Iran Nuclear, Biological, Chemical, and Missile Weapons …
Iran has been a party to the since 1970, and has an advanced nuclear program that was the subject of international negotiations and from 2002 until implementation of a comprehensive nuclear deal, the Joint Comprehensive Plan of Action (JCPOA) began in 2016. The United States unilaterally withdrew from the JCPOA on 8 May 2018, leaving its future in doubt.
Iran is not a member of the , and is actively working to acquire, develop, and deploy a broad range of and capabilities. The scope and status of Iran's and activities are unknown, but the most recent Western intelligence estimates have downgraded the likelihood that Iran maintains significant offensive chemical and biological weapons programs.
Mohamed Reza Shah initiated Iran's nuclear program during the 1950s with assistance from the U.S. Program. Establishing the Atomic Energy Organization of Iran (AEOI) in 1974, the Shah had ambitious plans to construct 20 nuclear power , a facility, and a plant for . [1] However, after the 1979 Iranian Revolution deposed the Shah, Ayatollah Khomeini deemed the nuclear program "un-Islamic" and ordered it terminated. In 1984, Khomeini reversed course on the issue of and sought international partners to continue building the Bushehr reactors. [2] Currently, Iran has complete nuclear fuel cycle capabilities including mining, milling, conversion, and enrichment facilities. [3] Iran's extensive enrichment program, which could be used to produce for a nuclear weapon, has been particularly controversial. At its 2015 peak, the program comprised nearly 20,000 gas centrifuges at 3 major facilities. [4]
The Board of Governors found Iran in non-compliance with its Comprehensive Safeguards Agreement in 2005, and the passed seven resolutions demanding that Iran halt its enrichment and reprocessing activities. Beginning in 2002, Iran, the IAEA, and various groupings of world powersfirst with France, Germany, and the United Kingdom (the EU-3), and later accompanied by China, Russia, and the United States (the )made numerous attempts to negotiate a settlement to the dispute. [5] Negotiations between the P5+1 and Iran yielded the Joint Comprehensive Plan of Action (JCPOA) in July 2015, a comprehensive 25-year nuclear agreement limiting Iran's nuclear capacity in exchange for sanctions relief. On 16 January 2016, all nuclear-related sanctions on Iran were lifted in response to its progress meeting key metrics of the deal. [6]
U.S. President Donald Trump campaigned on a promise to "dismantle the deal with Iran," however, the Administration initially upheld the deal. [7] On 8 May 2018, President Trump officially withdrew the United States from the JCPOA and announced the imminent re-imposition of all nuclear-related sanctions. He alleged that the deal was defective at its core, citing Iranian support for terrorism and pursuit of ballistic missiles (despite the fact these are not material to the terms of the JCPOA), as well as a presentation by Israeli Prime Minister Benjamin Netanyahu alleging that Iran had concealed details of its early-2000s nuclear weapons efforts from the international community. [8] Notably, President Trump did not claim that Iran had violated any specific terms of the agreement. Iran has expressed a willingness to remain in the JCPOA despite the U.S. withdrawal, and all other P5+1 states reiterated their commitment to full implementation of the deal. [9]
There is very little publicly available information to determine whether Iran has bought biological weapons. Iran acceded to the in 1929 and the in 1973. However, the U.S. government has accused Iran in the past of pursuing a biological weapons program. More recent U.S. intelligence estimates do not suggest that such a program currently exists. In its most recent unclassified report to Congress on the subject the U.S. Director of National Intelligence assessed that Iran "probably has the capability to produce some biological warfare (BW) agents for offensive purposes, if it made the decision to do so. [] Iran continues to expand its biotechnology infrastructure and seek technologies that could be used for BW." [10] This qualified assessment likely indicates that U.S intelligence does not have conclusive evidence of a current Iranian BW program. Historically, Iran has denied the acquisition or production of biological weapons.
Iran suffered severe losses from Iraq's use of chemical weapons between 1982 and 1988 during the Iran-Iraq War. Consequently, Iran has significant experience with the effects of chemical warfare (CW). Iran ratified the in November 1997 and has been an active participant in the work of the . Iran has publicly acknowledged the existence of a chemical weapons program developed during the latter stages of the 1980 to 1988 war with Iraq. After ratifying the CWC in 1997, Iran opened its facilities to international inspection and claimed that all its offensive CW activities had been terminated and the facilities destroyed prior to the treaty's .
Nevertheless, throughout the late 1990s and the early 2000s, the United States claimed that Iran maintained an active program for the development and production of chemical weapons. This program was alleged to include stockpiles of , , , and possibly , although U.S. intelligence agencies did not publicly provide evidence for these allegations. [11] Since 2003, the U.S. intelligence community has substantially downgraded its public assessments of Iranian chemical warfare capabilities. In its most recent unclassified report to Congress on the subject, the Director of National Intelligence asserted that Iran "maintains the capability to produce chemical warfare (CW) agents and conducts research that may have offensive applications." [12] Iran denies producing or possessing chemical weapons in violation of its treaty obligations.
Following the Iran-Iraq war, Iran committed itself to the development of one of the most sophisticated programs in the Middle East. Iran has pursued a dual-track strategy, developing both liquid and solid-fueled systems. [13] While Iran's program was initially dependent on foreign technical assistance, particularly from North Korea, Iran now likely has the indigenous capacity to develop, test, and build ballistic missiles. [14]
Iran's first ballistic missiles were Soviet -B and Scud-C models acquired from North Korea (renamed Shahab-1 and Shahab-2). [15] In 2003, Tehran deployed a medium-range ballistic missile (MRBM), the Shahab-3, which is a derivative of North Korea's Nodong missile. [16] Since 2004, Iran has test-fired numerous variants of the Shahab-3, which were designed to increase its range, payload, and accuracy, including the Ghadr-1 and the Emad. [17] In 2008, Iran successfully tested the Sejjil, a two-stage, solid fueled MRBM. [18]

In addition to its missile program, Iran possesses a space launch capability. Iran has successfully launched several satellites aboard its the Safir, with reports of an attempted launch from the new Simorgh SLV. Many have expressed concern over the dual- use capabilities of these systems and their potential application for . [19]
Iran is not a member of the or the Hague Code of Conduct against Ballistic Missile Proliferation. In 2015, to support implementation of the JCPOA, the UN Security Council adopted Resolution 2231, which called on Iran "not to undertake any activity related to ballistic missiles designed to be capable of delivering nuclear weapons." [20] The U.S., U.K., France, and Germany have claimed that Iran's subsequent ballistic missile tests were "inconsistent with" and "in defiance of" UNSCR 2231, with the U.S. imposing sanctions on Iran in response to its ballistic missile tests, most recently in 2017.
