Iran-Iraq War / The Imposed War (1980-1988)

The Iran-Iraq War permanently altered the course of Iraqi history. It strained Iraqi political and social life, and led to severe economic dislocations. Viewed from a historical perspective, the outbreak of hostilities in 1980 was, in part, just another phase of the ancient Persian-Arab conflict that had been fueled by twentieth-century border disputes. Many observers, however, believe that Saddam Hussein's decision to invade Iran was a personal miscalculation based on ambition and a sense of vulnerability. Saddam Hussein, despite having made significant strides in forging an Iraqi nation-state, feared that Iran's new revolutionary leadership would threaten Iraq's delicate SunniShia balance and would exploit Iraq's geostrategic vulnerabilities--Iraq's minimal access to the Persian Gulf, for example. In this respect, Saddam Hussein's decision to invade Iran has historical precedent; the ancient rulers of Mesopotamia, fearing internal strife and foreign conquest, also engaged in frequent battles with the peoples of the highlands.

The Iran-Iraq War was multifaceted and included religious schisms, border disputes, and political differences. Conflicts contributing to the outbreak of hostilities ranged from centuries-old Sunni-versus-Shia and Arab-versus-Persian religious and ethnic disputes, to a personal animosity between Saddam Hussein and Ayatollah Khomeini. Above all, Iraq launched the war in an effort to consolidate its rising power in the Arab world and to replace Iran as the dominant Persian Gulf state. Phebe Marr, a noted analyst of Iraqi affairs, stated that "the war was more immediately the result of poor political judgement and miscalculation on the part of Saddam Hussein," and "the decision to invade, taken at a moment of Iranian weakness, was Saddam's".

Iraq claimed territories inhabited by Arabs (the Southwestern oil-producing province of Iran called Khouzestan), as well as Iraq's right over Shatt el-Arab (Arvandroud). Iraq and Iran had engaged in border clashes for many years and had revived the dormant Shatt al Arab waterway dispute in 1979. Iraq claimed the 200-kilometer channel up to the Iranian shore as its territory, while Iran insisted that the thalweg--a line running down the middle of the waterway--negotiated last in 1975, was the official border. The Iraqis, especially the Baath leadership, regarded the 1975 treaty as merely a truce, not a definitive settlement.

The Iraqis also perceived revolutionary Iran's Islamic agenda as threatening to their pan-Arabism. Khomeini, bitter over his expulsion from Iraq in 1977 after fifteen years in An Najaf, vowed to avenge Shia victims of Baathist repression. Baghdad became more confident, however, as it watched the once invincible Imperial Iranian Army disintegrate, as most of its highest ranking officers were executed. In Khuzestan (Arabistan to the Iraqis), Iraqi intelligence officers incited riots over labor disputes, and in the Kurdish region, a new rebellion caused the Khomeini government severe troubles.

As the Baathists planned their military campaign, they had every reason to be confident. Not only did the Iranians lack cohesive leadership, but the Iranian armed forces, according to Iraqi intelligence estimates, also lacked spare parts for their American-made equipment. Baghdad, on the other hand, possessed fully equipped and trained forces. Morale was running high. Against Iran's armed forces, including the Pasdaran (Revolutionary Guard) troops, led by religious mullahs with little or no military experience, the Iraqis could muster twelve complete mechanized divisions, equipped with the latest Soviet materiel. With the Iraqi military buildup in the late 1970s, Saddam Hussein had assembled an army of 190,000 men, augmented by 2,200 tanks and 450 aircraft.

In addition, the area across the Shatt al Arab posed no major obstacles, particularly for an army equipped with Soviet river-crossing equipment. Iraqi commanders correctly assumed that crossing sites on the Khardeh and Karun rivers were lightly defended against their mechanized armor divisions; moreover, Iraqi intelligence sources reported that Iranian forces in Khuzestan, which had formerly included two divisions distributed among Ahvaz, Dezful, and Abadan, now consisted of only a number of ill-equipped battalion-sized formations. Tehran was further disadvantaged because the area was controlled by the Regional 1st Corps headquartered at Bakhtaran (formerly Kermanshah), whereas operational control was directed from the capital. In the year following the shah's overthrow, only a handful of company-sized tank units had been operative, and the rest of the armored equipment had been poorly maintained.

For Iraqi planners, the only uncertainty was the fighting ability of the Iranian air force, equipped with some of the most sophisticated American-made aircraft. Despite the execution of key air force commanders and pilots, the Iranian air force had displayed its might during local riots and demonstrations. The air force was also active in the wake of the failed United States attempt to rescue American hostages in April 1980. This show of force had impressed Iraqi decision makers to such an extent that they decided to launch a massive preemptive air strike on Iranian air bases in an effort similar to the one that Israel employed during the June 1967 Arab-Israeli War.
