The final volume in Richard Rhodes’s prizewinning history of nuclear weapons offers the first comprehensive narrative of the challenges faced in the post-Cold War age. The past twenty years have transformed our relationship with nuclear weapons drastically. With extraordinary depth of knowledge and understanding, Richard Rhodes makes clear how the five original nuclear powers–Russia, Great Britain, France, China, and especially the United States–have struggled with new realities. He reveals the real reasons George W. Bush chose to fight a second war in Iraq, assesses the emerging threat of nuclear terrorism, and offers advice on how our complicated relationships with North Korea and South Asia should evolve. Finally, he imagines what a post-nuclear world might look like, as only he can.
