The Iran-Iraq War
Iraq's invasion of Iran on 22 September 1980, exploiting the Revolutionary Guards' inexperience and the diplomatic isolation of the Islamic Republic, opened eight years of attrition. Saddam calculated that Iran would collapse or negotiate within weeks; instead the war mobilised Iranian nationalism across the revolutionary-secular divide. By 1982 Iran had recaptured its territory and invaded Iraq, seeking Karbala and Basra; neither side could achieve a decisive breakthrough for six more years. Iraqi chemical weapons — confirmed by UN investigators in 1986 — targeted Iranian forces and Kurdish civilians (Halabja, March 1988: 3,200-5,000 dead). The US provided Iraq with intelligence, agricultural credits, and diplomatic cover; the Soviet Union sold arms to both sides. The UN ceasefire (UNSC 598, July 1987) was accepted by Iran in July 1988 only after Iranian losses, the accidental US downing of Iran Air 655, and US attacks on Iranian oil platforms made continuation unsustainable. The war left both countries exhausted: over a million dead, $240 billion spent, no territorial change. Iraq's $80 billion debt to Gulf states and its territorial dispute with Kuwait directly motivated the 1990 invasion — the Iran-Iraq War's most consequential indirect legacy.
