Once again diprount_tomato was talking about countries outside of the u.s.s.r., those inside were there before, sometimes for centuries. But even inside the u.s.s.r., they weren't forced to stay once it dislocated, despite being much more integrated than the u.k. ever was, not sure we could tell the same about the u.s.a. if one of your states decided to leave
For Finland, you're absolutely right for the first link you provided about the Winter war, thank you very much for the correction, i already knew about the Molotov cocktails named after their enemy so i should have remembered, seems like they were still salty about this loss of territory, i.d.k., yet i also provided arguments in favor of an initial "hunky dory" relation, it's possible that it degraded over time for reasons other than merely territorial, perhaps like in Ukraine, i wouldn't be surprised if Finland was used as an anti-communist spearhead and that security reasons weren't that much of an excuse. Some further reading would need to be done.
As for the baltic states, they were in the russian empire as well, before the u.s.s.r., you can't blame them for refusing to destroy everything once they took power, we wouldn't have done so in their position.
And once again Poland wasn't part of the u.s.s.r., cf. my remarks on the puppet states if that's the road you want to take. I could agree that states of the Warsaw pact were influenced by their leaders just like countries in the n.a.t.o. are influenced by their american leader.
What you called soviet invasion and american liberation would have been called exactly the opposite by the french communists.
And you may be interested to know what kind of government Taiwanese had until 1987(, as well as Hong-Kong before 1984), or not, i'm just saying. Bye :)
