The US, Denmark and Greenland have signed a trilateral Arctic security deal on the UNGA sidelines, granting Washington two new military bases in Greenland.
- The agreement allows the US to build two new military bases at Narsarsuaq and Mestersvig, and to modernise and expand operations at its Pituffik Space Base.
- No non-NATO country may establish military installations or a persistent military presence in Greenland without the three parties' unanimous approval.
- Trump announced the US would immediately begin developing a large military presence in Greenland, including two major bases.
- The agreement has no end date, and Greenland would remain in NATO and assume Denmark's obligations if it becomes independent.
- Mette Frederiksen and Jens Frederik Nielsen welcomed the deal, but Trump did not retract his earlier threats to annex Greenland.
- The agreement restricts sensitive investments in Greenland to the US and its allies, ending the previous status quo that permitted adversaries to invest without scrutiny.
- The agreement affirms Danish sovereignty over Greenland and the right of Greenlanders to self-determination.
