South African nuclear development in the 1970s: A Non-proliferation conundrum?

The 1970s is often argued to be the era marking the beginning of the overall transformation of the international system and the nuclear order, following the Nuclear Non-proliferation Treaty (NPT) entering into force in 1970. South Africa challenged this nuclear order from the outset. In addition to regarding the NPT as inherently discriminatory and hypocritical in allowing a difference between nuclear weapon ‘haves’ and ‘have-nots’, the South African apartheid regime felt threatened by Soviet expansionism into Southern Africa. Facing international condemnation and isolation due to its repressive domestic politics of racial segregation, and gripped in a war against Soviet- and Cuban-backed forces in Angola, the apartheid regime was quick to move from a decision to build one peaceful nuclear explosive device in 1974, to a formal decision in 1978 to design and develop a secret strategic nuclear deterrent. Using knowledge and skills acquired during a period of techno-nationalism and Western collaboration during the 1960s, South Africa was able to cross this threshold in a relatively short space of time, thereby signaling a clear departure from the nuclear non-proliferation regime that the five nuclear powers of the NPT were trying to establish.
