US-Greenland security pact expands U.S. military footprint in the Arctic

The U.S., Denmark and Greenland signed a security agreement giving the United States broad access to Greenland's airspace and territory, expanding the Pituffik Space Base and allowing two additional bases at Narsarsuaq and Mestersvig, with the option to add more defense areas; the pact has no expiration and tightens screening of non-NATO investments to curb China and Russia, reflecting a changing Arctic security landscape while Greenland remains within the Kingdom of Denmark.
