Trump, Denmark and Greenland Set to Sign Arctic Security Deal Amid Greenland Standoff
US President Donald Trump is set to sign a new security agreement with Denmark and Greenland at the UN General Assembly in New York, paving the way for an expanded US military presence on the strategically important Arctic island. Denmark says the arrangement will place Arctic security within NATO’s broader framework while preserving its sovereignty and Greenland’s right to self-determination.

Trump, Denmark and Greenland Set to Sign Arctic Security Deal Amid Greenland Standoff
US President Donald Trump is due to meet Danish Prime Minister Mette Frederiksen and Greenland Prime Minister Jens-Frederik Nielsen in New York on Tuesday to sign a trilateral agreement aimed at easing months of tension over Greenland.
The agreement is expected to expand the US military footprint on the mineral-rich Arctic island, with two additional sites planned alongside the existing Pituffik Space Base. Reuters reported that the proposed locations are Narsarsuaq in southern Greenland and Mestersvig on the east coast.
Narsarsuaq was formerly home to the US Cold War-era Bluie West One airbase, which was closed in the 1950s. Mestersvig is currently used by Denmark's Sirius Dog Sled Patrol, a special forces unit.
NATO role in Arctic security
Danish Foreign Minister Lars Lokke Rasmussen has said the agreement will put Arctic security under NATO's collective responsibility rather than leaving it solely to the United States and Denmark. The arrangement follows months of diplomatic tension after Trump repeatedly pushed for greater US control over Greenland.
Trump has described the agreement more broadly, saying it gives the United States “permanent control” over Greenland's security. Denmark, however, has not endorsed that interpretation and has stressed that the deal respects the sovereignty of the Kingdom of Denmark and Greenland's right to self-determination.
Agreement details remain unpublished
The full text of the agreement had not been released before Tuesday's signing, leaving questions about its precise legal structure and whether it will modify the existing 1951 defence arrangement governing the US military presence in Greenland.
Greenland's strategic position between North America and the Arctic has made the territory increasingly important to US and NATO security planning. During the Cold War, the United States maintained 17 military installations and more than 10,000 personnel on the island. Today, the Pituffik Space Base is the only active US military installation there.
The new agreement represents a shift from Trump's earlier calls for US acquisition of Greenland toward a framework focused on expanded military access and Arctic security. Its final implications will depend on the text signed by the three governments and how the new security arrangements are implemented.
