Trump says US reached Greenland security deal
Tap title to read story
United States President Donald Trump announced an agreement with Denmark and Greenland establishing permanent U.S. security control over the Arctic territory. Published on Truth Social, Trump described the arrangement as an infinite life pact carrying zero financial cost to Washington. Under stated terms, adversarial nations face prohibitions on military bases or sensitive investments without express U.S. written approval. Washington intends immediate military expansion collaborating with local inhabitants.
Danish Prime Minister Mette Frederiksen and Greenlandic officials indicated potential formal signing next week during the United Nations General Assembly. European statements emphasize respect for Danish sovereignty and Greenlandic self-determination, framing the understanding around standard Western security cooperation rather than territorial annexation.
The announcement follows prior diplomatic tensions involving U.S. acquisition proposals and European tariff threats earlier in 2026. Existing U.S. defense operations operate via the Pituffik Space Base under legacy treaties. Final legal parameters, deployment coordinates, and ratification texts remain pending official diplomatic execution next week.
