Where it stands

The United States, Denmark and Greenland signed a defence agreement in New York on 22 September 2026. It would expand American military access in Greenland while reaffirming the Kingdom of Denmark's sovereignty and Greenlanders' right to self-determination. Greenland is not being transferred to the United States. The agreement still requires the necessary parliamentary procedures before it enters into force. The United States already has a military presence under earlier defence arrangements. The new text permits modernisation and expansion at Pituffik Space Base and provides for additional defence areas at Narsarsuaq and Mestersvig. Their technical arrangements must be agreed by the parties. Further defence areas would also involve proposals and consultations, not an unrestricted American decision to occupy any location. For Greenland, the agreement combines potential security and local-contracting benefits with longer-term commitments concerning military access and sensitive investment. It also says a future independent Greenland must assume the defence obligations and remain within NATO through the specified process. The pact therefore preserves sovereignty while placing important conditions on how future security arrangements would continue. Signing those commitments is different from building new bases or completing every legal step needed to implement them.

Background

Greenland lies between North America and the European Arctic, making it important to North Atlantic defence. Military facilities there can support surveillance and the movement of forces across the region. The United States has operated under a defence relationship with Denmark dating to 1951. Later agreements adjusted that relationship and included Greenland's government. Military access and sovereignty answer different questions. Access determines what a foreign military may do under an agreement, such as operating a base or moving aircraft. Sovereignty concerns the authority over the territory itself. A country can permit a foreign base without transferring ownership or becoming part of that foreign country. That distinction matters because Donald Trump had repeatedly called for the United States to acquire Greenland. The signed text instead reaffirms Danish sovereignty and the Greenlandic people's right to determine their political future. It expands the security arrangement within that stated framework. The relevant comparison is therefore between earlier and expanded defence permissions, not between Danish and American ownership. The remaining legal and practical steps also matter. Parliamentary procedures must be completed before the agreement becomes operative. Individual defence projects require the consultations or technical arrangements specified in the text. Greenlandic communities and businesses may be affected by where installations are placed, how contracts are awarded and how local activities are protected.

22 September 2026; agreement signed in New York

How it started
Expanded defence permissions still require legal and practical follow-through

The text provides for expanding activities at Pituffik and establishing additional defence areas at Narsarsuaq and Mestersvig. Implementation details at the new sites must be mutually agreed. Proposals for further defence areas go through consultation, with escalation to senior officials if agreement is not reached within 90 days. The agreement also provides wider movement and access rights for American forces, aircraft and public vessels. It requires respect for Greenlandic society and traditional activities to the maximum extent possible. Contracts connected with defence areas should go to Greenlandic suppliers where their capabilities and feasibility permit. These provisions create opportunities and obligations; they do not guarantee that every contract will be local. Sensitive investment is another part of the pact. It restricts certain security-threatening involvement by investors outside NATO, NATO partner countries and EU member states, subject to an agreed exception. This is not a blanket ban on every foreign investment. The parties also make commitments concerning continuity of the defence arrangements if Greenland later becomes independent. The agreement has no stated end date and can be amended by mutual consent. It enters into force through a diplomatic notification after the necessary parliamentary procedures. Signing alone does not bring the expanded permissions into force.

Why it matters for UPSC

GS2 · International agreements and sovereigntyGS1 · Arctic geographyGS3 · Security

For GS2, distinguish sovereignty, military access, self-determination and entry into force of an agreement. Link Arctic geography with NATO and North Atlantic security. Examine how a treaty can preserve territorial sovereignty while creating extensive and lasting defence obligations.

Key terms

SovereigntyThe authority of a state over its territory and affairs. The agreement reaffirms the Kingdom of Denmark's sovereignty. Permission for another country's military to use facilities does not, by itself, transfer the territory to that country.

Self-determinationA people's right to determine their political status. The agreement recognises this right for Greenlanders while making specific commitments about defence arrangements if independence occurs. Recognition of the right does not mean independence has already taken place.

NATOThe North Atlantic Treaty Organization, a military alliance based on cooperation in collective defence. Greenland is covered through the Kingdom of Denmark. The new agreement supports a stronger allied role in Arctic planning, exercises, presence and intelligence gathering.

Defence areaAn area in Greenland where the United States establishes or operates a military base under the defence arrangements. A proposal identifies its location, scope and activities. The agreement sets procedures for implementation rather than treating every place as an existing American base.

Entry into forceThe point at which an agreement becomes legally operative under its terms. Here, that follows a diplomatic notification that the necessary parliamentary procedures are complete. Signing the document and bringing it into force are separate steps.

Investment screeningExamination of investment for risks such as threats to national security or public order. The pact addresses specified involvement in particularly sensitive sectors, including infrastructure and resource extraction. It does not simply prohibit all foreign businesses from operating in Greenland.

Permanent CommitteeThe consultation body used for matters concerning the American military presence in Greenland. Under the new text, it helps determine implementation details for proposed defence areas. Unresolved consultations can be escalated to higher political levels.

Pituffik Space BaseThe existing American military base in Greenland identified in the agreement for modernisation and expanded activities. It is different from the additional defence areas envisaged at Narsarsuaq and Mestersvig. The pact does not mean all three locations have newly completed bases.
