Examine the tension between sovereignty, self-determination and alliance security in the case of Greenland.

Greenland is an autonomous part of the Kingdom of Denmark. Under the Self-Government Act, 2009, foreign and defence policy stay with Copenhagen [3]. On 22 September 2026, the US, Denmark and Greenland signed an Arctic security agreement at the UN, replacing Washington's acquisition push with wider military access [1]. The deal manages a three-way tension but does not resolve it.

Sovereignty vs Alliance Security

• The agreement reaffirms Danish sovereignty and territorial integrity. Yet US aircraft may fly over and land anywhere in Greenland, and US vessels get undersea access to its territorial waters [2].
• The US may expand Pituffik Space Base and set up a Defense Area at Narsarsuaq and Mestersvig [2]. Formal title stays Danish, but operational control shifts towards Washington.
• Non-NATO states are barred from military installations, and outside investors are screened in sensitive sectors, including resource extraction [2]. Alliance security narrows Greenland's economic choices.

Self-Determination vs Alliance Security

• Greenlanders are recognised as a people with the right to self-determination. Independence remains possible under Article 21 of the 2009 Act [2][3].
• However, the deal has no end date. A future independent Greenland must remain in NATO and take over Denmark's obligations [2], so its strategic choices are fixed before independence.
• History advises caution. The 1951 base deal had no Greenlandic voice. Inughuit families were relocated for the base's expansion in 1953, and the Hingitaq 53 group won its case only in the late 1990s [4].

Sovereignty vs Self-Determination (Copenhagen–Nuuk)

• Gains: Greenland signed as a party, and the deal enters into force only after parliamentary procedures in Denmark and Greenland [1][2].
• Limits: After ratification, defence stays Danish [3]. Consultation runs between governments through a Permanent Committee, and the deal sets no explicit duty to consult local communities [2]. Contracts go to Greenlandic sources only "to the maximum extent possible" [2], which means benefits rather than control.

Way Forward

• Require free, prior and informed consent of communities near new defence sites.
• Give Nuuk a formal role in Permanent Committee decisions, and hold periodic joint reviews.
• Link basing to measurable local economic and environmental safeguards.

Overall, Greenland shows how alliance security can coexist with sovereignty in law while straining it in practice. Turning coercion into a treaty that parliaments must ratify is real progress over 1951. Lasting Arctic stability will depend on giving self-determination, a principle of the UN Charter (Article 1(2)), real substance through continuing consent rather than one-time ratification.
