A fundamental difference between modern dictatorships and all other tyrannies of the past is that terror is no longer used as a means to exterminate and frighten opponents, but as an instrument to rule masses of people who are perfectly obedient. Terror as we know it today strikes without any preliminary provocation, its victims are innocent even from the point of view of the persecutor. This was the case in Nazi Germany when full terror was directed against Jews, i.e., against people with certain common characteristics which were independent of their specific behavior. In Soviet Russia the situation is more confused, but the facts, unfortunately, are only too obvious. On the one hand, the Bolshevik system, unlike the Nazis, never admitted theoretically that it could practice terror against innocent people, and though in view of certain practices this may look like hypocrisy, it makes quite a difference. Russian practice, on the other hand, is even more "advanced" than the German in one respect: arbitrariness of terror is not even limited by racial differentiation, while the old class categories have long since been discarded, so that anybody in Russia may suddenly become a victim of the police terror. We are not concerned here with the ultimate consequence of rule by terror—namely, that nobody, not even the executors, can ever be free of fear; in our context we are dealing merely with the arbitrariness by which victims are chosen, and for this it is decisive that they are objectively innocent, that they are chosen regardless of what they may or may not have done.
