You really should consider easing up on the certainty of your positions in regards to what Trump will or won't do.
1) I absolutely hope you are right, and he would indeed face major static if he attempted military action against Greenland or Canada. In all likelihood, it's all just bluff and bluster.
2) As others have pointed out, he absolutely cannot be trusted, especially now since the adults that were present in the room during his first term are all gone. If he does attempt a military move against either, I will absolutely come back here and glare at you in digital fashion.
