After Venezuela, Trump has threatened Cuba, Greenland, Iran, and Mexico in the same breath. He called Colombia “Very Sick” and claimed Cuba “is ready to fall.” How many likely Countries is Trump Going to Invade?

Greenland belongs to Kingdom of Denmark , might as well threaten all of NATO. 

They have already been prepping for an attack on the cartels at the border of Mexico for awhile now, they will hit Colombia and Iran again first.
Cuba will fall apart on its own without Venezuela support and Greenland will just let them mine the rare earth minerals without any fighting.

I am no military strategist, but on some level it does make sense to control what you can control as a super power having and maintaining a buffer in your own backyard. Columbia and Cuba are potential footholds for countries with anti-US goals. Greenland is militarily strategic with an obvious resource-driven motive as a bonus.

He will invade as many as the other two branches of Government and US citizens allow him to. I don’t see him stopping anytime soon. I genuinely believe the goal is WWIII and/or one government in which he and the oligarchy lead.
