The notion that Hitler's Third Reich was a monolithic and efficient dictatorship has by now been safely buried, although it may persist in the popular imagination. This essay is intended as a contribution to the newer phase of the historical postmortem on National Socialism, the attempt to trace the precise mechanism of decision-making and internal policy-diversion in the Third Reich. Distortion of policy, as the result of disagreements among leaders or of bureaucratic sabotage, is a feature common to all modern political systems. In the grim context of the Third Reich, all attempts to distort or divert policy which tended to ameliorate inhuman aspects of Hitler's rule have been dignified by the term “resistance.” This study will show that successful local resistance was possible, even to the SS, perhaps the most powerful political force in the wartime Reich. The inquiry has its juridical aspects, since admission of the existence of successful resistance to policies and organizations declared by international and German courts to have been criminal, resistance even by those who accepted the basic premises of the regime, implies a varied distribution of criminal guilt. This distribution will not be attempted here, but the judicial analogy should not be forgotten. The historian is relieved of the responsibility of passing sentence, but, like the judge, he is concerned with more than the determination of individual actions. An understanding of the political system of Hitler's state requires as well an investigation of motivation.
