Greenland Parliament Backs U.S.-Denmark Security Pact Expanding Arctic Bases

Greenland's parliament on Tuesday approved a new security pact with Denmark and the United States that clears the way for an expanded American military presence and additional bases on the Arctic island, while affirming it remains under Danish control.^[1]

The Inatsisartut, Greenland's parliament, backed the trilateral agreement in Nuuk by a vote of 16-0, with seven lawmakers abstaining, sending the deal on to Denmark's Folketing for debate and ratification.^[1] The State Department hailed the outcome as "another major victory for American national security," saying the accord will strengthen US defenses and strategic reach in the rapidly changing Arctic region.^[1] The pact is written to continue in force even if Greenland eventually becomes independent, locking in US access regardless of the island's future status.^[1]

The agreement was formally signed in September 2026 on the sidelines of the United Nations General Assembly in New York by President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen, capping months of pressure from Washington to secure broader basing rights.^[1] Existing US facilities in Greenland, most notably Thule Air Base, already give Washington a strategic foothold for missile warning, space surveillance and Arctic air operations, but US officials have argued that ice melt, new shipping lanes and Russia and China's growing polar activity demand a wider footprint.^[1]

Danish and Greenlandic leaders have presented the deal as a way to anchor the island's security within the Western alliance while recognizing its drive for greater self-rule, a balance that has shaped debates since Greenland gained broad home-rule powers from Copenhagen in 2009.^[1] Writing the agreement to survive any future declaration of independence is meant to reassure US planners that access to Arctic infrastructure will not suddenly hinge on a constitutional change in the Danish realm, even as some Greenlandic politicians worry that long-term basing commitments could narrow their foreign policy choices later.^[1]

US officials have framed the vote as a clear signal that Greenland is aligning more closely with Washington at a time of heightened competition with Russia and China, while Danish commentators note that Copenhagen retains ultimate sovereignty and will now have to decide in its own parliamentary debate how far to lean into a more militarized Arctic posture.^[1] For Nuuk, the unanimous yes vote among those backing the pact, alongside a bloc of abstentions, reflects both recognition of the economic and security benefits tied to US investment and unease about the environmental and political impact of more bases on a sparsely populated island already on the front line of climate change.^[1]
