Quoted by a blogger, February 2011. Attributed to philosopher Jacques Ellul:

First of all, the propagandist must insist on the purity of his own intentions and at the same time,¬†hurl accusations at the enemy. But the accusation is never made haphazardly or groundlessly. The propagandist will never 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.”
