Iran needed the weapons after US arms sales were cutoff in the wake of the break in diplomatic relations. [[Iraq]] had invaded the majority [[Arab]] [[Khuzestan]] province in southwestern Iran in September 1980. The ensuing [[Iran-Iraq War]] lasted until 1988, when some naval operations by the [[United States]] against Iran impressed the impossibility of their position upon the Iranian leadership. Iran finally signed an armistice which ceded to Iraq the [[Shatt al-Arab]] waterway, the latter country's main war aim. Less than three years later, Iraq ceded it back to guarantee Iranian [[neutrality]] in the [[Gulf War]] against the United States. | Iran needed the weapons after US arms sales were cutoff in the wake of the break in diplomatic relations.
