"'I understood the infamous spiritual terror which this movement [the Social Democrats] exerts, particularly on the bourgeoisie, which is neither morally nor mentally equal to such attacks; at a given sign it unleashes a veritable barrage of lies and slanders against whatever adversary seems most dangerous, until the nerves of the attacked persons break down... This is a tactic based on precise calculation of all human weaknesses, and its result will lead to success with almost mathematical certainty...
I achieved an equal understanding of the importance of physical terror toward the individual and the masses... For while in the ranks of their supporters the victory achieved seems a triumph of the justice of their own cause, the defeated adversary in most cases despairs of the success of any further resistance.'
No more precise analysis of Nazi tactics, as Hitler was eventually to develop them, was ever written."
