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.

Seeking “constructive engagement” with the apartheid regime, the Reagan administration wanted the South Africans to keep a lid on their nuclear weapons program. The NIE’s top-secret status was compatible with one of the elements of the 1984 estimate: that any revelations that broke the regime’s “calculated ambiguity” about its nuclear status would put Washington in an “awkward position” by “fir[ing] the drive” for the sanctions and disinvestment campaigns which the administration was trying to avoid. Analyzing the motives for the nuclear program, the CIA found it “irrelevant” to any threat that the regime was likely to face.A key issue was whether South Africa had a nuclear arsenal. On that problem, the NIE dovetailed with the view taken by NIE-4-82: South Africa “probably has the capability to produce nuclear weapons on short notice.” That was accurate, but U.S. intelligence may not have known that the regime’s leaders had already decided to build a stockpile of 7 weapons, with six weapons assembled during the 1980s.

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.

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.
