Denmark’s prime minister used her annual New Year’s address to deliver a blunt and highly symbolic rebuke to Donald Trump, warning that her country will “stand firm” against his renewed push to take over Greenland and signaling that Denmark is rapidly strengthening its military posture in response.

In a televised speech Thursday evening, Mette Frederiksen told viewers that Denmark is moving at an unprecedented pace to bolster its defenses, particularly in the Arctic, as pressure mounts from its longtime ally. She framed Trump’s campaign to annex Greenland as a fundamental challenge not only to Danish sovereignty, but to the international rules that govern relations between nations.

“Never before have we increased our military strength so significantly, so quickly,” Frederiksen said, according to Denmark’s Berlingske newspaper. She described a year marked by threats, pressure, and hostile rhetoric coming from “our closest ally for a lifetime,” and rejected the idea that another country and its people could simply be taken over “as if it was something you could buy and own.”

Frederiksen emphasized that Denmark is not seeking conflict, but made clear that it would not bend. Her remarks were echoed hours later by King Frederik X, who used his own New Year’s Eve address to highlight expanded military training programs and to praise Greenlanders’ “strength and pride” during what he called a turbulent period.

The unusually unified messaging from Denmark’s political and royal leadership comes as Trump has escalated his rhetoric since returning to office in 2025. He has repeatedly insisted that the United States needs Greenland for national security and has even floated the possibility of using military force to make it happen.

Tensions spiked again last week when Trump appointed Jeff Landry as a special envoy tasked with advancing U.S. interests in Greenland, an autonomous territory within the Kingdom of Denmark. The appointment was widely interpreted in Copenhagen as a direct provocation.

Speaking at a December 23 press conference, Trump brushed aside Denmark’s historical ties to the island and doubled down on his claim. “We need it for national protection,” he said, suggesting Greenland’s status was negotiable despite centuries of Danish governance.

Public opinion on the island itself tells a very different story. Polls consistently show that Greenlanders overwhelmingly oppose becoming part of the United States, a reality Danish officials frequently cite when rejecting Trump’s assertions.

The dispute has already altered Denmark’s national security outlook. Earlier this month, Denmark’s intelligence service took the unprecedented step of identifying the United States as a potential security threat, citing Washington’s growing willingness to use economic and military power to “enforce its will… even against allies.” It marked the first time the U.S. has been described in such terms by Danish intelligence.

Even as political tensions rise, U.S. activity in Greenland continues. The American consulate in Nuuk, Greenland’s capital, is still recruiting unpaid interns to help advance U.S. foreign policy messaging on the island. According to a job listing first posted in 2023 and highlighted by European outlet Euractiv, interns would assist in communicating American priorities to Greenlandic audiences.

While unpaid internships are common in Denmark, they are typically supported by generous student subsidies, meaning local taxpayers could indirectly fund efforts tied to Trump’s annexation agenda — a detail that has further irritated Danish officials.
