Book excerpt: The fact that Auschwitz, Hiroshima, and Rwanda cast ominous shadows forward into the future compels us to confront these horrific results of the human head, heart, and hand. In Genocidal Temptation, Robert Frey presents a compelling, integrated focus directed toward the Nazi killing programs, American atomic bombings in Japan, Tutsi massacres in Rwanda, Soviet genocide in Lithuania, and other mass killing and repression programs.
