Denmark Warns U.S. Against Greenland Takeover as Trump Revives Annexation Threats.
Denmark has issued its starkest warning yet to Washington, cautioning that any U.S. attempt to seize Greenland by force would shatter eight decades of transatlantic security and effectively end NATO as it exists today.
The warning comes as President Donald Trump doubles down on his long-standing fixation with Greenland, arguing the Arctic territory is vital to U.S. national security and hinting — again — that Denmark cannot be trusted to manage it. His comments have reignited European alarm, coming just days after Washington’s unprecedented military operation in Venezuela.
“If the United States decides to militarily attack another NATO country, then everything stops,” Danish Prime Minister Mette Frederiksen said bluntly. “That includes NATO and the entire post-World War II security order.”
Greenland, an autonomous territory within the Kingdom of Denmark, occupies one of the most strategic positions on Earth — sitting on the shortest missile path between Russia and the U.S., rich in untapped rare earth minerals, and home to America’s northernmost military base. But Copenhagen and Nuuk insist strategic cooperation does not equal sovereignty transfer.
Greenland’s Prime Minister Jens-Frederik Nielsen told Trump to “back off,” rejecting what he called fantasies of annexation. “No more pressure. No more insinuations,” he said, while stressing that any dialogue must respect international law.
European leaders moved quickly to close ranks. The European Union reaffirmed its commitment to Denmark’s territorial integrity, while Britain, France, and the Nordic states echoed a clear message: borders cannot be changed by force — even by allies.
The crisis escalated after a pro-Trump figure posted an image of Greenland draped in the U.S. flag with the caption “SOON,” prompting outrage in Copenhagen and Nuuk. Danish officials labeled the message “disrespectful” and dangerous, especially at a moment when Trump openly boasts about reshaping global order through force.
China, meanwhile, rejected Trump’s claims that Beijing poses a military threat in Greenland, accusing Washington of inventing excuses for territorial ambition.
For Denmark and much of Europe, the lesson from Venezuela is clear: Trump’s rhetoric is no longer theoretical. Greenland, once a geopolitical footnote, has become the next red line — and crossing it could fracture the Western alliance itself.
