Canada

This is a good assessment. For some added context, the idea of annexing Canada is astonishingly unpopular in the US. Even among Republican voters, only 25% approve. No one in the White House understands where this insanity is coming from or why, no one in the Republican party is in favour of it. It's basically just Trump and Navarro.

So while it is absolutely insane that the possibility of a US invasion exists, there's no real likelihood to it. Russians see annexing Ukraine as a good and right thing to do. They don't generally want Ukrainians to suffer - they see them as fellow Russians - but they see annexation as in their best interests. There's no such appetite in the US. The American people have zero interest in a senseless war against an ally.

But Trump is largely unchecked, and he may try anyway, no matter how much the attempt would destabilize his own nation. That's a risk we have to prepare for.

Either way, our days of treating the US as a reliable ally are over. Canadian soldiers bled and died for them in Korea and Afghanistan, and fought shoulder to shoulder with them in both world wars and multiple peacekeeping operations, and this is the thanks we get? Fuck that, and fuck every American that allowed this to happen.
