In this classic study, American Jewish writer Alfred Lilienthal critiques the principle of dual nationality implicit in Zionist ideology, and exposes the negative impact of the Zionist idea on the vast majority of the world's Jews, who simply desire to live as equal citizens in their respective countries. In analyzing the pitfalls of the principle of dual nationality, and the related notion of dual allegiance, Lilienthal details the activities of Zionist organizations in the United States in the 1950s and 1960s. He discusses the various forms of political pressure these organizations used to influence U.S. foreign policy during that period, uncovering the negative impact on U.S. foreign policy in general and the adverse consequences for American Jewry.
