In this book Richard Kokoski examines the crucial technologies relevant for the production of fissile materials for nuclear weapons and the potential ramifications of the existence, spread and further development of these technologies for the nuclear non-proliferation regime. He analyses potential policy options which could help to ameliorate some of the resulting dangers for the NPT regime as a whole. The many issues raised by the nuclear weapon programmes in Iraq and North Korea receive special attention. The author describes the scope and state of development of the Iraqi nuclear weapon programme, as revealed by the IAEA inspections in the wake of the 1991 Persian Gulf War, and examines the challenges which this experience has posed to the non-proliferation regime. He then outlines and assesses IAEA safeguards and examines moves which could further enhance their effectiveness. His review of recent improvements to nuclear export controls, including those on dual-use items, is accompanied by suggestions for ways to further tighten these controls as well as help to prevent smuggling of fissile material.
