"Accually the first russian in charge of USSR was Michael Gorbachev whose policy fred Poland and disbanded USSR"
Incorrect. Khrushchev was Russian (http://www.cnn.com/SPECIALS/cold.war/kbank/profiles/khrushchev/) Brezhnev too, born in Ukraine but his parents were Russian (http://www.cnn.com/SPECIALS/cold.war/kbank/profiles/brezhnev/). Gorbachev freed Poland and disbanded USSR? Maybe, but inadvertently. Gorbachev gave orders to OMON to shoot protesters in Vilnius. USSR was not as much disbanded by anybody as crumbled under its own weight.
And what about Lenin? Wasn't he Russian? Were not Bolsheviks Russian Party? (Russian Social Democratic Labor Party). There are many historians (e.g. Richard Pipes) who say that USSR had less to do with communist ideology, and more with Russian imperial tradition. In other words communism was a prop for the tumbling Russian empire. I think totalitarianism was a constant part of Russian politics since the times of Ivan the Terrible. You seem to be very much impressed by the fact that Stalin was Georgian. But Catarina II was German, and all her successors too. And so what? President Eisenhower was German too. And so what?
