“It was assumed that entire societies could be transformed and changed in a relatively short span of time if only enough people were prepared to accept and follow the principles and priorities set by a vanguard in possession of those timeless standards.

This could be done in one step through violence or gradually through persuasion, threats, reeducation, disenfranchisement, dispossession of property, relocation, coercion, blackmail, denunciation, and, if necessary, terror.”
