On 9 April 1940, the day that Denmark fell to the Nazi war machine, the Danish envoy to the United States, Henrik Kauffmann, in violation of his diplomatic status, signed an agreement authorising the US to act as defenders of Greenland and build military installations there.

Analysts say the Cold War agreement allows the president to increase the American military presence almost at will.

The United States special envoy to Greenland posted a misleading historical claim about the territory he is tasked with planning to take over. “History matters,” Gov. Jeff Landry wrote on X, before sharing information that was not historically accurate.
