For his source materials he drew upon official and military intelligence reports, extensive OSS interviews with refugees, and special OSS agents and contacts in occupied Europe; it was his duty to evaluate the reliability of each of the items of intelligence that reached him, and assemble them all into a coherent analysis of points of strength and weakness in the Reich." (Katz, 1980:116). At the end of 1944, Neumann, Marcuse, and Kirchheimer were involved in preparing materials for use by eventual occupation authorities, including a De-nazification Guide. Most of this effort was rendered irrelevant by the priorities of the incipient Cold War policy at the end of the war. Neumann was detached from Washington Service until September 1945, to assist the head of OSS in preparing for the War Crimes Prosecutions. Just before the beginning of the trials, Neumann returned to Washington, to take up a position on the Central European Desk of the Department of State. Nuremberg, Berlin, New York In the service of the Nuremberg War Crimes Tribunal under the Chief Prosecutor, Justice Robert H. Jackson, Neumann prepared analyses of the twenty two Nuremberg defendants and of various Nazi organizations. From mid-September 1945, Neumann's team prepared and supervised materials for a series of indictments with other OSS colleagues responsible for both interrogation and document analysis. William Joseph Donovan initially directed Neumann to examine religious persecution other than against Jews under the Nazi regime. The report's analysis of "the problem of establishing criminal responsibility" contributed to the prosecutorial strategy. The thinking was to show that measures taken against the Christian churches were an integral part of National Socialism. It also attempted to show that measures were criminal from the standpoint of German or international law, depending where a given act was committed. The report claimed key articles of the Weimar Constitution "were never formally abrogated by the National Socialist regime, … were left untouched and still remain theoretically in force." Furthermore, "respect for the principle of religious freedom" continued to be reiterated in various official policy statements of the Nazi regime, and in various "enactments of the National Socialist state, particularly the Concordat of 20 July 1933." The material on religious persecution is placed in the wider context of how these agencies committed crimes against humanity as an integral part of the Nazi's master plan, its conspiracy to seize and consolidate ideological control and totalitarian power within Germany by
