Yeah, invasion? Goddamit, no, nobody thinks like that here and you're doing yourself no favors if you think we do. (Well, perhaps WWII trauma does result in some paranoia about invasion, but generally no). Fear of shenanigans that will result in another political division and another nineties? Hell yes. It's the paranoia of the last ten years. One of Putin's major advantages is the fact that he's not Yeltsin.
Also, belief that a confrontational policy towards NATO would result in a better economic or political position for Russia in the long run? We have that here. Whether it's substantiated or not, it's not for me to say, I can't into geopolitics. Also revanchism. It's pretty popular.
I dunno, after some reading, modern Russia seems a bit like 70s America in the politics sense, what with the militarism and the jingoism and the counterculture and the things. Add an extra helping of Glorious Past about which nobody is exactly sure if it was actually Glorious or not, mouth-frothing reactionaries, tear-guzzling liberals who can't make their mind on whether they're social liberals or economic liberals, and a dash of not being sure on which of those are just thieves and which are genuinely crazy, and there you have us. Except that 70s America could afford such stuff because it was America, and there was nobody to try and exploit the divide.
I mean, I would pick no other place to be born in, but it's a little crazy sometimes even without the foreign affairs shitstorm. A lot of people vote for Putin just because he seems uncomplicated. That's a bit stupid, but very understandable if you try living in this political climate for a bit.
It's full of Russians, for one thing.
As a Russian internet adage goes, "And you say that as if that's a bad thing".
