Professor Michio Kaku, the renowned theoretical physicist from City University of New York, examines nuclear terrorism scenarios and the terrifying possibilities facing humanity in the post-9/11 world. The Harvard-educated scientist, whose textbooks are required reading at top physics laboratories worldwide, discusses the accessibility of nuclear materials and the realistic threats posed by non-state actors seeking weapons of mass destruction. Kaku analyzes various nuclear accident scenarios, debunking the myth that nuclear power has never killed anyone while referencing suppressed incidents from his graduate school days. The conversation explores the physics behind nuclear weapons, the vulnerabilities in nuclear security systems, and how easily radioactive materials could be weaponized by terrorists. Art Bell and Kaku examine the delicate balance between nuclear energy benefits and catastrophic risks, discussing early warning systems, emergency protocols, and the psychological impact of living under constant nuclear threat in an increasingly unstable world.
