They must have skipped 20th Century History at your schools, or you were playing hooky.
After the October Revolution there was the Russian Civil war which lasted for years. Ever hear of the "Red Army" and the "Whites?" Doctor Zhivago ring a bell?
Or did you just think Lenin proclaimed himself master, and the Russians all just saluted and put up red hammer and sickle flags? Sorry, you are off by a million milies. Are you even aware that American and British army brigades fought in the long and bitter Russian Civil War?
Gees, if this is the level of understanding of key parts of history on Free Republic, I shuddet to think what fills the skulls of the MTV generation.
