Petulant lying letters to ambassadors now, eh?
There is only one country threatening to invade #Greenland by force, and its head of state is doing so openly for all the world to see.
The sad thing about all this is that Greenland has been coöperating with the U.S.A. over the latter's security since the 1950s. This will go down in history as how the spoiled brat ego and avarice of a stupid monarch and xyr toadies wrecked it all.
