After months of threats to acquire Greenland, President Trump announced a deal Friday expanding the U.S. security presence in the semiautonomous Danish territory. The agreement falls short of the outright takeover Mr. Trump demanded, which had roiled NATO. In a social media post, Mr. Trump claimed the deal gives the United States "permanent control over security, and all other needs" in Greenland, including veto power over foreign military bases and sensitive investments. However, Danish Prime Minister Mette Frederiksen emphasized the agreement "recognizes the sovereignty and territorial integrity" of Denmark.

Negotiators from the United States, Greenland, and Denmark met in Washington for high-stakes talks. Mr. Trump said the pact ensures no U.S. adversary can establish a base or military presence in Greenland without American approval, calling it an "Infinite Life Agreement." Ms. Frederiksen said the deal strengthens common security in the Arctic and North Atlantic, benefiting NATO and Europe.

Mr. Trump has long argued Greenland is vital for U.S. national security and global protection, citing the strategic naval corridor between the Atlantic and Arctic. He warned that if the U.S. did not act, Russia or China would take over. The region is increasingly contested due to melting ice, undersea cables, and vast rare-earth mineral deposits essential for batteries and electric vehicles. Polls show a vast majority of Greenlanders oppose joining the United States.
