Can't imagine many American troops would be eager about heading to Greenland at anytime. Does Trump ever think he falls right into Putin's hand, as if Putin decided to go further than Ukraine like say Poland, he can throw back that the US invaded Greenland so... what is right or wrong? Can tell someone off for invading someone then do the same thing yourselves.
Horrible times for the people of Greenland, no threat to anyone yet could face being attacked.
