Memo reports that during the period the Carter administration was putting pressure on South Africa to avoid the nuclear weapons route, but the analysts suggested that even if the South Africans signed the NPT and accepted IEAE safeguards they would continue to pursue a “covert program.”

This report for the Energy Research and Development Administration (ERDA) pointed to downsides of US and international pressures against pariah or otherwise beleaguered states such as South Africa and Israel and against would-be nuclear proliferants. They might cooperate to advance their goals.

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 South Africa’s status as a pariah state, its nuclear program was a thorny problem for a series of U.S. presidents. In August 1977, the Carter administration, working with the Soviet Union, lodged protests against South Africa’s apparent preparations for a nuclear test, forcing a shut-down of the Kalahari test site if not the entire nuclear program itself. Indeed the CIA’s analysis of South Africa’s innovative “aerodynamic” uranium enrichment plant at Valindaba brought it to the conclusion that South Africa would be able to produce enough weapons-grade uranium “to make several nuclear devices per year.”

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.
