In a region where melting ice is redrawing the map of human ambition, the United States, Denmark, and Greenland have formalized a trilateral security pact — transforming months of diplomatic friction into a shared framework for Arctic stewardship. Signed by President Trump on Tuesday, the accord acknowledges that Greenland's geographic and resource significance cannot be managed unilaterally, and that great-power competition in the far north demands coordinated response. It is, at its core, a recognition that sovereignty and security are not always rivals — sometimes they must be partners.
