In his shocking and revelatory new work, celebrated journalist William Langewiesche investigates the burgeoning threat of nuclear-weapons production and the inexorable drift of nuclear-weapons technology from the hands of the rich into the hands of the poor. As more unstable and undeveloped nations acquire the ultimate arms, the stakes of state-sponsored nuclear activity have soared to frightening heights. Even more disturbing is the likelihood of such weapons being used by guerrilla non-state terrorists. The author also recounts the recent history of Abdul Qadeer Khan, the scientist at the forefront of nuclear development who single-handedly peddled nuclear plans to North Korea, Iran, and other potentially hostile countries. He then examines in dramatic and tangible detail the chances for nuclear terrorism.
