Ultimately I agree with you but if I’m a leader of say, Canada or somewhere in the EU I wouldn’t bank on it

For one I’ve also been around many “disordered folks” as you call them (outpatient therapist) and rhetoric can escalate. This is a common behavioral pattern called an extinction burst. You stop giving into his bullshit? That’s the most dangerous time of all. Even putting that aside there’s just the risk of him getting escalating amounts of unchecked power. Those threats might get cashed once he decides he wants to check and see if he can actually get away with it.

But that aside it’s not him as much as the entourage. There’s a group behind him and some of them are clearly looking to push him towards alienating the us from all their allies. He doesn’t work in a vacuum. He has a bunch of people saying “maybe you should do this”. He even has people saying “you have to do this, I gave you x million dollars”. Again, if I’m leading Canada this is what truly worries me. Trump may be a chickenshit but the warhawks behind him that want to sell a bunch of military gear and get contracts are frothing at the mouth for this kind of thing.
