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 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.

Information on KGB counter-intelligence surveillance of Soviet tourists vacationing in other socialist countries who had contact with foreigners. The document states that Western intelligence services organized “friendship meetings” through tourist firms to meet Soviet citizens, gauge their loyalty to the USSR, and obtain political, economic, and military intelligence. KGB counter-intelligence paid particular attention to Soviet citizens who were absent from their groups, took side trips to different cities or regions, made telephone calls to foreigners, or engaged in “ideologically harmful” conversations in the presence of foreigners. Mirokhin regrets that the KGB underestimated the strengths and methodology of Western intelligence services. He concludes that the KGB should have adopted some of the same methods, and targeted Western tourists visiting socialist countries.

U.S. demarche and "non-paper" on Pakistan's attempts to complete the plutonium reprocessing plant and develop nuclear weapons. Sent to 12 countries to ensure that they "exercise vigilance and appropriate control to deter Pakistan from acquiring sensitive facilities."

This folder contains information about KGB active measures directed at author Alexander Solzhenitsyn following his exile from the Soviet Union in 1974. The operational directives prepared by the KGB’s leadership for 1974 and 1975 are reproduced verbatim. They included plans to limit Solzhenitsyn’s influence in the West, discredit him and the pro-democracy literary journal “Continent” with which he was closely associated, and make his family fear for their personal safety.

Many of the specific measures undertaken by the KGB are described in the document. These included televised interviews with men featured in “The Gulag Archipelago” in which they claimed that Solzhenitsyn fabricated or misrepresented their statements to him, the publication of personal letters between Solzhenitsyn and his close male friends which were intended to reveal the “intimacy of their relations,” and the publication of an article claiming that Solzhenitsyn failed to pay his taxes while he resided in Switzerland. The 1978 operation codenamed “Vampire 1” involved planting a news story which suggested that Solzhenitsyn was a KGB spy, and having it reprinted in prominent newspapers and journals throughout Europe and the US. The document concludes with an index of acronyms, people, and codenames mentioned in the folder.
