Before the words “nuclear nonproliferation” entered official discourse, the term “non-diffusion” (or “non-dissemination”) of nuclear weapons was used routinely. In part stemming from the negotiations over Berlin, during 1962-1963 the Kennedy administration held talks with allies and adversaries on the possibility of a non-diffusion agreement which included Germany. In light of a recent Soviet proposal, INR veteran Soviet expert Sonnenfeldt explained why Moscow had moved away from earlier proposals singling out West Germany and was focusing on the general applicability of a non-diffusion agreement.
