ichi // I don't know from where you receive your information, probably from the BBC & assorted American-fed media.
I happen to be married to a historian, who specialises in European history, I haven't read anything like the amount she has, but I get distillations in conversation.
I found last night this very good Wikipedia site, which I think gives just about as impartial a view of the past & present as is possible at this moment. It doesn't portray Vladimir Putin as a saint, but it doesn't vilify him as the pantomime villain you do either.
I hold no particular brief for the East or West, I just seek a clear honest view of the situation overall.
Why not take a look ?
