Russia - Union of Soviet Socialist Republics
Germany - National Socialist Workers Pary
Iraq - Ba'ath Socialist Party
Tell me how these are any different...
Before I answer your question, I need to be clear about something: are you actually arguing that there is no real difference between Soviet Communism/Stalinism, German National Socialism, and Iraqi Ba'athism?
Because if you are actually taking that position, I would first refer you to an undergraduate political science textbook before trying to explain the differences between all the political ideologies of the world.
