The Genesis of Conflict: Iran-Iraq War and Regional Ambitions

The Iran-Iraq War, which erupted in September 1980, was a culmination of long-standing border disputes, ideological differences, and a fierce regional power struggle. For decades, the Shatt al-Arab waterway, a vital strategic artery, had been a point of contention between the two nations. However, the immediate catalyst for the invasion was the seismic shift in Iran following the 1979 Islamic Revolution. The overthrow of the pro-Western Shah Mohammad Reza Pahlavi and the establishment of an Islamic Republic under Ayatollah Ruhollah Khomeini sent shockwaves across the Middle East. Iraq, under the leadership of Saddam Hussein, saw this period of Iranian internal turmoil as a golden opportunity. The new revolutionary government in Tehran was perceived as weak and distracted, grappling with internal reforms and the aftermath of the hostage crisis with the United States. This perceived vulnerability fueled Saddam's ambitions. **Iraq also wished to replace Iran as the power player in the Persian Gulf, which was not seen as an achievable objective prior to the Islamic Revolution because of Pahlavi Iran's economic and military superiority as well as its close relationships with the United States and Israel.** With Iran seemingly preoccupied, **while Iran was distracted dealing with the Americans and trying to introduce its Islamic reforms, Saddam Hussein decided to invade Iran.** He aimed to seize the disputed territories, secure dominance over the Gulf, and perhaps even topple the nascent Islamic regime, which he viewed as a threat to his secular Ba'athist rule and a potential instigator of Shi'ite unrest within Iraq. This aggressive move ignited a conflict that would last for eight devastating years, fundamentally altering the geopolitical landscape and drawing in external powers, including the US.

US Policy Shifts: From Neutrality to Covert Support

The United States' approach to the Iran-Iraq War was characterized by a complex evolution, driven by shifting geopolitical priorities and the desire to maintain a delicate balance of power in the oil-rich Persian Gulf. Initially, Washington sought to remain neutral, but as the war progressed, its stance began to tilt significantly.

Initial Stance: Strict Neutrality

When the war broke out, the United States was still reeling from the Iranian hostage crisis, which had severely strained relations between Washington and Tehran. **After the hostage crisis, the U.S.** was wary of any direct entanglement in the region, especially given the revolutionary fervor in Iran. Consequently, **initially, Reagan continued the policy he inherited from Jimmy Carter of practicing strict neutrality in the conflict.** This policy aimed to avoid taking sides in a conflict that was seen as primarily a regional affair, and to prevent either belligerent from gaining overwhelming dominance that could destabilize global oil supplies. The memory of the hostage crisis meant that any overt support for Iran was unthinkable, while support for Iraq, then a Soviet-aligned state, was also problematic.

The Pivot to Baghdad

However, this neutrality proved to be short-lived. As Iran's revolutionary forces gained momentum and began to push back Iraqi invaders, threatening to turn the tide of the war and potentially export its revolution across the region, Washington's concerns mounted. An Iranian victory was perceived as a greater threat to regional stability and U.S. interests than an Iraqi one. The prospect of a powerful, revolutionary Iran dominating the Gulf was deeply unsettling to the U.S. and its regional allies. **By 1982, however, the government in Washington began to shift toward a position of supporting Iraq.** This shift was covert at first, involving the sharing of intelligence and later, more direct assistance. The U.S. provided Iraq with satellite imagery, economic aid, and even dual-use technology that could be repurposed for military use, all while publicly maintaining a facade of neutrality.

The Iran-Contra Affair: Covert Arms for Influence

Adding another layer of complexity and controversy to the US involvement was the Iran-Contra affair. This clandestine operation revealed the extent of the Reagan administration's willingness to engage in secret dealings to achieve its foreign policy objectives. **The main tool by which U.S. policy makers sought to secure their position in Iran in 1985 and 1986 was secretly providing arms and intelligence information.** This was done in exchange for the release of American hostages held by Hezbollah in Lebanon and to fund the Contra rebels in Nicaragua, circumventing a congressional ban. This dual-track policy, simultaneously supporting Iraq while secretly attempting to engage with elements within Iran, underscored the convoluted and often contradictory nature of US foreign policy during this turbulent period. The scandal, when it broke, severely damaged the credibility of the Reagan administration and highlighted the dangers of opaque foreign policy initiatives.

The Unspoken Horrors: Chemical Weapons and Disillusionment

One of the darkest chapters of the Iran-Iraq War was Iraq's extensive use of chemical weapons, particularly against Iranian soldiers and civilians, and even against its own Kurdish population in Halabja. These atrocities, which constituted war crimes, were met with a disturbing silence from the international community, including the United States. **Without any international outcry in the wake of Iraq’s use of chemical weapons, Iran was left disillusioned and even more distrusting of the U.S.** This lack of condemnation from Washington, despite its knowledge of Iraq's chemical warfare program, reinforced Iran's perception that the U.S. was actively hostile towards it and willing to overlook egregious human rights violations to achieve its strategic aims. The failure to condemn or act against Iraq's use of chemical weapons had profound and lasting consequences. It not only deepened Iran's sense of betrayal and isolation but also set a dangerous precedent, signaling that such actions might go unpunished. This historical wound continues to fester in Iranian memory, contributing to a deep-seated distrust of Western powers and influencing its strategic calculations in the decades that followed. The silence on chemical weapons use is a critical element in understanding the enduring animosity and lack of trust that characterizes the relationship between the United States and Iran.

Post-War Dynamics and Shifting Alliances

The end of the Iran-Iraq War in 1988 did not bring an immediate era of peace and stability to the region. Instead, it reshaped alliances and laid the groundwork for future conflicts. Iraq, despite being supported by the U.S. during the war, quickly became a pariah state after its invasion of Kuwait in 1990, leading to the First Gulf War. This swift reversal of fortunes for Saddam Hussein's regime demonstrated the fluid nature of international relations. Meanwhile, the global geopolitical landscape was also undergoing a monumental transformation. **Later in the 20th century, the USA and the Soviet Union worked towards an end to their Cold War.** The collapse of the Soviet Union fundamentally altered the bipolar world order, leaving the United States as the sole superpower. This new unipolar moment presented both opportunities and challenges for U.S. foreign policy in the Middle East. With the Soviet counterweight removed, the U.S. found itself with greater freedom of action but also greater responsibility for regional stability. Iran, emerging from its devastating war with Iraq, continued to view the U.S. with suspicion, especially given the legacy of American support for Saddam and the lack of condemnation for his chemical weapons use. The post-Cold War era saw the U.S. become more directly involved in Middle Eastern affairs, often leading to increased tensions with Iran.

September 11 and a Fleeting Opportunity for Cooperation

The horrific terrorist attacks of September 11, 2001, on American soil, unexpectedly created a brief window for potential cooperation between the United States and Iran, despite their long history of animosity and the complex legacy of the Iran-Iraq War and US involvement. **The September 11, 2001, terrorist attacks opened an unlikely opportunity for the United States and Iran to cooperate.** Both nations shared a common enemy in al-Qaeda and the Taliban regime in Afghanistan, which had harbored the terrorists. Remarkably, **the Islamic Republic was apparently never seriously considered to be behind the attacks and in fact was among the first governments to express public sympathy for the victims.** This shared grief and common threat initially fostered a degree of tacit cooperation in the early phases of the war in Afghanistan, with Iran providing intelligence and logistical support to the Northern Alliance, which was backed by the U.S. However, this fragile opportunity quickly dissipated. President George W. Bush's "Axis of Evil" speech in 2002, which grouped Iran with Iraq and North Korea, effectively extinguished any hopes for a sustained rapprochement, reinforcing Iran's distrust and pushing it further into isolation. The moment of potential collaboration, born from shared tragedy, was lost, perpetuating the cycle of mistrust and confrontation.

Iraq's Enduring Vulnerability: Caught in the Crossfire

Decades after the Iran-Iraq War, Iraq finds itself in a precarious position, often caught in the geopolitical crossfire between its powerful neighbors and external actors, particularly the United States and Iran. The legacy of past conflicts, including the Iran-Iraq War and US involvement, continues to define its vulnerability. **As Israeli jets and Iranian rockets streak across the Middle Eastern skies, Iraq finds itself caught squarely in the crossfire.** Its geographical location, bordering both Iran and a region frequently targeted by Israeli strikes, makes it an unwilling battleground for proxy conflicts. This vulnerability is not lost on Washington. **Washington’s own tacit acknowledgement of Iraq’s vulnerable position** underscores the strategic challenges faced by both the U.S. and Iraq. The presence of various armed groups within Iraq, some with strong ties to Iran, further complicates the situation, creating a complex web of allegiances and rivalries. These groups, often referred to as "proxies," have become central to the regional power struggle, frequently clashing with U.S. forces stationed in Iraq, and contributing to the instability that plagues the nation. The echoes of the Iran-Iraq War, with its shifting alliances and external interventions, resonate strongly in contemporary Iraq, highlighting its ongoing struggle for sovereignty and stability.

Contemporary Tensions: Proxies, Strikes, and the Shadow of War

The shadow of the Iran-Iraq War and US involvement looms large over current Middle Eastern tensions, particularly the escalating confrontations between Iran, Israel, and the United States. The complex web of alliances and proxy forces established during and after the Iran-Iraq War continues to play a critical role in regional dynamics. Iranian-backed groups, such as the Popular Mobilization Forces (PMF) in Iraq, are a significant factor. **Members of the Popular Mobilisation Forces (PMF) carry images of comrades killed in US airstrikes in western Iraq in 2024**, a stark reminder of the ongoing clashes. **These groups have served both as a regional buffer and** as instruments of Iranian influence, extending Tehran's reach across Iraq, Yemen, and Syria. The potential for direct confrontation remains high. **Direct US involvement in the conflict could see Iran activate what remains of its proxies across Iraq, Yemen and Syria, which have previously launched attacks on American assets in the region.** This threat of proxy retaliation is a constant concern for U.S. policymakers. The recent flare-up between Iran and Israel has further heightened anxieties. While the U.S. publicly maintains a stance of non-involvement in Israel's specific actions, the lines are often blurred. **Trump appeared to indicate that the United States has been involved in the Israeli attack on Iran in June 17 social media posts where he said we have control of the skies and American made.** Such statements, even if ambiguous, fuel Iranian suspicions and contribute to the cycle of escalation. The U.S. government **has repeatedly denied involvement in Israel’s initial attack against Iran—a position that Iran has disputed as missiles continue to fly between the two countries and the risk of** wider conflict remains palpable. As the international community **weighs its future involvement in the conflict between Iran and Israel, many leaders are looking with fresh eyes at Iran’s activities targeting Americans worldwide over four** decades, including incidents stemming from the post-Iran-Iraq War period. The potential for a wider conflict involving direct U.S. military action is a grave concern. **President Donald Trump said he will allow two weeks for diplomacy to proceed before deciding whether to launch a strike in Iran.** This indicates the high stakes and the desire to avoid full-scale war, yet the threat remains. The implications of such a conflict are dire. **How would Iran handle direct United States involvement? Iran would not absorb American strikes without retaliating.** This understanding of Iranian strategic doctrine underscores the immense risks of escalation. Prominent figures like Bernie Sanders have voiced strong warnings against military intervention. **Bernie Sanders warned against US involvement in military action against Iran, noting Israeli Premier Benjamin Netanyahu's past support for the Iraq War as a cautionary example.** This historical reference serves as a stark reminder of the unintended consequences and protracted engagements that can arise from military action in the Middle East, echoing the complex legacy of the Iran-Iraq War and US involvement. The current tensions are a direct continuation of historical grievances and strategic maneuvers that have their roots in the conflicts of the past.

Lessons Learned: The Complex Legacy of US Engagement
