    National Intelligence Estimate, NIE-4-82, 'Nuclear Proliferation Trends Through 1987'

    With proliferation becoming a “greater threat to US interests over the next five years,” intelligence analysts believed that the “disruptive aspect of the proliferation phenomenon will constitute the greater threat to the United States.” While the estimators saw “low potential” for terrorist acquisition of nuclear weapons, the likelihood of terrorist/extortionist hoaxes was on the upswing. Significant portions of the NIE are excised, especially the estimate of Israel’s nuclear arsenal and its impact in the Middle East. Nevertheless, much information remains on the countries of greatest concern: Iraq and Libya in the Near East, India and Pakistan in South Asia, Brazil and Argentina in Latin America, and the Republic of South Africa, as well as those of lesser concern: Iran, Egypt, Taiwan and the two Koreas.

    Special National Intelligence Estimate, SNIE 91-2-82, 'Argentina’s Nuclear Policies in Light of the Falkland’s Defeat'

    Argentina, like its neighbor, Brazil, was determined to develop an “independent nuclear fuel cycle,” with the capacity to reprocess plutonium and enrich uranium. Also like Brazil, Argentina was one of the few Latin American countries to refuse to sign the Nuclear Nonproliferation Treaty. Thus, Argentina’s nuclear activities were under routine scrutiny to see if they involved anything that suggested an interest in a weapons capability. US intelligence agencies continued to monitor developments but perspectives shifted as Argentina’s domestic politics evolved. Prepared after the Argentine-British conflict over the Falklands Islands, in which Washington helped London, this special estimate professed “great uncertainty” over Argentina’s nuclear intentions. While “emotionally” the Argentine military leadership was interested in a weapons option, it had “reduced capability to fulfill this desire.”

    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.

    Special National Intelligence Estimate, SNIE 93-83, 'Brazil’s Changing Nuclear Goals: Motives and Constraints'

    Brazilian nationalism has often posed a challenge to US official precepts on the way the world should work and these estimates convey the deep Brasilia-Washington gap over nuclear policy during the 1980s. The SNIEs from 1983 and the 1985 update emphasize Brazil’s quest for technological-industrial autonomy which in nuclear terms meant developing an indigenous program to master the fuel cycle, including uranium enrichment and plutonium reprocessing capabilities. In seeking those objectives, Brazil did not want to face any constraints, and its leaders were unresponsive to U.S. or other pressures for safeguards on nuclear facilities.

    Special National Intelligence Estimate, SNIE 91/3-84, 'Argentina’s Nuclear Policies Under Alfonsin'

    Almost two years after the 1982 SNIE, the military rule had collapsed and a democratically-elected government led by Raul Alfonsin was taking an unambiguous stand on nuclear weapons. In its 1984 assessment, the intelligence community was more certain about Argentina’s nuclear policies: “on the basis of discernible evidence … Argentina does not have a program to develop or test nuclear explosives.” Nevertheless, Alfonsin was unlikely to change “Argentina’s long-term efforts to achieve its goal of acquiring a full range of nuclear-fuel-cycle facilities.”
