The renewed debate over Greenland, driven by fresh expressions of interest from the United States and firm resistance from Denmark, has revived historical parallels with an earlier episode when Copenhagen transferred territory to Washington. Denmark, which is roughly 0.44 per cent the size of the US yet retains sovereignty over Greenland, has cited a 1952 Cold War–era military directive instructing its forces to “shoot first, ask questions later” in the event of an incursion. Recent remarks from the US President, suggesting the possible use of force to seize Greenland have prompted strong reactions across Europe. The statements have caused particular concern given that the United States already maintains a military base in Greenland.
