If the United States attacks Greenland, first there will be gunfire, then questions: Denmark

Denmark’s Ministry of Defence has issued a stark warning to the United States: if American forces attempt to intervene militarily in Greenland, Danish troops will “fire first and ask questions later.” The statement reflects a long-standing military protocol established in 1952, which stipulates that soldiers do not need to wait for orders from superiors to repel any intruder.

When approached by the Danish newspaper Berlingske about the current relevance of this directive, the Ministry confirmed that it remains fully in effect.

The warning comes amid renewed US interest in Greenland, a NATO territory, following comments by President Donald Trump signalling that Washington is considering multiple options—including military intervention—to secure control over the Arctic island.

Trump Administration’s Plans for Greenland
White House Press Secretary Karoline Leavitt stated: “President Trump has made clear that acquiring Greenland is a priority for US national security. It is vital to prevent adversaries from gaining a foothold in the Arctic. The President and his team are exploring various options, with the use of military force explicitly remaining an option under consideration.”

Meanwhile, US Secretary of State Marco Rubio has indicated plans to meet with Danish and Greenlandic officials next week. According to The Wall Street Journal, Rubio emphasised that the intention is not military action, but rather a potential purchase of the island—a proposal Denmark has welcomed as a “necessary dialogue.”

Vice President JD Vance, however, suggested on Wednesday that Denmark has “clearly failed” in securing Greenland, adding that President Trump is “prepared to take whatever steps are necessary” to protect US interests in the Arctic region.

Denmark and European Response
Denmark has repeatedly stressed that Greenland is “not for sale.” European leaders issued a joint statement last Tuesday warning President Trump to respect both Greenland’s and Denmark’s regional sovereignty.

Danish Prime Minister Mette Frederiksen also issued a direct warning, stating that any US military aggression would effectively end NATO as it stands and mark the collapse of post-World War II security structures.

Trump’s rationale centres on the growing strategic threats posed by China and Russia in the Arctic. Control over Greenland, he argues, is essential to ensuring US security in the increasingly contested polar region.
