One of the most effective and devious methods of mass deception is falsely accusing others of one’s own misdeeds…

“The propagandist will not accuse the enemy of just any misdeed; he will accuse him of the very intention that he himself has and of trying to commit the very crime that he himself is about to commit. He who wants to provoke a war not only proclaims his own peaceful intentions but also accuses the other party of provocation. He who uses concentration camps accuses his neighbor of doing so. He who intends to establish a dictatorship always insists that his adversaries are bent on dictatorship.”
