Denmark has reaffirmed that its military is prepared to defend Greenland with force if any foreign power attempts to seize the territory, including the United States. The Danish Defence Ministry confirmed that a long-standing Cold War-era directive from 1952 remains active, requiring troops to respond immediately to an invasion without waiting for orders.
Under this rule of engagement, Danish forces must open fire and resist any armed attack on Greenland, which is an autonomous territory under Danish sovereignty, as soon as hostile actions are detected. The policy was originally adopted following Denmark&rsquo;s experience in World War II to ensure rapid defence in cases of surprise attacks and has been confirmed to still be in force.
The renewed focus on the rule comes amid increasing rhetoric from the US administration about Greenland&rsquo;s strategic importance and the possibility of the United States seeking greater control or influence over the Arctic island. Denmark and Greenland have consistently opposed any suggestion of transfer of sovereignty or military takeover, emphasising that Greenland is not for sale.
European and NATO allies are closely watching developments, with concerns that any attempt to alter Greenland&rsquo;s status by force would strain alliance relations and challenge international norms. Denmark has also called for diplomatic engagement to address security and political issues surrounding Greenland&rsquo;s future.
