Denmark’s defense ministry has confirmed that a 1952 military directive requiring soldiers to respond instantly to any invading forces—without waiting for orders—remains active . This policy, which effectively instructs troops to “shoot first and ask questions later,” applies to the defense of Greenland, a Danish overseas territory, amid renewed statements from US President Donald Trump about potentially acquiring the island, including through military means.

The 1952 Directive

The rule, established in 1952, mandates that in the event of an invasion, “the attacked forces must immediately take up the fight without waiting for or seeking orders, even if the commanders in question are not aware of the declaration of war or state of war.” It is designed to ensure a rapid defensive response to any aggressor.

On January 7, 2026, Denmark’s defense ministry, led by Minister Troels Lund Poulsen, reaffirmed the directive’s status when questioned by the Danish newspaper Berlingske. The ministry stated: “The order on precautionary measures for military defence in the event of attacks on the country and during war, remains in force.”

Renewed US Interest in Greenland

The confirmation follows recent remarks by President Trump, who has reiterated his view that the United States needs control of Greenland for national security reasons, citing threats from Russia and China in the Arctic. Trump has not ruled out military action, with White House statements indicating that using US forces is “always an option” among discussions on acquiring the territory.

Denmark has consistently maintained that Greenland is “not for sale,” and Greenland’s government has rejected any transfer of control. Danish Prime Minister Mette Frederiksen has warned that a US attack on the NATO territory would mark the end of the alliance and postwar security structures.

International and Diplomatic Responses

European leaders, including those from the UK, France, Germany, Italy, Spain, and Poland, have issued joint statements supporting Denmark and affirming that Greenland’s future is for its people and Denmark to decide . Urgent consultations are underway among European nations, with Germany coordinating closely with Denmark on potential next steps.

US Secretary of State Marco Rubio announced plans to meet with Danish and Greenlandic officials the following week to discuss the issue . Rubio has indicated that the administration prefers diplomatic solutions, such as purchasing the island, and has briefed US lawmakers that threats do not signal an imminent invasion.

Former French Prime Minister Dominique de Villepin described a NATO member attacking another as “unprecedented,” stating: “If Donald Trump goes forward, the status of the US will go from adversary or rival to the one of enemy. It’ll be a huge historical change” .

The situation has raised concerns about the future of NATO, with reports indicating a shift in US tone toward viewing a takeover as a more concrete possibility.
