"Great-power coercion of allies erodes the rules-based order." Discuss with reference to the U.S.–Greenland episode.

On 22 September 2026, the U.S., Denmark and Greenland signed an agreement amending the 1951 U.S.–Denmark defence pact, permitting new American defence areas at Narsarsuaq and Mestersvig and expansion of Pituffik Space Base [1]. Reached after months of presidential demands to acquire the island — including a refusal to rule out force — the episode shows how coercion of an ally corrodes rules even when no shot is fired.

How the episode eroded the rules-based order

• Threat itself is the breach: Article 2(4) of the UN Charter obliges members to refrain from "the threat or use of force against the territorial integrity or political independence of any state" [2]. The violation occurred at the moment of threat; a later friendly deal does not cure it.
• Alliance norms strained: coercion was directed at Denmark, a NATO founding member, converting an Article 5 partnership into a bargaining relationship.
• Consent deficit: though Greenland signed, defence and foreign affairs remain Danish competences under the 2009 Act on Greenland Self-Government [3], so the party most affected could not legally refuse.
• Precedent: coercion that yields expanded basing rights teaches revisionist powers that territorial pressure pays.

The other side

• The outcome stayed within existing law — an amendment to the 1951 treaty, not a transfer of sovereignty [1].
• A genuine capability gap existed: Arctic melting has reopened sea routes and missile-warning geographies, and Pituffik alone is thin cover.
• Yet permission was never lacking; the 1951 pact already allowed bases [1]. Concede the security need, reject the method.

Relevance for India India, an Arctic Council Observer, engages the region through the Arctic Policy, 2022 — India and the Arctic: building a partnership for sustainable development [4], whose governance-and-cooperation pillar presumes a low-tension Arctic.

The episode ends in a treaty, but the path there weakened the norm against coercion — the same norm India invokes against unilateral border change. The durable remedy is to route Arctic questions back through multilateral forums and to make consent of affected populations integral to basing arrangements, so that security guarantees strengthen sovereignty rather than substitute for it.
