, “all other needs” — in Greenland. Reuters reported the announcement the same day.
Danish Prime Minister Mette Frederiksen said the three parties expect to sign a deal strengthening Arctic and North Atlantic security on the sidelines of the U.N. General Assembly the following week, while recognizing Danish sovereignty and Greenlanders’ right to self-determination. She also said the pact still needs parliamentary procedures before it can enter into force. No full public text of the agreement had been released at the time of Trump’s announcement.
