Professor Nathans has written an examination of the conduct of a leading official of the Nazi administration of justice who was tried after the war, a history of German citizenship policies, and an analysis of postwar West German debates about the weaknesses and strengths, possibilities and deficiencies, of republican forms of state and society, via an examination of the work of a prominent West German journalist who analyzed the United States in radio and television broadcasts. Nathans’ current research project focuses on the history of one of the causes of the rise of an authoritarian movement in the United States, the decades-long experience of economic distress that has led large numbers of Americans to reject the republican political order.
