Through Volatility (chemistry), Morale and Soviet Union

The Iraqi chemical weapons program, which had been active since the 1970s, was aimed at regulated offensive use, as evidenced in the chemical attacks against Iraqi Kurds as part of the Anfal campaign in the late 1980s. The 1988 Halabja massacre in Iraqi Kurdistan, which killed at least 3,200 people, is considered one of the worst attacks of the war. The Iraqis had also utilized chemical weapons against Iranian hospitals and medical centres. According to a 2002 article in the American newspaper The Star-Ledger, 20,000 Iranian soldiers and combat medics were killed on the spot by nerve agents. As of 2002, 5,000 of the 80,000 survivors continue to seek regular medical treatment, while 1,000 are hospital inpatients.

Operationally, Iraqi forces transitioned from artillery attacks, to low-altitude bombing, to high-altitude bombing. Nerve agents, with a lower persistency, were used on Iranian frontlines, and dissipated in time to be safely overrun by Iraqi forces. Mustard gas with its higher persistency was used for area denial and attack the rear of the battlefield. Iraq exploited the high temperatures that made it difficult for Iranian troops to wear protective suits and masks for extended periods.

Strategically, by the end of the war Iraqi chemical warfare had crippled Iranian morale. The threat that Iraqi Scud ballistic missiles, used with conventional warheads in the conflict's war of the cities, would carry chemical weapons caused fleeing of Iranian urban areas. Alongside 1988 ground and naval defeats, this is considered one of the reasons Iran accepted the United Nations-brokered ceasefire in August.

Though the use of chemical weapons in international armed conflict was banned under the Geneva Protocol, much of the international community remained indifferent to the attacks; Iraq's military campaign in Iran was supported by the United States and the Soviet Union, both of whom had sought to contain Iranian influence after the Islamic Revolution of 1979. Despite this, following the first nerve agent use in the 1984 Battle of the Marshes, the United States condemned Iraqi chemical attacks and began formal discussions at the Conference on Disarmament on what would become the 1993 Chemical Weapons Convention, comprehensively outlawing chemical weapon production, stockpiling, and use.

Background

After the 1973 Arab–Israeli War, Iraq decided to improve all aspects of its army. Iraqi General Ra'ad al-Hamdani stated that, despite careful analysis of the 1973 Arab–Israeli War, no clear progress in the Iraqi army was achieved by the Ba'ath Party. In comparison to their Israeli counterparts, the Iraqi Army was faced with a significant deficit in technological expertise. In 1979, due to Saddam Hussein's policies as well as those of leading Ba'ath Party officials and senior military officers, the Iraqi Army underwent increasing politicization. There was a saying at the time, "better a good Ba'athist than a good soldier". During the early months of the Iran–Iraq War, Iraq attained successes because of Ba'ath Party interference and its attempts to improve the Iraqi Army, but the essential problem was that the military leaders did not have a clear strategy or operational aim for a war.

Reporter Michael Dobbs of the Washington Post stated that Reagan's administration was well aware that the materials sold to Iraq would be used to manufacture chemical weapons for use in the war against Iran. He stated that Iraq's use of chemical weapons was "hardly a secret, with the Iraqi military issuing this warning in February 1984: 'The invaders should know that for every harmful insect, there is an insecticide capable of annihilating it ... and Iraq possesses this annihilation insecticide.'" According to Reagan's foreign policy, every attempt to save Iraq was necessary and legal.

According to Iraqi documents, assistance in the development of chemical weapons was obtained from firms in many countries, including the United States, West Germany, the Netherlands, the United Kingdom, and France. A report stated that Dutch, Australian, Italian, French and both West and East German companies were involved in the export of raw materials to Iraqi chemical weapons factories.
