Book excerpt: This is a political history of nuclear weapons from the discovery of fission in 1938 to the nuclear train wreck that seems to loom in our future. It is an account of where those weapons came from, how the technology surprisingly and covertly spread, and who is likely to acquire those weapons next and most importantly why. The authors’ examination of post Cold War national and geopolitical issues regarding nuclear proliferation and the effects of Chinese sponsorship of the Pakistani program is eye opening. The reckless “nuclear weapons programs for sale” exporting of technology by Pakistan is truly chilling, as is the on-again off-again North Korean nuclear weapons program.
