Yes — that’s the line President Trump used. On September 18, 2026 he announced a three-party security agreement with Denmark and Greenland and called it “a dream come true for the United States of America.”
The deal is real. The official text has not been released. Signing is expected at the UN General Assembly next week, followed by parliamentary steps in Denmark and Greenland. Characterizations already diverge.
What Trump said
In his Truth Social post he claimed the United States now has:
- “permanent control over security, and all other needs” in Greenland
- an “Infinite Life” agreement with no expiration
- the ability to do whatever is necessary to secure Greenland and the United States
- a prohibition on any U.S. adversary establishing a base, stationing forces, or making “sensitive investments” without express U.S. written approval
- immediate plans to develop “a large Military presence” on the island
- no cost to the United States
He framed it as the first time in more than a century that a president had “permanently and conclusively” addressed Greenland’s strategic importance.
What Denmark and Greenland say
Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen confirmed an agreement is coming. They stress it recognizes the sovereignty and territorial integrity of the Kingdom of Denmark and the Greenlandic people’s right to self-determination. No territory is transferred. The pact is presented as strengthening Arctic and North Atlantic security for NATO.
What officials describe as the substance
U.S. officials (speaking anonymously while the text remains unpublished) and reporting from multiple outlets describe an expansion of the existing 1951 defense arrangement:
- Permanent U.S. basing, access, and overflight rights that would survive even if Greenland later became independent
- Ability to add bases
- Ban on non-NATO military bases or troop presence
- Screening or restrictions on investments by adversaries (aimed at China and Russia) in sensitive sectors such as critical minerals
- Greenland remains part of what Washington calls the strategic defense area of North America
Secretary of State Marco Rubio called it a deal that “permanently and completely addresses our national security concerns in Greenland.”
The existing U.S. presence (Pituffik Space Base and related rights) already had no time limit. The new language is intended to lock in an expanded footprint and explicit adversary exclusions.
Greenland’s ice and fjords remain the geographic prize: the GIUK gap, missile-defense geometry for systems such as Golden Dome, Arctic shipping routes, and mineral resources.
Pituffik Space Base already hosts U.S. radar and space-surveillance assets. The new agreement is designed to let Washington grow that presence.
The gap between “permanent control over security and all other needs” (Trump) and “sovereignty recognized, no land transferred” (Copenhagen and Nuuk) is the story until the actual document is published and ratified. For a news account that wants both the presidential framing and the diplomatic caveats, that tension is the lead.
