Research Memorandum RSB-152 from Roger Hilsman to the Secretary, 'Soviet Tactics in Talks on the Non-Diffusion of Nuclear Weapons'

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.

Research Memorandum RSB-58 from Roger Hilsman to the Secretary, 'Probable Soviet Reaction to Establishment of Multilateral NATO-Controlled MRBM Force'

George Vest to Mr. Sonnenfeldt, 'British Comprehensive Safeguards Initiative re Suppliers Conference'

This document describes the differing views regarding safeguards. The Canadians strongly supported the former, “full scope safeguards” (their terminology, which caught on), which the French saw as “tantamount to imposing NPT obligations”--a reference to the Treaty’s Article III--which they would not accept. Arguing that full-scope safeguards was “alien to [their] philosophy,” the French suggested that a “traditional interpretation of the contamination principle (i.e., requiring safeguards on any materials produced in exported facilities),” would make it possible to achieve “the practical equivalent” of the Canadian proposal.

Memorandum from George S. Vest to Secretary of State, 'September 16-17 Nuclear Suppliers' Meeting'

The September 1975 meeting of the suppliers’ group brought out a conflict over a decisive issue, whether supplying countries should require recipient countries to place all nuclear facilities under safeguards or require them only for the technology and supplies at issue in the contract (“project safeguards”). The Canadians strongly supported the former, “full scope safeguards” (their terminology, which caught on), which the French saw as “tantamount to imposing NPT obligations” --a reference to the Treaty’s Article III--which they would not accept.

Memorandum from Winston Lord, Fred Iklé, and Helmut Sonnenfeldt to the Secretary, 'Follow-up with French on Nuclear Export Controls'

While no one could be sure whether the French would abandon their “case-by-case” approach to nuclear exports, the advisers believed that the French disliked nuclear proliferation and wished to remain the only nuclear weapons state in Western Europe.
