Although in the early 1990s, nearly fifty countries had a nuclear capacity, and many more were close to it, only a handful were actually in possession of nuclear weapons. David Fischer’s book, originally published in 1992, was of particular interest in the light of the collapse of the post-war power structure, and the intensive militarization in the Middle East at the time, addresses the problem of how to prevent the wider acquisition of such weapons. Fischer surveys the success of the international regime set up to stop the spread of nuclear weapons since the mid-1960s, in particular the fact that since 1968, 138 nations had renounced the bomb (now up to 190). The strengths and weaknesses of the non-proliferation treaty, and the reasons the author believes its membership should extend to France and China are discussed as is the 1995 conference that would decide the future of this treaty. Evidence is provided of the relationship between the development of nuclear power and the acquisition of nuclear weapons and of the dangers involved in the growing use of plutonium and the building of nuclear submarines. The book attempts to provide a detailed and comprehensive view of the ongoing conflict between nuclear deterrence and non-proliferation and to look at both the short- and long-term prospects for non-proliferation. Today it can be read in its historical context.
