Biological

Japan had an active biological weapons (BW) program prior to 1945. The focal point was the now infamous Unit 731 based at a laboratory complex in northeastern China during the Japanese occupation. Unit 731 experimented on Chinese civilians and Allied prisoners of war with various biological agents, including plague, cholera, and hemorrhagic fever. After World War II, the Japanese government abandoned its BW program. Japan signed the BWC in 1972 and ratified it in 1982. Japan has actively supported negotiation of a protocol to strengthen current BWC provisions. Since the 1995 Aum Shinrikyo's sarin attack and failed attempt to disperse anthrax, Japan has increased its focus on bio-terrorism defenses. Although Japan has a growing biotechnology industry, it is still small in comparison to its chemical industry. As a member of the Australia Group, Japan's biotech industry is subject to a comprehensive set of export controls.

South Africa’s biological weapons program was one of the two principal components of its covert state-sponsored CBW program, codenamed Project Coast (later Project Jota). Personnel associated with Coast have characterized it as the most sophisticated program of its type outside of the former Soviet Union, but international CBW experts generally consider it to have been considerably less advanced from a scientific standpoint. Although ostensibly created entirely for defensive purposes, since government and Cuban military forces in Angola were reportedly equipped for and planning to use—if not already using—CW agents against the South African Defence Force (SADF), from the outset the program also had offensive features and capabilities. The apartheid-era South African government viewed itself as the target of a “total onslaught†by Soviet-backed Marxist guerrillas or regimes in neighboring states and black nationalists at home, and to meet this all-encompassing “red-black danger†it was apparently willing to use almost any means at its disposal to defend itself. It was in this highly charged political and military context, which precipitated a “bunker†or “laager†mentality, that Coast was secretly initiated in 1981 under the aegis of the SADF Special Forces. The chief facility for researching, producing, and testing BW agents and lethal toxic chemicals was a military front company called Roodeplaat Research Laboratories, located north of Pretoria, and other facilities were established to develop protective clothing and manufacture exotic assassination devices. Project Officer Dr. Wouter Basson also set up an elaborate network of procurement and financial front companies overseas. During its existence Coast scientists tested or developed a wide range of harmful BW agents, including Bacillus anthracis, botulinum toxin, Vibrio cholerae, Clostridium perfringens, plague bacteria, and salmonella bacteria. Some of these pathogens were probably used to assassinate individual “enemies of the state,†and it is alleged that both anthrax bacteria and V. cholerae were each employed on at least one occasion to infect larger populations. The CBW program was officially dismantled in 1993, in the midst of a liberalizing transformation of the regime. There are indications, however, that certain personnel who were intimately involved in the program, including Basson, may have provided technical knowledge, equipment, or materials to “rogue regimes†such as Libya, to foreign intelligence personnel, to unscrupulous black marketers trafficking in dangerous weapons, and perhaps also—if certain journalists can be believed—to elements of a shadowy international network of right-wing extremists. These claims have yet to be fully investigated, much less verified. The extent to which various foreign governments, military establishments, and intelligence agencies secretly monitored or covertly assisted in the development of the program likewise remains an open question.

Chemical
|
Japanese scientists began developing chemical weapons (CW) as early as 1917. The Japanese Army used CW after invading China in 1937, conducting an estimated 1,000 to 3,000 attacks. Japan reportedly produced five to seven million munitions containing agents such as phosgene, mustard, lewisite, hydrogen cyanide, and diphenyl cyanarsine. Although Japanese forces used many of these munitions between 1937 and 1945, a considerable amount was abandoned when Japanese forces retreated. After World War II, Japan pledged to not produce CW and participated in the negotiations for the CWC, which Japan signed in 1993 and ratified in 1995. Japan's CWC obligations include the responsibility for the disposal of abandoned CW (ACW) in China. The deadline for completion of the clean-up is 2007, but the scale of the program has led many to estimate that Japan will need an extension. Japan's chemical industry is the world's second largest, with about 16 percent of global chemical production. As a member of the Australia Group, Japan has developed comprehensive and well-enforced export controls on chemical weapons precursors and dual-use items. Since the 1995 Aum Shinrikyo sarin attack, Japanese spending on CW defense has increased.

The chief facility for researching and producing CW agents was a military front company called Delta G Scientific, located between Johannesburg and Pretoria, and several other facilities were set up to develop protective clothing, manufacture exotic assassination devices, and “weaponize†irritants (Riot Control Agents such as CS and CR) and incapacitants by placing them in artillery shells, mortar bombs, and grenades. Project Officer Dr. Wouter Basson also set up an elaborate network of procurement and financial front companies overseas. During its existence Coast scientists tested and developed both small quantities of well-known CW agents (including mustard agent, sarin, tabun, BZ, and perhaps VX) and a host of lethal, hard-to-trace toxic chemicals. Several of these latter, above all the toxic organophosphates, were almost certainly employed to assassinate individual “enemies of the state.†Certain CW facilities also carried out research on the suitability of using illegal drugs such as methaqualone (“Quaaludesâ€), MDMA (“Ecstasyâ€), LSD, marijuana extract (tetrahydrocannibol), and cocaine as incapacitating “calmatives,†but some of these illegal drugs may have ended up being sold for a profit. The CBW program was officially dismantled in 1993, in the midst of a liberalizing transformation of the regime. There are indications, however, that certain personnel who were intimately involved in the program, including Basson, may have provided technical knowledge, equipment, or materials to “rogue regimes†such as Libya, to foreign intelligence personnel, to unscrupulous black marketers trafficking in dangerous weapons, and perhaps also—if certain journalists can be believed—to elements of a shadowy international network of right-wing extremists.

Missile
|
Japan does not have a ballistic missile development program, but its space program includes a number of technologies that could potentially be adapted to long-range missiles. The solid-fueled M-5 rocket system, first launched in 1995, includes technologies that could be adapted to develop intercontinental ballistic missile (ICBM) capabilities roughly similar to those of the U.S. MX Peacekeeper missile. Japan's two-stage H-2 rocket is capable of placing a two-ton payload into orbit, but the H-2 is not optimal for ballistic missile applications due to its reliance on cryogenic liquid hydrogen and oxygen fuel. Japan lacks sophisticated command and control systems, as well as some guidance and warhead technology that would be necessary to develop operational missiles. Japan has partnered with the United States to research ballistic missile defenses (BMD), but has yet to make a final decision on future development and deployment. Many in Japan argue that a missile defense system would compliment the U.S. nuclear deterrent and defend against possible belligerents such as North Korea. Others argue that the system's costs outweigh the benefits, especially since the system's effectiveness is unproven. Missile defense also raises potential legal issues regarding Japanese legislation barring the military use of space. Japan is an active member of the MTCR and was involved in drafting the International Code of Conduct Against Ballistic Missile Proliferation (ICOC).

It is not clear when South Africa began ballistic missile-related efforts, but reportedly by the mid-1980s, some missile infrastructure existed in the country. It appears that Israel collaborated with South Africa in development of this program, but the nature and extent of this relationship is unknown. Following a July 1989 flight-test of what Pretoria described as a “booster rocket†in a space-launch program, U.S. intelligence noted striking similarities between this system and Israel’s intermediate-range Jericho-2 ballistic missile. Facing U.S. opposition to missile proliferation and the end of its apartheid government, South Africa abandoned its missile and space launch programs in 1991 and dismantled associated facilities under international observation. South Africa became a member of the Missile Technology Control Regime (MTCR) in 1995.

Nuclear
|
Japan's "Atomic Energy Basic Law" allows only peaceful nuclear activities, and its "Three Non-Nuclear Principles" pledge that Japan will not possess, produce, or permit the introduction of nuclear weapons into the country. Despite Japan's long-standing stance against nuclear weapons, there was an internal debate in the early 1970s about whether Japan should sign the NPT, in part due to concerns about assuring access to nuclear technology to meet national energy needs, and the discriminatory nature of the treaty. Some conservatives were also concerned that closing off the nuclear option might negatively impact future national security needs. Japan has played an active role in nuclear nonproliferation and disarmament, and has proposed a process for the total elimination of nuclear weapons. Japan ratified the CTBT in 1997 and has been a strong supporter of a Fissile Material Cut-off Treaty (FMCT). However, Japan's security relationship with the United States has tempered Tokyo's emphasis on disarmament. For example, Japan remains quiet about the possible presence of nuclear warheads on U.S. ships and military bases in Japan. Japan increasingly relies on nuclear power for its electricity needs, and has a highly developed civilian nuclear sector. Japan has a controversial program for recycling spent nuclear fuel that has produced large quantities of plutonium in the form of metal-oxide nuclear fuel. At the end of 2001, Japan had more than 30 metric tons of spent fuel stored at reprocessing plants in Britain and France, along with a domestic stockpile of 5 to 6 tons. These nuclear fuel stockpiles will ultimately return to Japan for use in domestic nuclear facilities. The original plan called for consumption of the stored fuel by 2010, but due to technical and safety issues, this timetable has been delayed and return of the stored fuel to Japan is proceeding slowly. Some argue this material could provide Japan with a latent nuclear weapons capability. In addition, the new facility under constructing in Rokkasho (Aomori Prefecture) will increase Japanese domestic reprocessing capacity and potentially produce an additional 5 tons of metal-oxide nuclear fuel per year. Although anti-nuclear sentiment among the Japanese public has far outweighed support for keeping a nuclear option open, several neighboring countries have expressed concerns about possible Japanese nuclear ambitions. Partly in response to these fears, the Japanese government completed an internal study in 1995 that reaffirmed previous conclusions that developing nuclear weapons would damage both Japan’s national security and regional security. However recent tension developing in the region, particularly in the Korean peninsula, has led to increased discussions in Japan about the once taboo subject of nuclear weapons development. Despite recent speculation that Japan may reconsider its nuclear options, the deep aversion to nuclear weapons among the Japanese public will likely make any move in this direction difficult.

In the 1960s, South Africa began to explore the technical utility of "peaceful nuclear explosions" for mining and engineering purposes. In 1973, then Prime Minister Johannes Vorster approved a program to develop a limited nuclear deterrent capability. Ultimately, South Africa manufactured six air-deliverable nuclear weapons of the "gun-type" design. In parallel with decisions to end apartheid, the government halted the bomb program in 1989 and dismantled existing weapons and associated production equipment. South Africa acceded to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a non-nuclear weapon state in 1991, and International Atomic Energy Agency (IAEA) inspectors subsequently verified the completeness of its nuclear dismantlement. South Africa joined the Zangger Committee in 1994 and the Nuclear Suppliers Group in 1995. South Africa was instrumental in winning indefinite extension of the NPT in 1995, and played a leading role in successful conclusion of the 2000 NPT Review Conference as a member of the "New Agenda Coalition" that also included Brazil, Egypt, Ireland, Mexico, New Zealand, and Sweden. More recently, South Africa began working more closely with the IAEA in 2004, in order to monitor international smuggling of nuclear weapons materials, after investigations of a South African businessman exposed connections to the A.Q. Khan network. In 2004, there was also ample discussion concerning South Africa’s dwindling coal reserves and its need for additional nuclear power generation.

Overview
|
Japan's 1947 constitution, which renounces the right to use force or the threat of force as a means of settling international disputes, sets important limits on Japanese security policy. Japan does not have any weapons of mass destruction (WMD) programs, although it has the technical capability to produce basic nuclear weapons and missiles in a relatively short time. The Japanese government is highly active in the international nonproliferation and disarmament arena, and party to all relevant multilateral treaties and regimes. As the only country to have suffered a nuclear weapons attack, Japan has been especially active in the field of nuclear nonproliferation and arms control. Japan ratified the Nuclear Non-Proliferation Treaty (NPT) in 1976 and the Comprehensive Test Ban Treaty (CTBT) in 1997. Before 1945, Japan developed and employed both chemical and biological weapons. Japan is now a state party to both the Chemical Weapons Convention (CWC) and the Biological and Toxin Weapons Convention (BWC). Japan is also a member of the Australia Group, the Nuclear Suppliers Group, the Missile Technology Control Regime (MTCR), and the Zangger Committee. Japan has an active nuclear energy program, one of the world's leading chemical industries, a growing biotechnology sector, and an active commercial space program.

South Africa's nuclear, biological, chemical, and missile programs reflected perceptions of internal and external threats stemming from its former government's policy of apartheid, as well as the country's advanced state of technical development. Pretoria developed nuclear weapons and ballistic missiles but relinquished these armaments in the early 1990s. The apartheid government also undertook a chemical and biological weapons (CBW) defense program, which reportedly also included offensive research and use of CBW agents against opponents of that government. While the proliferation legacies of South Africa's nuclear and missile programs were effectively resolved through verified disarmament measures that won international acclaim, dismantlement of the country's CBW capabilities was not verified to a comparable degree of certainty. The post-apartheid government of South Africa implemented its nonproliferation and disarmament policy through the Non-Proliferation of Weapons of Mass Destruction Act (No. 87 of 1993) to control the transfer of sensitive items and technologies. South Africa is the first and, to date, only country to build a nuclear arsenal, and then voluntarily dismantle its entire nuclear weapons program. The South African experience demonstrates that at least under some conditions, unilateral disarmament is not only possible, but can improve a nation’s security.
