The memorandum describes a difference between President Carter and the West Europeans over their commitment to limiting reprocessing and plutonium supplies for R&D work on breeder reactors.

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 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.

In this document regarding the final agreement, George Vest wrote Kissinger that it “served to close many of the loopholes and inadequacies of previous nuclear cooperation agreements between suppliers and recipients.” It also put the French and West Germans on record to restrict access to sensitive nuclear technologies. Nevertheless, as Vest noted, the guidelines would not prevent “indigenous” development of nuclear capabilities and “unsafeguarded developments” or the acquisition of sensitive technology.

Memo of suggested issues to be discussed at meeting regarding nuclear suppliers' conference, specifically what to say to other suppliers regarding recent bilateral talks between France and the U.S. and further instructions for the French-U.S. bilateral talks regarding France's participation in the nuclear suppliers' conference.

In the course of a background paper on the nuclear proliferation problem and policy options, the State Department updated the White House on the state of play of the nuclear suppliers’ initiative: the British, the Canadians, and the Soviets had agreed to attend a meeting; the Germans would agree “if all key suppliers” (France) accepted; and the Japanese, who had also been asked, had not responded. The French had not given an answer and bilateral discussions would take place to go over the issues.

Kissinger agreed that in his absence Acting Secretary of State Robert Ingersoll and ACDA Director Fred Iklé should meet with French Ambassador Kosciusko-Morizet and that the British, Germans, and Canadians should receive copies of the five-point paper, and also be informed of the approaches to the French and the Soviets.

Kissinger presided over an important staff meeting in early August where he made a decision to go ahead with the suppliers’ project, beginning with approaches to Moscow and Paris. While noting that the U.S., as a sponsor of the NPT, had a “special responsibility” to curb nuclear proliferation, Kissinger did not believe that it had a unique responsibility

To help Kissinger prepare for a follow-up discussion, ACDA and State Department officials prepared a "Non-Proliferation: Strategy and Action Program” to help guide policy. A key proposal was for “high level political approaches to key exporting countries to enlist their support for safeguarding transfers of nuclear materials.” While Washington had to approach a number of nuclear exporters, consultations with France “constitute the most crucial and urgent step to be taken.”
