This report gives an overview of Yugoslavia’s nuclear program and its tight links with both East and West in terms of financial aid and training programs

According to intelligence reports, the French were trying to acquire from US firms the diagnostic technology needed to measure a nuclear explosion. INR did not believe that France had identified a specific test site and noted that France was under pressure to hold a test somewhere other than North Africa; nevertheless it went ahead with one in Algeria in early 1960.

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 reflects that while full-scope safeguards had wide support in the group, both the French and the West German remained opposed. The Carter administration tried to persuade the French but they were worried about being "isolated" in the group and talked about withdrawing or opposing further meetings because the NSG had “fully achieved” its objectives. Washington persuaded Paris not to withdraw, but the group’s future was plainly uncertain.

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 telegram describes what the nuclear suppliers' countries accomplished during their November 11-12 meeting. Continued discussions of safeguards and enlarging the group, and agreed that they would wait on publishing results until after their next meeting, which was scheduled to be the following March in London.

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.

This document comprises the instructions which the White House approved for the September 1975 suppliers’ meeting. At the November meeting, the suppliers completed negotiations on guidelines. Basic provisions included agreement to seek assurances by recipients of supplies not to produce nuclear explosive devices, physical security for installations and materials, transfer of trigger list items only under IAEA safeguards, restraint in transfer of sensitive technologies, facilities and materials, and the encouragement of supplier involvement in, and multinational controls over, sensitive installations. Appended to the guidelines was a two page “trigger list” based on the Zangger Committee’s list.
