Despite new information that the Soviet Union was deploying anti-ballistic missile defenses around Moscow, the United States had not yet decided to deploy its own ABM defenses (although a decision would be made later in the year) and there was some hope that U.S.-Soviet talks would prevent an ABM race. If, however, talks failed, some NATO allies worried about the “adverse consequences” of an ABM race, especially whether having an ABM system might incline Washington toward risk taking.

Concerns about the credibility of US nuclear deterrence generated Supreme Allied Commander Europe (SACEUR) General Lauris Norstad’s proposal for a NATO-controlled medium-range ballistic missile (MRBM) force. This lengthy report represented INR’s assessment of “present and future European interest in national or multinational nuclear weapons capabilities,” including the MRBM proposal, and the extent to which an “enhancement of NATO's nuclear role” could “deter national or multinational European nuclear weapons programs.”

This lengthy report was State Department Bureau of Intelligence and Research's contribution to the first National Intelligence Estimate on the nuclear proliferation, NIE 100-6-57. Written at a time when the United States, the Soviet Union, and the United Kingdom were the only nuclear weapons states, the “Fourth Country” problem referred to the probability that some unspecified country, whether France or China, was likely to be the next nuclear weapons state. Enclosed with letter from Helmut Sonnenfeldt, Division of Research for USSR and Western Europe, to Roger Mateson, 4 June 1957, Secret

This document describes the progress made up to that point and the various concerns of countries within the group regarding the scale of safeguards, particularly from the French and Germans. The NSG also agreed to make the guidelines available to the IAEA so that it could publish them. The State Department had been reluctant to publish them, not least because they did not include full scope safeguards, but overriding that was an interest in dispelling Third World concerns about a “secret cartel.”

This document describes the meeting of 15 nuclear supplier states in London where issues were discussed such as full-scope safeguards, including sanctions in the guidelines, purpose of supplier consent, moratoriums, enlargement of membership, and various countries' individual concerns were voiced and addressed.

This document provides an overview of the London Nuclear Suppliers' Meeting which included the addition of the five newest countries to the original seven. Most old and new members were receptive when Washington lobbied them to support a “long term and stable regime of restraint” on the export of sensitive enrichment and reprocessing technology. While the French were supportive of the moratorium proposal, the Germans were uncomfortable with it, not least because of the implications for their deal with Brazil.

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.

Telegram illuminates the U.S. –French dialogue over safeguards and other provisions in the nuclear suppliers’ guidance. 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.

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.

This document summarizes the nuclear suppliers' meeting on June 18-19. Topics covered included whether safeguards should apply to the entire nuclear fuel cycle (later known as “full-scope” safeguards). Another issue was whether multinational auspices for reprocessing and enrichment plants should be mandatory or a matter of discretion by a supplier country. On these matters and others, the French position was central.
