Canada

Here's the thing. The way the American highway system works is it goes from city to city. And millions of people in the northern cities voted against him. We don't need to shut down the roads in the rural red areas. His Canadian state idea also wasn't a part of his campaign and many Americans still think it's nothing more than him being his normal blathering self. So we aren't seeing true opposition get captured in polling yet.

I agree that he's dangerous. And I don't know what we could do to stop him but I am absolutely sure the military would suffer high rates of desertion compared to orders to invade Panama, Mexico, or Venezuela. I am also sure that Congress would not use the war powers act to stop him in any invasion, nor would he listen to them if they did. So whatever has to happen is up to the people, and there are at least 80 million pissed off Americans right now. You're right that I can't guarantee anything on their behalf. I can only offer an inside perspective and my apologies.

Yeah, I’m not really sure Americans would shut down their country at this point. For one thing, they seem incapable of protesting. More importantly though, Republicans seem fully sold on an invasion and even some Democrats seem rather excited to use us to “move their politics left” (as if we’d get the right to vote)
