Political Warfare against the Kremlin contributes to the rapidly evolving field of Cold War History by providing a comparative study of American and British propaganda policy during the first fifteen years of the Cold War. It tells the compelling story of the formulation and execution of Western political warfare efforts to confront the Soviet Union during the most hostile period of the Cold War. The narrative is told across a broad historical canvas ranging from the debates inside the top levels of the U.S. and British governments about how to confront Soviet propaganda activities, to the secret government organization tasked with planning and organizing the political warfare efforts of the West, and the story behind the West's shortwave broadcasts beamed across the Iron Curtain into the Soviet Union. Finally, drawing from the Cold War, the book provides six historical lessons that can serve as a starting point for confronting the ideological and cultural challenge posed by Islamic radicalism today.
