Iran–Iraq War

The Iran–Iraq War was a massive conflict between two neighboring nations.

It lasted for eight years, from September 1980 to August 1988. This war is considered the deadliest conventional war ever fought between the regular armies of developing countries. Approximately 500,000 people died during the fighting.

The war began when Iraq invaded Iran. It ended when both sides accepted a ceasefire brokered by the United Nations. This peace deal was known as United Nations Security Council Resolution 598.

Several complex political and territorial issues caused the war.

First, there was a long history of border disputes. Iraq wanted to reclaim the eastern bank of the Shatt al-Arab river. This was land Iraq had ceded to Iran in the 1975 Algiers Agreement. Second, the Iraqi government had political fears. Iraq was led by President Saddam Hussein and a Sunni Muslim-controlled Ba'athist government. Iran had recently undergone the 1979 Iranian Revolution. Iran's new leader was Ruhollah Khomeini, who led a theocratic state of Shia Muslims. Iraq feared Khomeini would export his state ideology to Iraq. Iraq also worried that Iran would rally Iraq's own Shia majority against the government.

Iraq also had goals regarding regional power. Saddam Hussein wanted to replace Egypt as the leader of the Arab world. He sought hegemony, or total dominance, over the Persian Gulf. Iraq saw an opportunity because Iran appeared weak after its revolution. The Iranian military suffered from severe officer purges. Between February and September 1979, the Iranian government executed 85 senior generals. By the start of the war, about 12,000 officers had been purged from the army. This left the Iranian military in a much weaker state than before.

Consequently, Iraq believed it could achieve a decisive victory.

The war moved through several distinct military stages.

At first, Iraq launched a surprise airstrike against Iranian air force infrastructure. They then began the main invasion in September 1980. Iraq expected a quick win, but the invasion stalled by December 1980. The Iranian military then gained momentum and recaptured all its territory by June 1982. After pushing Iraqi forces back to the original borders, Iran launched an invasion into Iraq. This started a five-year offensive that led to a military stalemate. This stalemate involved large-scale trench warfare and deliberate attacks on civilians.

Both nations relied on different international allies to support their efforts. Iraq was aided by the United States, the United Kingdom, and the Soviet Union. Other supporters included France, Italy, Yugoslavia, and most Arab countries. Iran received aid from various other nations. These included Syria, Libya, North Korea, China, and South Yemen. Pakistan, Cuba, and Israel also provided aid to Iran. The conflict became a major event involving many global powers. This international involvement helped shape how the war was fought over the eight years.

At the end of the conflict, the results were largely inconclusive.

The war did not create any permanent changes to the borders. Neither country received war reparations to pay for the destruction. Both sides suffered massive financial losses during the fighting. The military stalemate was finally broken in mid-1988 by Iraqi counter-offensives. However, the peace was fragile. Low-level military conflicts continued for a long time. Relations only truly improved after Saddam Hussein was overthrown in 2003.

The Iran–Iraq War serves as a significant example of how regional tensions can escalate into global issues. It demonstrates how internal political changes, like a revolution, can impact international security. The war also shows the impact of military purges on a nation's ability to defend itself. The heavy use of chemical attacks and the targeting of civilians remain dark parts of this history. Despite the high cost in lives and money, the territorial status quo remained unchanged. This highlights how long and difficult modern conventional warfare can be for all involved.
