The Nuclear Non-Proliferation Treaty represents the cornerstone of efforts by the international community to prevent the proliferation of nuclear weapons while ensuring that the benefits of nuclear technology are readily available for peaceful purposes. This publication details the Treaty and brings together, for the first time, key documents relating to the nuclear non-proliferation issue. Complementing the documents are a detailed chronology and an introduction by Secretary-General Boutros Boutros-Ghali, which provide an overview of the key role played by the Organization and its Member States in meeting the new and intrinsic challenges of the nuclear age.
