Iran has chemical and biological weapons arsenal
State department reports consistently list Iran as one of the states expected to be developing an offensive biological weapons program. During the 8-year long Iran-Iraq war, Iraq used chemical weapons against Iranian soldiers and it is expected that Iran has developed both chemical and biological weapons to be able to respond in kind to future attacks.

The U.S. Intelligence Community believes Iran probably has an offensive biological weapons program but lacks clear intelligence proving that this is the case. The U.S. Intelligence Community stated in its November 2004 721 Report: “Tehran probably maintains an offensive BW program. Iran continued to seek dual-use biotechnical materials, equipment, and expertise. While such materials had legitimate uses, Iran's biological warfare program also could have benefited from them. It is likely that Iran has capabilities to produce small quantities of BW agents, but has a limited ability to weaponize them."

Although it does not have unequivocal evidence, the U.S. Intelligence Community believes Iran has an offensive chemical weapons research and development capability. The Intelligence Community reported in its November 2004 unclassified Report to Congress on the Acquisition of Technology Relating to Weapons of Mass Destruction and Advanced Conventional Munitions, also known as the 721 Report, that Iran “…continued to seek production technology, training, and expertise from foreign entities that could further Tehran's efforts to achieve an indigenous capability to produce nerve agents. Iran may have already stockpiled blister, blood, choking, and possibly nerve agents and the bombs and artillery shells to deliver them-which it previously had manufactured.”
Similar uncertainties surround Iran’s possible current work on a biological weapons program, which the nation also denies, Cordesman said in a separate draft report (see GSN, Sept. 7, 2005).“The world market in biotechnology, food processing, pharmaceutical, and other related equipment has grown so large, has so many dual-use items, and has such weak controls, that it is impossible to know what Iran has purchased and is purchasing, and from whom they are purchasing such items from,” the report states, noting that Iran has purchased such equipment from countries across Europe and Asia.“What is clear is that Iran has become a country with a relatively advanced base in biotechnology, which has extensive laboratory and research capability, and steadily improving industrial facilities with dual-use production capabilities with all of the equipment necessary to produce wet and dry storable biological weapons.”While the spread of biological weapon agents is often unpredictable, Iran “should be able to deploy weapons with at least the lethality that militarized anthrax had reached during the Cold War,
Iran’s growing industrial and medical capabilities could enable the country to produce chemical or biological weapons if it chose to do so, security expert Anthony Cordesman said in two draft reports released this month.“Iran‘s technology base is advanced enough … so that Iran retains some capability to make chemical weapons, and it may have inactive or mothballed facilities. While there have been no public reports of active production, this is possible and such efforts can occur at low levels and be easy to conceal,” Cordesman, an analyst for the Center for Strategic and International Studies, wrote in a draft report on Iran’s potential chemical-weapon capabilities.Iran was subjected to chemical weapons strikes during its war with Iraq in the 1980s and rejects claims that it today possesses such a capability itself.U.S. intelligence officials and other sources continue to assert the existence of an active Iranian chemical weapons program, but “Iran‘s current status as a chemical weapons power is simply impossible to determine,” the report states.
On Iran, which is a BWC member state, the State Department said: "Available information indicates Iran has remained engaged in dual-use BW-related activities. The United States notes that Iran may not have ended activities prohibited by the BWC, although available information does not conclusively indicate that Iran is currently conducting activities prohibited by the convention."
A 2001 State Department report found that "based on available evidence, Iran has an offensive biological weapons program" and that the nation was "capable of producing at least rudimentary biological warheads for a variety of delivery systems, including missiles." The department's 2005 document bolstered that conclusion.
Nuclear weapons aren’t the only concern. Iran is capable of producing chemical weapons of mass destruction, and also of weaponizing them via delivery systems, according to a report from the U.S. deputy director of national intelligence for analysis. Also according to the report, “Iran probably has the capability to produce some biological warfare (BW) agents for offensive purposes. . . . Iran continues to seek dual-use technologies that could be used for BW.” A 2005 report by the U.S. State Department concluded that “Iran is in violation of its CWC [Chemical Weapons Convention] obligations because Iran is acting to retain and modernize key elements of its CW [chemical weapon] infrastructure to include an offensive CW R&D capability and dispersed mobilization facilities”; it also found that “Iran has an offensive biological weapons program in violation of the BWC [Biological Weapons Convention].” Even the Obama administration, typically eager to promote and praise multilateral arms-control agreements, does not conclude that Iran is in compliance with either of these treaties.

The United States and many of its allies consider a nuclear-armed Iran an intolerable threat to stability in a volatile region and to security around the world. Failure to keep Iran from acquiring nuclear weapons, they argue, could have a range of negative consequences, including sparking a nuclear arms race in the Middle East and threatening the existence of Israel. Yet in their struggle to thwart Iran's nuclear ambitions, the United States, its allies, and like-minded members of the international community should not focus only on the dire consequences of failure in this mission. They should also consider the implications of success. Smothering Iran's prized nuclear program could well provoke dangerous reactions, including, perhaps, Iran's pursuit of other types of unconventional weapons systems. In one possible scenario, an Iran deprived of nuclear weapons is driven to develop a capability already within its technical grasp: biological weaponry. Whether manifested as the initiation of a new biological warfare program or the intensification of an existing (but so far unconfirmed) biological weapons effort, the Iranian threat is grave enough to warrant serious consideration of a rigorous biological nonproliferation strategy that could be implemented in parallel with nuclear nonproliferation efforts.

Of course, some argue that Iran has already demonstrated biological weapons ambitions. Indeed, Iran was suspected of initiating offensive biological work in the 1980s during the Iran-Iraq War (Nuclear Threat Initiative, 2011a), and media sources in the late 1990s documented efforts by Tehran to recruit former Soviet bioweaponeers (Miller and Broad, 1998). Accounts of an Iranian biological weapons program in the past or present, however, have not been proved. This uncertainty should come as no surprise given the many factors that can shroud external knowledge of foreign biological weapons programs, which can readily be disguised or hidden within a country's peaceful biological research networkÑas occurred infamously in the Soviet Union, where, in the early 1990s, it was discovered that behind the Iron Curtain a massive offensive biological weapons enterprise had employed some 65,000 scientists working in dozens of facilities throughout the country (Nuclear Threat Initiative, 2011b).

While Iran's strategic thinking and intent with regard to biological weapons are difficult to assess from the outside, its technological capabilities are more vulnerable to external assessment and provide important information on Iran's threat potential.1 Iran possesses the scientific infrastructure and knowledge base necessary for a biological weapons program. Specifically, Iran's advanced pharmaceutical and biotechnological industries present what is known as a dual-use risk: The same materials, equipment, and expertise used for the development and production of legitimate biological products can also be employed for illicit weapons activities (US Department of State, 2005). Indeed, with its longstanding ventures in vaccine development and production and its growing expertise in cutting-edge biotechnologies, including genetic engineering, Iran boasts one of the developing world's most advanced life science industries (Nuclear Threat Initiative, 2011a; Westerdahl et al., 2003).

Beyond these enabling conditions, US government agencies have assessed that Iran also possesses the more specific know-how critical for mature weapons development -- namely, the capability to produce and weaponize biological agents, as well as technologies for their delivery. For example, a 2005 report by the US Department of State concluded, "Iran is technically capable of producing at least rudimentary, bulk-fill biological warheads for a variety of delivery systems, including missiles" (US Department of State, 2005: 20). In 2006, the Office of the Director of National Intelligence (ODNI) reported to Congress that Iran "probably has the capability to produce large-quantities of some Biological Warfare agents for offensive purposes, if it made the decision to do so" (Office of the Director of National Intelligence, 2008: 4). The 2009 ODNI report reiterated this concern but omitted the descriptor "large quantities" from its assessment (Office of the Director of National Intelligence, 2009: 5).
