The immediate post-war period is usually described in uncomplicated terms as far as American arms control policy was concerned. States Government sought an international agreement that would have banned national nuclear weapons programs after the establishment of an effective system for the international ownership, development, and safeguarding of the technology’s peaceful uses. The advent of nuclear technology contributed to the crumbling of Washington’s designs for post-war peace. The hope for continued allied cooperation in the establishment of a secure order fell before the circumstances of Anglo-American partnership and the post-war American monopoly on nuclear arms. The official community within which arms control compromises would be wrought for policy purposes was small and easily influenced by the contrasting views of the scientists and military, depending on the issue and, inter alia, the state of international politics.
