National Intelligence Estimate, NIE 5-91C, 'Prospects for Special Weapons Proliferation and Control'

With the term “weapons of mass destruction” having not yet fully come into general usage, this NIE used the term “special weapons” to describe nuclear, biological, and chemical weapons (formerly the term “special weapons” was sometimes used to describe nuclear weapons only). With numerous excisions, including the names of some countries in the sections on “East Asia and the Pacific” and “Central America,” this wide-ranging estimate provides broad-brushed, sometimes superficial, pictures of the situations in numerous countries along with coverage of international controls to halt sensitive technology exports to suspect countries.

Central Intelligence Agency, Directorate of Intelligence, 'Argentina: Seeking Nuclear Independence: An Intelligence Assessment'

According to the 1985 report, the Argentines “have achieved at least a proof of principle of uranium enrichment via gaseous diffusion.” In other words, they had a workable system. Nevertheless, the enrichment plant would not be “fully operational until 1987-1988.” While the assessment of Argentine interest in nuclear weapons did not change, CIA analysts asserted that “Argentina continues to develop the necessary facilities and capabilities that could support a nuclear weapons development effort.”

Special National Intelligence Estimate, SNIE 13/32-83, 'Chinese Policy and Practices Regarding Sensitive Nuclear Transfers'

With nuclear proliferation a policy priority for the Jimmy Carter administration, and Pakistan already a special concern, the possibility that China and Pakistan were sharing nuclear weapons-related information began was beginning to worry US government officials. These concerns did not go away during the Reagan administration. While nuclear proliferation was not a top priority, the administration was apprehensive about the implications of the spread of nuclear capabilities and that China may have been aiding and abetting some potential proliferators by selling unsafeguarded nuclear materials.

December 7, 1979

Deputy Director for National Foreign Assessment, Central Intelligence Agency, Enclosing Report, 'A Review of the Evidence of Chinese Involvement in Pakistan’s Nuclear Weapons Program'

With nuclear proliferation a policy priority for the Jimmy Carter administration, and Pakistan already a special concern, the possibility that China and Pakistan were sharing nuclear weapons-related information began was beginning to worry US government officials. They had no hard evidence--and the soft evidence that concerned them is massively excised in the December 1979 report just as Beijing and Washington were normalizing relations—so the “precise nature and extent of this cooperation is uncertain.”

January 20, 1966

National Intelligence Estimate, NIE 4-66, 'The Likelihood of Further Nuclear Proliferation'

This estimate updated an estimate (NIE-4-2-64) published in 1964 of the nuclear proliferation problem. That estimate, like this one, overestimated the likelihood of an Indian bomb, while somewhat underestimating Israel’s program. This assessment followed the same pattern—predicting India would produce a weapon within a “few years” and also putting Israel in the “might” category, although treating it as a “serious contender” nonetheless. Also following a short discussion of the “snowball effect” (later known as “proliferation cascades” or “chains”) suggesting that the United Arab Republic (Egypt-Syria) and Pakistan were likely to take the nuclear option should India or Israel go nuclear.

October 21, 1964

National Intelligence Estimate NIE 4-2-64, 'Prospects for a Proliferation of Nuclear Weapons Over the Next Decade'

This US analysis of the likelihood of nuclear proliferation during the next decade was finished only days after the first Chinese nuclear test on 16 October. The report analyses the implications of this test, as well as programs in India, Israel, Sweden, West Germany, Italy, Japan, Canada, and others. The National Intelligence Estimate (NIE) argued that India was the only new state likely to develop nuclear weapons, concluding that “there will not be a widespread proliferation …over the next decade.”

June 23, 1963

National Intelligence Estimate NIE 4-63, 'Likelihood and Consequences of a Proliferation of Nuclear Weapons Systems'

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.”
