This guy has literally never spoken to a single member of the Canadian military in his life.
I know soldiers in the CAF. There is no one in Canada more gung-ho to fight the yanks than the CAF. Even the guys who used to be big Trump fans, even the far right assholes, they're all ready to throw hands. The few soldiers who still like Trump are treated as absolute pariahs right now. Everyone else accuses them of being cowards and traitors. Even if the Canadian government sent out an order to lay down arms, 90% of the CAF would ditch their uniforms and become insurgents. There's shit I've heard people say that I can't even share here because it would get people in serious trouble. Some of it because they shouldn't be saying it, and some of it because civilians like me aren't supposed to know about it.
Also, his digression about the threat modelling shows the depths of his ignorance. Yes, there are American liaison officers in Ottawa, of course there are. We're in two separate military alliances with the US. That doesn't prevent us from theory crafting about a possible US invasion, because that kind of thing is completely normal. Militaries plan for every possible eventuality because that's their job.
This video is the biggest load of horseshit I've ever seen. Every single word of it was spectacularly and outlandishly wrong in some way or another. Whatever this guy might be good at, talking about the Canadian military isn't it.
