The agreement signed by the United States, Denmark and Greenland on 22 September 2026 is a security deal, not a territorial one, and does not end the Arctic contest.

It expands US military access to Greenland while reaffirming Danish sovereignty and Greenland’s right to self-determination.

• Signing: The US, Denmark and Greenland signed the agreement at the UN headquarters on 22 September 2026, ending months of tension over the US wish to gain control of Greenland.
• What the US gets: More military access, including expanding the Pituffik Space Base and new defence areas at Narsarsuaq and Mestersvig, but Greenland stays with Denmark.
• Missile defence and investment: The deal covers the proposed Golden Dome system and limits investment from outside NATO, its partners and the EU.
• Open-ended: It has no end date, and some parts would stay even if Greenland becomes independent.
• It comes into force only after Denmark and Greenland complete their parliamentary approvals.

• It acknowledges the sovereignty and territorial integrity of Denmark and Greenland’s right to self-determination.
• Military access: More US forces, aircraft and ships, including for the defence of Greenland, the NATO area and the American continent.
• Investment curbs: Restrictions on investment from outside NATO in sensitive sectors, to keep rivals out.
• If Greenland becomes independent: The Danish and Greenland governments must ensure the new state stays in NATO and takes on the rights and duties under the agreement.

• Location: It lies between North America and Europe, which matters for missile warning, space surveillance and the security of the North Atlantic.
• Arctic routes and resources: New sea routes and critical minerals are opening as ice melts.
• Rivals: Russia’s military presence and China’s economic and scientific interests have changed the strategic setting.

• Self-determination: A broad military access and investment curbs limit what Greenland can decide for itself.
• Open-ended terms: The agreement has no end date and can be changed only by mutual consent.
• Allied friction: Competition in the Arctic can also create tensions among allies.
• Denmark’s balance: It had to protect its sovereignty without a long clash with Washington.

• Arctic stake: India is an observer in the Arctic Council (since 2013), and its Arctic Policy (March 2022) covers science, shipping and minerals.
• Research: Himadri, India’s station at Ny-Ålesund, Svalbard, studies links between the Arctic and the Indian monsoon.
• Risk: A militarised Arctic can shrink room for science-based cooperation and raise tension on routes and resources.

• Greenland: An autonomous territory within the Kingdom of Denmark. Under the 2009 Self-Government Act, it controls most domestic affairs, while foreign, defence and security policy stay with Denmark.
• Earlier agreement: The 1951 defence agreement, which the 2026 deal amends.
• Golden Dome: A proposed US air and missile defence system.
• Arctic Council: Set up by the Ottawa Declaration, 1996, with eight members: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the US. Its secretariat is in Tromsø, Norway.
• India and the Arctic: Himadri station (2008), observer status (2013), Arctic Policy (17 March 2022).
