Iraq-Iran War: A Devastating Conflict's Enduring Legacy

Dora Raynor III 23 Jun 2025

The Iraq and Iran War, often referred to as the First Persian Gulf War, stands as one of the 20th century's longest and most brutal conventional conflicts. Spanning nearly eight years from 1980 to 1988, this devastating confrontation reshaped the geopolitical landscape of the Middle East, leaving an indelible mark on millions of lives and setting the stage for future regional dynamics. It was a war born from a complex tapestry of historical grievances, deep-seated ethnic tensions, and profound political upheavals, particularly in the wake of the transformative Iranian Revolution of 1979.

This article aims to provide a comprehensive Iraq and Iran War summary, delving into its origins, the brutal nature of the fighting, the immense human cost, and its far-reaching legacy. We will explore how this pivotal historical conflict contributed to the proliferation of weapons of mass destruction, influenced international relations, and continues to cast a long shadow over the region, connecting historical events to present-day complexities involving Iran and its neighbors.

The Seeds of Conflict: A Troubled History

To truly understand the Iraq and Iran War, one must look beyond the immediate catalyst and examine the deep historical roots that fueled the animosity between these two nations. Iran, a middle eastern nation bordered by Turkey and Iraq to the west, Pakistan, Afghanistan and Turkmenistan to the east, the Caspian Sea to the north and the Persian Gulf to the south, has long shared a complex and often contentious relationship with its western neighbor, Iraq. Centuries of shifting borders, religious differences (Shia-majority Iran versus Sunni-led Iraq under Saddam Hussein), and competing regional ambitions laid a volatile groundwork.

The immediate trigger for the war, however, was a confluence of major political changes in the region. Relations with Iran had grown increasingly strained after the Shah was overthrown in 1979, culminating in the Iranian Revolution. This seismic event established a theocratic government under Ayatollah Ruhollah Khomeini, the spiritual leader of the Iranian revolution. Khomeini, a staunch anti-imperialist, proclaimed his policy of exporting the Islamic Revolution, which deeply unnerved neighboring Arab states, particularly Iraq, which had a significant Shia population. Iraq recognized Iran’s new Shiʿi Islamic government, but the Iranian leaders would have nothing to do with the Baʿath regime, which they denounced as secular. This ideological clash, coupled with long-standing border disputes, particularly over the Shatt al-Arab waterway (Arvand Rud in Iran), created an explosive atmosphere.

The Iraqi Invasion: The War Begins

Active hostilities began with the Iraqi invasion of Iran on 22 September 1980. Saddam Hussein, then President of Iraq, saw an opportunity in the post-revolutionary chaos in Iran. He believed Iran's military was weakened and disorganized by purges and internal strife, making it vulnerable to a swift Iraqi victory. His objectives were multi-faceted: to assert Iraq's dominance in the Persian Gulf, gain full control over the Shatt al-Arab, and perhaps even annex the oil-rich Iranian province of Khuzestan, home to a significant Arab population. Furthermore, it began when Iraq invaded Iran on 22 September 1980, after a long history of border disputes and after Iran demanded the overthrow of Saddam Hussein's regime. The Iraqi leadership viewed Khomeini's revolutionary rhetoric as a direct threat to its own secular Ba'athist rule and regional stability.

Saddam's initial calculations proved disastrously wrong. While Iraq made some early territorial gains, the Iranian forces, despite their disarray, rallied with fierce determination. Driven by revolutionary fervor and a deep sense of national defense, Iranian volunteers, including the newly formed Islamic Revolutionary Guard Corps (IRGC), joined the regular army in repelling the invasion. What Saddam envisioned as a quick, decisive victory soon devolved into a grinding war of attrition, marking the beginning of a prolonged and devastating conflict that would define the next eight years.

The Brutal Stalemate: Years of Attrition

Following the initial Iraqi advances, the Iraq and Iran War quickly descended into a brutal stalemate characterized by trench warfare, human wave attacks, and the widespread use of chemical weapons. Both sides dug in, transforming the front lines into a landscape reminiscent of World War I. The conflict became a test of endurance, with neither side able to achieve a decisive breakthrough, yet neither willing to concede defeat. Cities on both sides, particularly those near the border, suffered relentless bombardment, and oil facilities became prime targets in the "Tanker War" in the Persian Gulf, drawing international concern.

The Human Cost of the Iraq and Iran War

Discover the human cost and cultural impact of this pivotal historical conflict. The scale of human suffering during the Iraq and Iran War was immense, truly staggering. Estimated killed and wounded during the war range from one to two million. This horrific toll includes not only combatants but also countless civilians caught in the crossfire, subjected to aerial bombings, and displaced from their homes. The war also left a generation of veterans on both sides with severe physical and psychological scars, grappling with the trauma of combat, chemical weapon exposure, and the loss of comrades. Families were torn apart, communities shattered, and the social fabric of both nations bore the deep wounds of prolonged conflict. The cultural impact was equally profound, shaping national narratives, art, and literature for decades to come, often focusing on themes of sacrifice, martyrdom, and resilience.

Weapons of Mass Destruction Concerns

One of the most chilling aspects of the Iraq and Iran War was the widespread and documented use of chemical weapons by Iraq against Iranian troops and civilians, particularly in the later stages of the conflict. This horrific practice, a violation of international law, highlighted the desperate measures taken by Saddam Hussein's regime to gain an advantage. The incredibly deadly and destructive nature of the conflict left a long legacy, including the proliferation in the development of weapons of mass destruction in Iraq and Iran. While Iraq openly used chemical agents, the war also spurred both nations to explore and develop their own WMD capabilities, driven by a perceived need for deterrence and national security in a hostile region. This legacy continues to be a source of international concern, particularly regarding Iran's nuclear ambitions, with accusations from nations like Israel that Israel accused Iran of crossing the nuclear threshold.

International Reactions and Interventions

The Iraq and Iran War did not occur in a vacuum. Its strategic location and the vital importance of Persian Gulf oil ensured significant international attention, though often with a complex and contradictory response. Many international powers, including the United States and several Arab states, covertly or overtly supported Iraq, viewing revolutionary Iran as a greater threat to regional stability and their own interests. This support often included intelligence, financial aid, and even military hardware, despite Iraq's use of chemical weapons. Conversely, Iran, isolated by its revolutionary ideology, found itself largely without major international allies, relying heavily on its own resources and the unwavering resolve of its populace.

The United Nations, throughout the conflict, attempted to mediate and bring about a ceasefire. Numerous Security Council resolutions were passed, calling for an end to hostilities, but for years, these appeals went unheeded. The war continued to rage, fueled by a deep-seated animosity and the unwillingness of either side to accept anything less than total victory or significant concessions from the other.

The Road to Resolution 598

After nearly eight years of brutal fighting, the war finally began to draw to a close with the acceptance of United Nations Security Council Resolution 598 by both sides. This resolution, adopted in July 1987, called for an immediate ceasefire, withdrawal of forces to international borders, and negotiations for a comprehensive peace settlement. However, its acceptance was not immediate or straightforward, particularly for Iran.

Iran's Initial Stance on Reparations

Initially, Iraq agreed to these conditions, but Iran would not unless Iraq paid war reparations. Iran, having suffered immense damage and human loss due to the Iraqi invasion, felt morally and legally entitled to compensation for the aggression. For years, Iran insisted on the removal of Saddam Hussein and the payment of reparations as preconditions for peace, viewing Iraq as the aggressor. This stance, while understandable from Iran's perspective, prolonged the conflict as Iraq steadfastly refused to pay, and the international community was reluctant to enforce such a condition, fearing further destabilization.

The Final Push and Iran's Acceptance

The turning point came in 1988. After years of a costly stalemate, Iraq, emboldened by international support and a renewed offensive capability, began launching several successive attacks into Iran. These offensives, combined with the devastating "War of the Cities" (missile attacks on civilian centers) and the accidental shooting down of Iran Air Flight 655 by a U.S. warship, severely weakened Iran's military and economic capacity. Facing mounting casualties, economic ruin, and increasing isolation, and potentially putting an end to the stalemate, Iran agreed to the resolution and put an end to the war. Ayatollah Khomeini famously described his decision to accept the ceasefire as "drinking the chalice of poison," a testament to the profound difficulty and bitterness of ending a war that had demanded so much sacrifice from his nation.

The Lingering Legacy of the Iraq and Iran War

The Iraq and Iran War summary would be incomplete without examining its enduring legacy. The incredibly deadly and destructive nature of the conflict left a long legacy, including the proliferation in the development of weapons of mass destruction in Iraq and Iran. This arms race mentality, born from the war's existential threat, continues to shape regional security concerns today. The war also solidified the revolutionary government in Iran, albeit at a tremendous cost, and reinforced its anti-Western stance, viewing international interventions during the war as biased against it.

For Iraq, the war, though ending without a clear victory, was portrayed by Saddam Hussein as a triumph against Iranian aggression, bolstering his image domestically. However, the immense debt incurred to finance the war, primarily from Kuwait and Saudi Arabia, would later become a significant factor in Saddam's decision to invade Kuwait in 1990, setting the stage for the First Gulf War and subsequent conflicts. The human cost, as previously mentioned, continues to haunt both nations, with millions of lives lost or forever altered, and societies grappling with the trauma of a generation defined by conflict.

Echoes in Modern Geopolitics: Iran's Regional Influence

The historical Iraq and Iran War summary provides crucial context for understanding contemporary Middle Eastern geopolitics. The war deeply influenced Iran's strategic thinking, fostering a doctrine of self-reliance and the development of asymmetric warfare capabilities. This includes a robust missile program and the cultivation of regional proxy forces, which Iran views as essential for projecting power and deterring potential adversaries. The experience of the war, where Iran felt abandoned by the international community, reinforced its determination to build an independent security apparatus.

Proxy Conflicts and Regional Tensions

Today, the legacy of the war can be seen in the ongoing power struggles across the region. Fighting intensified across multiple proxy fronts—Hezbollah in Lebanon, Houthis in Yemen, and militias in Syria/Iraq. These groups, often supported or influenced by Iran, are key players in conflicts that reflect a broader regional rivalry, often with Saudi Arabia and its allies. The historical animosity between Iran and its Arab neighbors, exacerbated by the Iraq and Iran War, continues to manifest in these proxy conflicts, which destabilize nations and contribute to humanitarian crises. The recent tensions, such as when Iran fired 200 ballistic missiles at Israel, and reports like "A woman carries her child following the Israeli strikes on Iran, in Tehran, Iran, June 15, 202
