The Danish defence ministry has instructed its troops to be prepared to “shoot first and ask questions later” if any attempt is made to forcibly seize Greenland, amid renewed threats by US President Donald Trump to take control of the territory, according to local media reports.
Danish soldiers have been authorised to open fire without waiting for direct orders in the event of an invasion attempt, the defence ministry told Berlingske, a Danish newspaper. Greenland is an autonomous territory under Denmark’s jurisdiction and holds strategic importance in the Arctic region.
The directive reportedly stems from a Cold War-era rule dating back to 1952. Under this provision, soldiers are required to “immediately take up the fight” against any foreign force, acting without waiting for or seeking orders—even if commanders are unaware that a state of war has been declared, an Independent report noted.
Roots in World War II history
The rule traces its origins to Denmark’s experience during the Nazi invasion of the 1940s, when German forces swiftly occupied Copenhagen and other cities. The failure to mount an effective military response at the time prompted the adoption of a more decisive doctrine, ensuring immediate resistance to any future foreign aggression. The order has remained in place ever since.
Why Trump wants Greenland
Trump has repeatedly argued that Greenland is critical to US national security, citing its strategic location and increased activity by rival powers in the Arctic.
“We need Greenland from a national security standpoint. It’s very strategic right now,” Trump recently said, claiming the region is frequented by Russian and Chinese vessels.
Despite firm opposition from both Denmark and Greenland’s leadership, Trump has continued to float the idea of US control. When asked whether preserving NATO unity or acquiring Greenland was more important, he told The New York Times: “It may be a choice.” Denmark is a fellow NATO member.
Diplomatic efforts intensify
As rhetoric escalates, senior US officials have begun diplomatic engagements on the issue. According to Reuters, Danish Ambassador Jesper Moller Sorensen and Greenland’s chief representative to Washington, Jacob Isbosethsen, recently met officials at the White House National Security Council. US Secretary of State Marco Rubio is also expected to hold talks with Danish representatives.
Greenland has consistently rejected any suggestion of a takeover. Prime Minister Jens-Frederik Nielsen recently criticised Trump’s remarks, calling comparisons with military interventions elsewhere “disrespectful” and reaffirming Greenland’s stance against any forced acquisition.
