How are the decisions made which produce the phenomenal arsenals of nuclear weapons in the world today? Who makes them? To whom are they answerable? What role does Parliament play? These questions have until now been shrouded in mystery. But until the answers to them are widely and openly known, those who are concerned about the build-up of nuclear arsenals cannot know how the process works, and to whom they should address themselves. That is why this book is a breakthrough. It explains, for the first time, how nuclear weapons decisions are made in each of the nuclear nations. The Oxford Research Group has brought together, entirely from non-classified sources, a mass of information to throw light on a hitherto invisible and unaccountable process.
