A trilateral agreement due Tuesday at the U.N. will let the U.S. reopen the former Bluie West One site at Narsarsuaq and establish a presence at Mestersvig on Greenland’s east coast.
The deal would expand the U.S. footprint beyond Pituffik Space Base, where about 150 American personnel remain, after Greenland once hosted 17 U.S. installations and more than 10,000 troops during the Cold War.
Denmark has framed the arrangement as placing Arctic security under NATO oversight rather than leaving it solely to Washington and Copenhagen, though the text was still not public before signing.
The accord follows months of pressure from Donald Trump, whose push for U.S. control of Greenland and refusal to rule out force triggered a NATO diplomatic crisis and negotiations with Denmark and Greenland.
