ABSTRACT
South Africa's nuclear disarmament is a unique historical case, notable in part for the dramatic shift from deception to cooperation. The unprecedented transparency it demonstrated in order to convince the international community of the veracity of their disarmament is heralded as an exemplar for verifiable denuclearization. Less known is how this case affords insights into how a nuclear weapon program can be clandestinely hidden by the ambiguity provided by an otherwise completely legitimate, peaceful, nuclear energy program. Using a variety of open sources, including newly declassified internal South African and US government reports, it can be shown that South Africa employed a variety of deceptive tactics before it disarmed, and even for nearly two years after becoming a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons. This article reviews that information to derive instructive lessons on the lengths that a nuclear proliferant state might go to conceal its true capabilities and intentions, and to thwart international discovery of the existence and full extent of an existing—or, in this case, a former—nuclear weapon program.

2. Both Iraq and Libya, as NPT signatories, employed similar subterfuge to conceal their unsuccessful clandestine nuclear weapon programs from IAEA inspectors. Valuable nonproliferation lessons learned can be similarly derived from the revelations derived from each country's rollback (involuntary and voluntary, respectively).

11. Stumpf, “South Africa's Nuclear Weapons Program,” p. 4. For India, it may have been “ambivalence,” but for South Africa it is more accurately “pointed ambiguity.” South Africa wanted a capability to fire a warning shot. PNEs offered them the initial step in that direction. The exposure of the Kalahari test site preparations in 1977 and subsequent international outcry effectively negated that first option.

Those authors correctly point out that the role of the Afrikaner Broederbond (AB)—the secretive, all-male, Calvinist, Afrikaner organization—was not insignificant. All of the key players in South African political decision making, whether senior politicians, military leaders, scientists, or influential academics, were all members of the AB. As such, it is fair to say that they were nationalistic and would have a common background/culture/view of the world.

Botha described the cabinet meeting process in an interview: “We had inherited the system of collegiate Cabinet government from the British. There was thus no official voting in Cabinet, but every minister had the right to express their point of view. In the end the chairperson sums up the debate and his opinion becomes the Cabinet decision. If Cabinet ministers still did not agree, the way was open to them to resign. There was no other way. In reality, the government's decision was the PM's decision in summarizing what he believed it should be.” Sue Onslow, “Former South African Foreign Minister RF ‘Pik’ Botha in an interview with Dr. Sue Onslow,” Pretoria, July 15, 2008, <http://sas-space.sas.ac.uk/5806/2/Pik_Botha_Transcript_Appendix_1.pdf>, p. 10. Armscor, the state arms procurement and production agency, was assigned responsibility for weapon design, production, delivery systems, and storage. The AEB would furnish the highly enriched uranium.

NOTE: An extremely detailed, recently declassified, 1978 US intelligence report on this second shaft (identified in the report as the “Kalahari drill site” with the first shaft labeled the “tower site”) remotely determined from satellite imagery (two photos were included) that the “best total-hole-depth estimate is 169 to 227 m.” That is impressive given the actual drilled depth was 216 meters.

40. Outside observers have termed South Africa's strategy of testing “catalytic deterrence,” or their “ace-in-the-hole.” See, on the former: Mitchell Reiss, Bridled Ambition: Why Countries Constrain their Nuclear Capabilities (Washington, DC: Woodrow Wilson Center Press, 1995); on the latter, see: Michele A. Flournoy, Kurt M. Campbell, “South Africa's Bomb: A Military Option,” Orbis 32 (Summer 1988), p. 401.

Peter Liberman corroborates Stumpf's claim that this three-phase strategy was initiated in April 1978, reporting that then-Defense Minster P.W. Botha approved a memorandum, drafted by Army Brigadier John Huyser, outlining these three incremental options (in which Huyser recommended “openly joining the nuclear club” that was described as the third phase). Liberman also says that this three-phase strategy was further refined in 1983 by a new Armscor policy working group headed by Dr. André Buys, then-general manager of the Circle facility, to include in the third phase three separate escalatory steps: 1) overt declaration and/or an underground nuclear test; 2) an atmospheric demonstration 1,000 kilometers off the South African coast; 3) the threat of use in a military theater for self-defense.

44. Waldo Stumpf never addressed the advanced development of ballistic missile and/or cruise missiles that they were beginning to undertake at the time the program was halted, although other principals later did. It clearly was related to strategic defense, which would eventually have enabled South Africa to threaten anyone, at any distance, with assured destruction. That capability seems to be the only rational explanation for the efforts underway at Advena New Laboratories, and would be the same strategy employed by the superpowers that had prevented major war between them since 1945. Additional research is also necessary to determine the veracity of the claim that up to thirty-nine RSA-2 ballistic missiles were to be built (with a total of thirty deployed throughout the country in five flights of six missiles and mobile launchers each; see note 27). Specifically, what kinds of warheads were intended for those missiles? If nuclear, that would call into serious question most of the former government's claims regarding the total number of nuclear weapons to be built and the ultimate purpose of those weapons.

In April 1998, immediately following the parliamentary elections that led to the Hindu nationalist party takeover of the government, the new Prime Minister Atal Bihari Vajpayee assured a visiting US delegation—led by then-Ambassador to the United Nations Bill Richardson—that no nuclear tests were planned.

83. According to Horton, initially, only about 35-100 personnel actually worked at the Circle building, but with the addition of Advena Central Laboratories, the number grew to about 300 total, about half of which were engaged directly in building weapons in 1989. See Horton, “Out of South Africa: Pretoria's Nuclear Weapons Experience,” p. 12. Waldo Stumpf reported that the total number of personnel involved over the fifteen-year history never exceeded “1,000 individuals” and no more than 250 at any given time. See Stumpf, p. 6.
84. In late 1978, when the CIA first detected a military presence at the Valindaba uranium enrichment plant, the only explanation suggested was that South Africa must have progressed to producing weapon-usable uranium for which military protection was then necessary. The two suspected reasons were: 1) for the purpose of indigenously supplying fuel to the SAFARI-1 research reactor, or 2) “possible stockpiling of highly enriched uranium for military use, as part of a long-term effort to establish a nuclear weapons option.” National Foreign Assessment Center, “Scientific Intelligence Weekly Review,” April 30, 1979, <www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB181/sa20.pdf>.
85. Reiss, Bridled Ambition, p. 51. Note that neither South Africa nor Brazil was an NPT signatory at the time, but now both are NPT signatories. And that is a principal difference between the South African case and that of nuclear weapon threshold states today, because South Africa did not accede to the NPT until after it had abandoned its program, and hence was not legally prohibited from seeking to acquire nuclear weapons. The focus of US policy toward South Africa during the period of weaponization was primarily to apply intense diplomatic and economic pressure to force South Africa to simply accede to the NPT. With respect to nations of contemporary concern, e.g., Iran and Syria, which are already signatories (North Korea had been a signatory for a few years before withdrawing), US (and international) nonproliferation policy focus is to simply have them keep their commitments as specified in the treaty.
