I regret, but you are either badly misinformed or else totally dumb.
When the Wall came down in 1989 (thanks to Gorbachev), he was promised (as part of the deal to reunify East & West Germany) that there would be no further NATO expansion eastwards. You can check this out here:

Declassified documents show security assurances against NATO expansion to Soviet leaders from Baker, Bush, Genscher, Kohl, Gates, Mitterrand, Thatcher, Hurd, Major, and Woerner Slavic Studies Panel Addresses “Who Promised What to Whom on NATO Expansion?”
Since then NATO has expanded into 12 countries further eastwards. The Soviet Union (then) and Russia (now) was lied to, duped and "conned"by the USA (who basically run NATO) in to believing that it could trust the West. I am no supporter of Putin but I can sure understand why he is so pissed off!
