Denmark's Defence Ministry has reaffirmed a standing Cold War-era directive from 1952, obliging its troops in Greenland to 'shoot first and ask questions later' if the territory comes under attack by any foreign force. This re-emphasis comes amidst renewed geopolitical tensions following former U.S. President Donald Trump's repeated expressions of interest in acquiring Greenland, an autonomous territory within the Kingdom of Denmark. Trump, who had previously floated the idea in 2019, has reportedly revived his efforts to purchase Greenland after his 2024 re-election, with some reports indicating threats of invasion or annexation. The White House, at one point, stated that the 'U.S. military is always an option at the commander in chief's disposal' regarding Greenland, further escalating concerns. Danish Prime Minister Mette Frederiksen has consistently rejected any notion of selling Greenland, asserting that the island is 'not for sale' and that any military action against a NATO ally would signify 'the end of NATO'. Greenlandic officials have also vehemently affirmed their right to self-determination and have stressed that the island belongs to its people. European leaders and allies have rallied behind Copenhagen, calling for collective action and respect for international law and Greenland's territorial integrity. The renewed dialogue includes a planned meeting between US Secretary of State Marco Rubio and Danish and Greenlandic officials to discuss the situation.
