"From the 1960s until the 1990s, apartheid South Africa was an isolated state that felt threatened by growing domestic unrest, as well as by a more powerful state actor, the Soviet Union, which was helping hostile regimes and liberation movements in southern Africa. One response of the apartheid regime to changing threat perceptions outside and inside of South Africa was to develop a new and more sophisticated chemical and biological warfare (CBW) program, code-named Project Coast, and to accelerate a nuclear weapons program. Ultimately, the United States, Great Britain, and other countries pressured the South African government to ensure that the CBW program was dismantled and the former project manager, Dr. Wouter Basson, constrained. This monograph analyzes the origins and development of the South African CBW program, as well as its rollback. It concludes with a profile of South Africa as a state that produced weapons of mass destruction and with a list of outstanding questions. More than 20 policy lessons, based on the South African case, are presented, which should be considered in future CBW non-proliferation studies."
