US, Denmark and Greenland Ink Deal to Boost Military Presence While Preserving Danish Sovereignty

The United States, Denmark and Greenland signed a security agreement on September 22, 2026 at the United Nations. The pact expands the U.S. military footprint in Greenland while confirming Denmark's sovereignty over the island and Greenland's right to self‑determination. Under the 2009 Self‑Government Act, Greenland controls domestic matters but Denmark retains foreign, defence and security authority. The new deal therefore adds U.S. forces under Danish oversight rather than shifting control to Washington. The agreement is intended to ease the recent friction between Washington and Copenhagen that grew after the Trump administration repeatedly pressed for greater U.S. control of the territory. The deal will come into force only after the required parliamentary approvals in both Denmark and Greenland are completed. Analysts say the balance struck by the three parties will shape Greenland's future as climate change opens new Arctic routes and resource opportunities. The United Nations setting underscored the global interest in Arctic stability. Critics in Greenland worry that increased U.S. presence could limit the island's autonomy, while Danish officials stress that the pact safeguards both security and self‑governance.
