The Shadow of Prohibited Warfare: Chemical Weapons in the Iraq-Iran War

The Iran-Iraq War, a conflict born from historical grievances and territorial disputes, quickly escalated into a prolonged and devastating struggle. While conventional arms dominated the headlines, a far more insidious weapon was silently deployed: chemical agents. Both Iran (1929) and Iraq (1931) were parties to the 1925 Geneva Protocol, which explicitly prohibits "the use of asphyxiating, poisonous or other gases, and of all analogous liquids, materials or devices, as well as the use of bacteriological methods of warfare." Despite these international commitments, the war witnessed a shocking disregard for these fundamental humanitarian laws, particularly concerning the use of chemical weapons. The very existence of this protocol underscores the international community's early recognition of the barbarity of chemical warfare, a recognition tragically ignored during this conflict. The sheer scale and frequency of chemical attacks during the Iraq-Iran War set a grim precedent, demonstrating the vulnerability of international agreements in the face of desperate military objectives.

Iraq's Chemical Arsenal: A Calculated Offensive

Iraq's chemical weapons program, which had been active since the 1970s, was aimed at regulated offensive use. This was not a hastily assembled arsenal but a systematically developed capability designed to provide a strategic advantage. The most chilling evidence of this program's intent and deployment came not only against Iranian forces but also against Iraq's own Kurdish population. Chemical attacks against Iraqi Kurds as part of the Anfal campaign in the late 1980s served as a horrific testament to the regime's willingness to use these weapons against its own citizens, underscoring the extreme nature of its chemical warfare doctrine. The early stages of the war saw Iraq testing the waters, gradually escalating its chemical attacks. From the beginning of the war until the end of 1983, Iran reported only 600 chemical casualties. This relatively low number, compared to what was to come, might have been interpreted by Iraq as a sign of international indifference or a lack of effective counter-measures from Iran. This perceived impunity likely emboldened Baghdad, leading to a significant increase in the scale and frequency of chemical weapon deployment in the subsequent years.

Escalation and Casualties: The Early Years (1980-1983)

The initial phase of the Iraq-Iran War, though brutal, saw limited documented use of chemical weapons. As noted, Iranian reports indicated approximately 600 chemical casualties by the close of 1983. This period was characterized by conventional ground battles, with both sides suffering heavy losses. However, the seeds of chemical warfare had already been sown, with Iraq gradually building its capabilities and seemingly gauging international reactions. The relatively contained casualty figures from chemical attacks in these early years did not, unfortunately, signal an adherence to international law but rather a prelude to a far more devastating chapter. It was a period of clandestine development and tactical experimentation that would soon unleash unprecedented horror.

A Disturbing Trend: 1984 Onwards

The year 1984 marked a disturbing trend in the Iraq-Iran War. The trickle of chemical casualties turned into a flood. In February alone, Iran suffered 1,100 chemical casualties, a stark increase from the cumulative total of the previous three years. This dramatic surge signaled a clear shift in Iraq's strategy, demonstrating its increasing capabilities in chemical warfare and its boldness in using them. The types of agents used, primarily mustard gas and nerve agents like Tabun, became more potent and widespread. This escalation was arguably decisive in allowing Iraq to reclaim the upper hand in certain phases of the conflict, particularly when Iranian human-wave assaults threatened Iraqi lines. The lack of real international response to Iraqi use of chemical weapons probably signaled Iran's loss of the propaganda war, with a demoralizing effect on its forces and populace. The world's silence, or at least its muted condemnation, inadvertently created an environment where such atrocities could proliferate.

Iran's Response: The Decision to Retaliate in Kind

The relentless chemical attacks by Iraq put Iran in an agonizing position. Faced with a devastating weapon against which it initially had little defense, Iran’s decision to employ chemical weapons in response became a grim necessity in its eyes. Iran's chemical weapons (CW) program was launched during the Iran/Iraq War, a direct consequence of Iraq's sustained chemical assaults. While the scale and nature of Iran's program and its battlefield use have been subjects of lingering debate, evidence suggests that Iran employed its own chemical warfare against Iraq on a few occasions during the war as well. This retaliatory use, though often described as limited compared to Iraq's extensive deployment, underscored the desperate measures taken by a nation under chemical siege. The article focuses on the history of and lingering debate about Iran’s chemical weapons program and allegations of limited battlefield use, highlighting the complex moral and strategic dilemmas faced by a nation defending itself against a prohibited weapon. The very act of developing and using CW, even in response, illustrates the brutalizing nature of such conflicts and the erosion of international norms when one party violates them with impunity.

The Propaganda Battlefield: Beyond the Chemical Cloud

While the physical effects of chemical weapons were horrific, their psychological and propaganda impact was equally significant. The lack of real international response to Iraqi use of chemical weapons probably signaled Iran's loss of the propaganda war, with a demoralizing effect on its troops and population. When the world remained largely silent or offered only weak condemnations, it sent a message of tacit acceptance or, at best, indifference. This played directly into Iraq's hands, allowing it to continue its chemical campaign with little fear of meaningful repercussions. However, Iran did manage to score a major propaganda victory on at least one occasion. Iran thus obtained numerous 'Iraqi chemical weapons intact and scored a major propaganda victory by publicizing this evidence. This tangible proof of Iraq's chemical warfare program, showcased to the world, aimed to shame the international community into action and garner sympathy for Iran's plight. While this was probably a propaganda campaign, rather than a real military concern in terms of turning the tide of the war single-handedly, it served to highlight the moral bankruptcy of Iraq's tactics and to pressure international bodies to take a stronger stance. The discovery and exhibition of these intact weapons were a powerful visual indictment, forcing the world to confront the reality of what was happening on the battlefields of the Iraq-Iran War.

The Decisive Edge? Chemical Weapons and Strategic Outcomes

The strategic impact of chemical weapons in the Iraq-Iran War is a subject of intense debate among military historians. However, there is a strong argument that chemical weapons were arguably decisive in allowing Iraq to reclaim the upper hand, especially during critical junctures of the conflict. When Iranian human-wave attacks, fueled by revolutionary zeal, threatened to overwhelm Iraqi defenses, the deployment of chemical agents could break up formations, cause mass casualties, and create panic, effectively stalling or reversing Iranian advances. This tactical advantage, coupled with a weak international response, allowed Iraq to continue its use with relative impunity, thereby influencing the overall trajectory of the war. The resolution of the conflict, which ultimately ended in a stalemate, was undoubtedly shaped by the terrifying effectiveness of these prohibited weapons and the world's reluctance to intervene decisively against their use. From a global perspective, the use of CW by Iraq and allegedly by Iran demonstrated that third world weapons of mass destruction, even if rudimentary, posed a significant and destabilizing threat to regional and international security.

Human Cost: The Lingering Scars of Chemical Warfare

Beyond the strategic implications, the most profound and tragic legacy of chemical weapons in the Iraq-Iran War is the human cost. The casualty figures paint a grim picture of escalating suffering. Iran took 13,500 chemical casualties in 1987 alone, a significant increase compared to 11,100 in 1986. These numbers represent not just immediate deaths but also a vast population of survivors who suffered from long-term debilitating illnesses. Exposure to agents like mustard gas led to chronic respiratory problems, severe skin lesions, eye damage, and an increased risk of various cancers. Decades after the war, veterans and civilians exposed to these chemicals continue to battle the physical and psychological scars. Many suffer from chronic lung disease, severe burns, and psychological trauma that impacts their daily lives and the lives of their families. The medical infrastructure in Iran, in particular, has been strained by the ongoing need to care for these victims. Their stories serve as a powerful and enduring reminder of the indiscriminate and long-lasting brutality of chemical warfare, far beyond the immediate battlefield. The human element, the personal tragedies behind each casualty number, underscores the YMYL (Your Money or Your Life) implications of such weapons, affecting not just soldiers but entire communities and future generations.

International Condemnation and the Path to Prohibition

While the international response during the height of the Iraq-Iran War was criticized for its inadequacy, the global community did eventually react, albeit slowly. The UN Security Council issued statements condemning the use of chemical weapons during the conflict, though these condemnations often lacked the teeth to halt their deployment effectively. The revelations and evidence of widespread chemical attacks, particularly by Iraq, spurred renewed efforts to strengthen international prohibitions against these weapons. The devastating experience of the Iraq-Iran War, coupled with other instances of chemical weapon use, significantly contributed to the push for a more comprehensive and verifiable ban. This momentum culminated in the Chemical Weapons Convention (CWC), which prohibits the development, production, stockpiling, and use of chemical weapons and mandates their destruction. The CWC was opened for signature on 13 January 1993 and entered into force in 1997. Both Iran and Iraq later became parties to the CWC, committing to the complete elimination of their chemical arsenals under international verification. This landmark treaty represents a global consensus that chemical weapons are an abhorrent class of weapons that must never be used again, a lesson hard-won from the battlefields of the Iraq-Iran War.

Lessons Learned: Preventing Future Atrocities

The Iraq-Iran War serves as a stark and painful lesson in the history of chemical warfare. It demonstrated the devastating potential of these weapons when used on a large scale, the inadequacy of existing international frameworks at the time to prevent their deployment, and the long-term suffering inflicted upon victims. The experience underscored the urgent need for robust international monitoring, verification, and enforcement mechanisms to prevent future atrocities. The CWC, a direct response to such horrors, is a testament to the global commitment to eradicate chemical weapons. However, ongoing challenges, such as the proliferation of chemical weapons technology and the continued use of chemical agents by non-state actors or rogue regimes, remind us that the fight for a world free of these weapons is far from over. Vigilance, strong international cooperation, and unwavering adherence to humanitarian law remain paramount to prevent another dark chapter like the one witnessed during the Iraq-Iran War.

Conclusion: A Stark Reminder of War's Brutality

The Iraq-Iran War chemical weapons saga is a chilling testament to the depths of human cruelty and the devastating consequences of unchecked warfare. From Iraq's calculated offensive use, including against its own Kurdish population, to Iran's desperate retaliatory deployments, the conflict laid bare the horrific reality of prohibited weapons. The escalating casualties, the long-term suffering of survivors, and the initial, muted international response highlight a dark period in modern history. Yet, this grim chapter also spurred a stronger global resolve to outlaw these instruments of terror. The eventual establishment and widespread adoption of the Chemical Weapons Convention stand as a beacon of hope, a commitment forged in the crucible of immense suffering. As we reflect on the Iraq-Iran War, it serves as a powerful reminder of the imperative to uphold international law, ensure accountability for atrocities, and tirelessly work towards a world where chemical weapons are relegated solely to the history books.
