So far, the deployment remains intergovernmental and has not been formally approved by NATO, according to two people familiar with the matter.

“The goal is to show that Denmark and key allies can increase their presence in the Arctic region,” said a third person briefed on the plans, demonstrating their “ability to operate under the unique Arctic conditions and thereby strengthen the alliance’s footprint in the Arctic, benefiting both European and transatlantic security.”

The announcement landed the same day U.S. Vice President JD Vance and Secretary of State Marco Rubio met with the Danish and Greenlandic foreign ministers in Washington, following days of rising transatlantic tensions over President Donald Trump’s bid to take over the strategic island.

Trump escalated the dispute earlier Wednesday in a Truth Social post, declaring that “the United States needs Greenland for the purpose of National Security,” calling it “vital” for his planned “Golden Dome” missile defense system. 

He also insisted that seizing Greenland would not destroy NATO, despite warnings from Danish Prime Minister Mette Frederiksen that such a move would end the Atlantic alliance.

“Militarily, without the vast power of the United States … NATO would not be an effective force or deterrent — Not even close!” Trump posted. “They know that, and so do I. NATO becomes far more formidable and effective with Greenland in the hands of the UNITED STATES.”
