United States, Denmark, and Greenland reach Arctic security agreement

The US, Denmark, and Greenland have reached a security deal, with Trump claiming permanent control while Nordic officials emphasize NATO ties and sovereignty.
United States President Donald Trump announced a defense agreement with Denmark and Greenland, claiming on Truth Social that it grants permanent American authority over Greenland's security. Trump stated the arrangement provides indefinite authorization for defense measures and prevents rival foreign nations from establishing military installations on the island.
Danish authorities confirmed the agreement, which will be signed at the United Nations General Assembly. Nordic media emphasized contrasting perspectives on the deal. While Trump presented the outcome as a major victory, European diplomats stressed that the pact respects Danish sovereignty and strengthens NATO security, having successfully framed the arrangement to satisfy American political demands.
