What Happened to Iran-Iraq War?

The Iran-Iraq War, also known as the First Gulf War, was a protracted and brutal conflict that lasted nearly eight years, from September 22, 1980, to August 20, 1988. The war's origins were multifaceted, rooted in a complex mix of historical border disputes, particularly over the Shatt al-Arab waterway, and deep ideological and political animosities. Iraqi President Saddam Hussein sought to capitalize on the perceived weakness and internal instability of revolutionary Iran following the 1979 Islamic Revolution, aiming to assert Iraq's dominance in the Persian Gulf and prevent the export of Iran's revolutionary ideology to Iraq's Shia majority.

The conflict unfolded in several phases. Initially, Iraqi forces made significant advances into Iranian territory, but Iran, despite its post-revolutionary disarray, quickly mobilized and launched successful counter-offensives by mid-1982, pushing Iraqi forces back to pre-war borders. The war then devolved into a grinding war of attrition, characterized by large-scale trench warfare, human wave attacks by Iran, and Iraq's widespread use of chemical weapons, including against its own Kurdish population in Halabja in 1988. The 'Tanker War' and 'War of the Cities,' involving attacks on shipping in the Persian Gulf and missile strikes on urban centers, further escalated the conflict and drew international attention.

The war concluded in August 1988 when Iran, exhausted and facing renewed Iraqi offensives and chemical attacks, accepted United Nations Security Council Resolution 598, which called for a ceasefire. The formal peace agreement, including troop withdrawals and the resumption of diplomatic relations, was not signed until August 16, 1990. The human cost was staggering, with estimates of total casualties ranging from 1 million to 2 million, and approximately 500,000 killed on both sides, with Iran suffering greater losses. The war also caused immense economic damage, estimated to exceed one trillion dollars.

As of March 2026, the legacy of the Iran-Iraq War continues to influence regional dynamics. Efforts to account for missing persons remain ongoing, with Iraq and Iran periodically exchanging the remains of soldiers. For instance, in February 2026, Iraq received six remains while handing over 79 (41 unidentified) to Iran, and Iran held a ceremony in Khorramshahr to receive 85 sets of remains recovered from border areas. Over 50,000 soldiers from the war are still considered missing. Diplomatic and economic cooperation between Iran and Iraq has seen a rapprochement since 2003, with agreements signed in September and October 2025 to enhance border security, facilitate trade, and manage cross-border movement. However, Iran continues to demand reparations for the damages caused by the war, a position reiterated by Iranian President Masoud Pezeshkian and Foreign Minister Abbas Araghchi in March 2026, linking it to broader demands for security guarantees amidst the ongoing '2026 Iran War' (a separate conflict involving the US and Israel). This demonstrates how the unresolved issues and profound scars of the Iran-Iraq War remain a potent factor in the complex geopolitical landscape of the Middle East.
