The Communists only won the Civil War because they drafted people into their army. That isn't a revolution. That is slavery.
Clueless. The communists won because their politics was of benefit to the vast majority of the population. The old government had been conscripting soldiers into its army for years, if you ever heard of the first world war.
For example land reform for the majority of poor peasants, which similarly was a major reason why the Chinese revolution succeeded and why millions of peasants supported the communists.
The Bolsheviks had big support from workers in cities, who were starving due to speculation in food and poor due to exploitation by the capitalists, and soldiers who saw no end to the war.
As a matter of fact, the Bolsheviks and Socialist Revolutionaries were backed by the majority of the population, and not the right-wing, which despite cowardly foreign support from Great Britain and many others, failed.
