Noting new intelligence information on the Indian and Israeli nuclear programs, as well as the possibility of developments concerning Sweden, Hughes requested McCone to initiate a new estimate of nuclear proliferation trends, which would eventually become part of a October 1964 National Intelligence Estimate (NIE). Hughes enclosed draft “terms of reference,” that included questions about the possibility of “clandestine” weapons programs and new technological developments that could make weapons development “easier” (perhaps a reference to gas centrifuge technology that the 1964 NIE would discuss).

This NIE comes to the general conclusions that “there will not be a widespread proliferation of nuclear weapons over the next 10 years” and discusses programs in various countries (Israel, China, Sweden, India, West Germany, Japan, etc.) This copy includes newly declassified references to the Israeli nuclear weapons program, including the conclusion that “the Israelis, unless deterred by outside pressure, will attempt to produce a nuclear weapon some time in the next several years.”

The UN inspection team for the supervision of the dismantling of the Soviet bases was to be made up of representatives from Sweden, Mexico and Switzerland. Switzerland feels uncomfortable with being included in the mandate, due to their representation of American interests in Cuba.

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.

In this entry, Mitrokhin draws upon KGB sources to describe Yuri Velichkov Bagomil Stanimerov (b.1941), a Bulgarian citizen who graduated from the Moscow State Institute of International Relations in 1968. Stanimerov was recruited by the Bulgarian branch of the KGB in 1970, and became a resident of Sweden in 1972. Mitrokhin’s summary of KGB documents indicates that in April 1974, CIA officer Huey Walter “Hearst” made Stanimerov an offer in the name of the National Security Council. While Stanimerov refused the offer, he told Hearst that he would continue collaborating with him. Stanimerov subsequently traveled to many foreign countries, but the Americans no longer expressed interest in him.

In 1975, Stanimerov was sent to work in the Bulgarian embassy in the United States. The Americans began to train Stanimerov as a spy and tried to ideologically convert him. The Mitrokhin account posits that the KGB gave Stanimerov instructions in case the latter succeeded in infiltrating the CIA. In 1978, the KGB received information regarding the fact that Stanimerov was being investigated by the FBI for his ties with the Bulgarian intelligence services
