In early 2026, Denmark undertook extraordinary covert military measures to defend Greenland against a possible invasion by the United States, amid escalating tensions and explicit threats from former President Donald Trump. Newly revealed details show that Denmark, fearing a US attempt to seize Greenland, deployed troops, explosives, and medical supplies to the Arctic territory, with contingency plans to destroy critical airport infrastructure. These actions, coordinated with European allies under the guise of joint exercises, underscore the region’s heightened strategic significance and the lengths Denmark was prepared to go to protect its sovereignty.

The crisis unfolded in January 2026, when Danish intelligence and government officials became alarmed by renewed US interest in Greenland and aggressive rhetoric from Donald Trump. Denmark’s response was shaped by fears of a sudden US military landing, prompting close coordination with European allies, including France and Sweden, who participated in Arctic security exercises. Danish and Greenlandic officials, as well as local residents, endured a year of anxiety as the threat loomed, though the Danish government and Greenland authorities refrained from public comment.

Denmark discreetly dispatched an army regiment and elite units to Greenland, bringing explosives for the explicit purpose of destroying runways at Nuuk and Kangerlussuaq airports to deny US forces a landing site. Blood bags and other medical resources were also flown in, reflecting preparations for potential casualties. These deployments were conducted under the cover of joint exercises with European allies, masking the true extent of Denmark’s military readiness. Die Welt+2
Danish plans centered on disabling Greenland’s key airfields, particularly at Nuuk and another unspecified location, to prevent any rapid US military incursion. The destruction of runways was seen as a last-resort measure in the event of a US attempt to seize control. These preparations highlight Greenland’s strategic importance and Denmark’s willingness to take drastic action to maintain sovereignty over the territory. The New York Times+2
