from V.I. Lenin, 'The Discussion On Self-Determination Summed Up' (1916)

To imagine that social revolution is conceivable without revolts by small nations in the colonies and in Europe, without revolutionary outbursts by a section of the petty bourgeoisie with all its prejudices, without a movement of the politically non-conscious proletarian and semi-proletarian masses against oppression by the landowners, the church, and the monarchy, against national oppression, etc.-to imagine all this is to repudiate social revolution. So one army lines up in one place and says, "We are   for socialism", and another, somewhere else and says, "We are for imperialism", and that will he a social revolution! Only those who hold such a ridiculously pedantic view could vilify the Irish rebellion by calling it a "putsch".

Whoever expects a "pure" social revolution will never live to see it. Such a person pays lip-service to revolution without understanding what revolution is.
