In 1990. During reunification of Germany.
The reality is, after 40 years under the Russian Boot, the former Warsaw Pact countries and even some former Soviet Republics couldn't WAIT to join NATO.
As well as former Ukrainian regiona can't wait to join Russian
I think you are confused.
The US actually DID try to annex Canada in the War of 1812. We saw that the UK was pre-occuppied with Napoleon and tried to take advantage. We got our asses whooped for doing so.
Its all the questions of motivation. You did annex Texas, you could annex Canada if you wish.
The thing was, when the USSR broke up, Russia didn't say squat about the Donbass. They just didn't care.
They still don't care about the Donbas, it's just a pretext for aggression.
We are human beings, and we are rationally thinking human beings. We don't start aggression wars without really good reason.
Russian politician who doesn't care about Russian people, or at least, don't try to seems like he do care, very soon cease his career as a Russian politician or even cease his existence at all. And its a part of being collective animal. Collective self-defence. Attack one of us, and all of us will fight back.
So, lets play the game. New, illegal (from US point of view) Canadian regime, started discrimination and terror against pro-American Canadians. Like, say, burning alive, during on-line show, one hundred of peacefully protesting "Rednecks and Hillbillies" (exactly for being Trumpists). Do you believe that there is any force on our green Earth, that could stop the flow of American volonteers wishing to fight against pro-EU Canadian regime?
