"This position by the Leninists of the necessity for a dictatorship to protect the revolution was not proven in the Civil War which followed the Russian revolution; in fact without support of the Anarchists and other left-wing forces, along with the Russian people, the Bolshevik government would have been defeated.

Even ideological opponents in the Bolshevik party were imprisoned and put to death."
