When the Berlin Wall came down in November 1989, it exposed a crumbling empire littered with hundreds of tonnes of nuclear material and thousands of nuclear weapons. Across Russia and the former Soviet Union, stocks of plutonium and bomb-grade uranium, as well as a wide variety of nuclear landmines, artillery shells and missile warheads were portable enough to be carried by just three people. The short-range missile warheads, small nuclear bombs, landmines and torpedo warheads could be lifted and carried by a single person and were small enough to fit into a backpack or trunk. In this account, journalists Andrew and Leslie Cockburn show that prospect criminals, extremists or terrorists might easily obtain these weapons, and that the threat from nuclear materials is dangerously real.
