Navigating The Storm: Iran-Iraq Tensions After ISIS's Fall

The intricate dance of power and influence in the Middle East has rarely been straightforward, and the relationship between Iran and Iraq stands as a testament to this complexity. While the world watched in horror as ISIS carved out its brutal caliphate, an unlikely, albeit unacknowledged, alliance formed. Both Iran and the United States found themselves fighting on the same side in the 2016 offensive to retake Mosul from ISIS, a shared enemy momentarily overshadowing decades of animosity. Yet, as the dust settled on the battlefield and ISIS's territorial control waned, the underlying currents of rivalry and strategic competition resurfaced, leading to persistent and evolving Iran and Iraq tension following ISIS's defeat.

This article delves into the multifaceted dynamics that define the post-ISIS relationship between Tehran and Baghdad. From the initial military cooperation against a common foe to the re-emergence of deep-seated geopolitical rivalries, we will explore how Iran's strategic depth in Iraq has grown, the internal and external pressures shaping Iraq's sovereignty, and the dangerous interplay of regional and international actors that continue to fuel a volatile environment. Understanding these tensions is crucial for anyone seeking to grasp the future trajectory of stability in a region perpetually at the crossroads of conflict and cooperation.

The Unlikely Alliance: A Shared Foe in ISIS

The rise of ISIS in 2014 presented an existential threat to Iraq and a significant challenge to regional stability. As the militant group swept across vast swathes of Iraqi territory, including Mosul, an unexpected alignment of forces began to take shape. Despite their long-standing geopolitical rivalry, Iran and the United States found themselves with a common enemy. This shared threat led to an unspoken, yet undeniable, cooperation on the ground. In a 2016 offensive to take Mosul back from ISIS, the U.S. and Iran fought on the same side without ever publicly acknowledging it. This tactical convergence was a stark reminder of how immediate dangers can forge temporary alliances, even among adversaries. Beyond the battlefield, the cooperation extended to formal agreements. On 31 December 2014, defence ministers of Iran and Iraq signed a military pact to combat ISIS, underscoring the urgency of the threat and the necessity for coordinated action. Iran quickly began to provide military aid to counter the militant advance, offering crucial technical advisers to the Iraqi government and supplying weapons to the Kurdish Peshmerga forces. This direct support was instrumental in bolstering Iraq's beleaguered security forces and turning the tide against ISIS, demonstrating Iran's immediate and effective response to a crisis on its doorstep. The fight against ISIS, therefore, temporarily masked the deeper geopolitical fissures, but it also created new avenues for Iranian influence within Iraq.

Iraq's Geopolitical Crucible: Caught in the Middle

Iraq's geographical position has always been both a blessing and a curse. Nestled between regional powers like Iran, Saudi Arabia, Turkey, and Syria, Iraq is a developing democracy that perpetually faces pressure from outside its borders. This precarious location means that Baghdad often finds itself caught in the crosscurrents of regional rivalries, struggling to assert its sovereignty amidst competing foreign interests. The list of challenges it faces is extensive, ranging from internal political fragmentation to external interference. Beyond external pressures, the Iraqi government also faces ongoing tensions with Kurdish groups pressing for greater autonomy in the north following a failed independence referendum in October 2017. These internal divisions, coupled with the legacy of the ISIS conflict and the need for extensive reconstruction, make Iraq particularly vulnerable to external manipulation. While the defeat of ISIS offered a glimmer of hope for national unity and stability, it simultaneously opened the door for various regional actors, particularly Iran, to solidify their influence, further complicating Iraq's journey towards true self-determination. The country's stability is inextricably linked to its ability to navigate these complex internal and external pressures, a task made even more challenging by the persistent Iran and Iraq tension following ISIS's decline.

The Deepening Rift: Iran's Growing Influence in Iraq

With ISIS largely defeated, the strategic landscape in Iraq shifted dramatically, paving the way for Iran to consolidate and expand its influence. Iran's engagement during the anti-ISIS campaign, providing critical military and advisory support when Iraq's conventional forces were faltering, earned it significant goodwill and leverage. This was particularly evident through the rise of various Iraqi militias, many of which serve Iran's interests and now control parts of Iraq. These Popular Mobilization Units (PMUs), initially formed to combat ISIS, have become powerful non-state actors, deeply integrated into Iraq's security apparatus yet often operating beyond direct government control. Thus, during periods of heightened tensions between Iran and the US, these militias are frequently used to enforce Iran’s policies, acting as proxies to project Iranian power and deter perceived threats. This dynamic creates a significant challenge for the Iraqi government, which struggles to assert its authority over armed groups that are simultaneously vital for security and a conduit for foreign influence. Beyond military and political leverage, Iran's influence is also deeply rooted in economic ties. Alongside Turkey and China, Iran is one of Iraq’s three largest trade partners. In 2021, Iraq was the world’s leading importer of Iranian goods, estimated at nearly $9 billion, about half of which comprises vital gas imports. This economic interdependence, particularly Iraq's reliance on Iranian energy, gives Tehran substantial sway over Baghdad, complicating any attempts by Iraq to distance itself from its powerful neighbor.

External Triggers: US and Israeli Actions Fueling Tensions

The delicate balance of power in Iraq is frequently disrupted by external actions, particularly those involving the United States and Israel, which directly impact the Iran and Iraq tension following ISIS. The US, backed by Saudi Arabia, has historically responded to hostility from Tehran’s government following the Islamic Revolution. This rivalry has manifested in various forms, including direct military actions. The air strikes, which hit four sites in Iraq and three in Syria, marked the first time the US has targeted Iran’s powerful Qods Force since the outbreak of the war between Israel and Hamas. Such actions, often presented as retaliatory or pre-emptive, inevitably escalate regional tensions and put Iraq in a precarious position as a battleground for proxy conflicts. Further complicating the situation, tensions in Iraq have grown in the wake of the Israeli attack on Iran on June 13. These incidents highlight how Iraq, despite its efforts to remain neutral, becomes a theatre for broader regional conflicts. The US continues to weigh the option of heading back into a war in the Middle East, with experts outlining various ways such an attack could play out, including the targeting of Iran’s ballistic missile arsenal and the killing of top military leaders. As concerns rose overnight about Iran's nuclear program and its non-compliance with nonproliferation obligations, as censured by a U.N. watchdog, the potential for a wider conflict involving the US and Iran directly or indirectly through Iraq remains a constant threat, jeopardizing Iraq's hard-won stability.

The Shadow War: Proxies and Escalation

The strategy of using proxies has become a defining feature of the regional power struggle, with Iraq often bearing the brunt of this shadow war. Iran's network of militias within Iraq serves as a potent tool for projecting power and responding to perceived threats without direct state-on-state confrontation. These groups, while ostensibly part of Iraq's security apparatus, frequently act in alignment with Iranian interests, launching attacks on US forces or other targets deemed hostile to Tehran. This has led to dangerous escalations, such as the airstrike that killed Iranian Gen. Qassem Soleimani, a move that brought the region to the brink of a wider conflict. The Iraqi government finds itself in an unenviable position, attempting to rein in these powerful non-state actors. For instance, the Iraqi government has sent security forces to Nineveh governorate to prevent the area from being used by militias to launch rockets, underscoring Baghdad's struggle to assert control over its own territory. In addition, several drones launched by Iran have been reported, further demonstrating the direct and indirect ways in which Iran projects its power within Iraq's borders. This constant state of low-intensity conflict, fueled by proxy actions and external interventions, perpetuates instability and makes any long-term resolution of the Iran and Iraq tension following ISIS incredibly challenging.

Historical Echoes: Shifting Alliances and Rivalries

To fully grasp the current Iran-Iraq dynamic, one must consider the historical context of regional rivalries and shifting alliances. This rivalry intensified in the early 2000s, when Syria actively supported insurgent groups in Iraq following the 2003 U.S. invasion, a stance that exacerbated tensions (Mansour & Thompson, 2020). For years, this created a political rift between Iraq and Syria, with Damascus often seen as undermining Baghdad's post-Saddam stability. However, over time, the situation shifted. Iraq, particularly following the rise of Iranian influence after the US withdrawal and the fight against ISIS, began to support the Syrian regime. This alignment cemented Syria with Tehran, forging a powerful axis that had previously been fractured. This historical evolution demonstrates how regional power dynamics are fluid, with former adversaries becoming allies, and vice versa, often driven by the pursuit of strategic interests and the emergence of new threats or opportunities. The current alignment, with Iraq increasingly drawn into Iran's orbit, is a direct consequence of these historical shifts and the power vacuum created by the weakening of traditional regional orders.

Economic Interdependence vs. Political Friction

The economic relationship between Iran and Iraq presents a fascinating paradox: deep interdependence coexisting with significant political friction. As noted, Iraq is Iran's largest trade partner, importing nearly $9 billion worth of Iranian goods in 2021. About half of this trade is comprised of gas imports, which are crucial for Iraq's electricity generation and industrial needs. This reliance on Iranian energy creates a powerful economic leverage point for Tehran, making it difficult for Baghdad to fully align with US sanctions or to distance itself from Iranian influence. This economic reality often clashes with Iraq's aspirations for greater sovereignty and its desire to balance relations with various international partners, including the United States and Saudi Arabia. While economic ties provide a degree of stability and mutual benefit, they also bind Iraq to Iran in ways that limit its foreign policy options. The challenge for Iraq lies in diversifying its energy sources and trade partners to reduce this dependency, a long-term goal that is difficult to achieve in the short term. The intricate web of economic ties ensures that even as political and security tensions flare, the fundamental connection between the two nations remains, adding another layer of complexity to the ongoing Iran and Iraq tension following ISIS.

The Quest for Regional Security: A New Middle East Order?

The post-ISIS era has reignited discussions about a "revisionism for the security architecture of the Middle East." This concept often includes calls for eliminating US military influence in the region following ISIS's defeat and a re-evaluation of regional alliances, including positions on Israel. Iran, a key proponent of such a revision, seeks to establish a security framework that is less dependent on external powers and more aligned with its own strategic interests, often through a network of allies and proxies. This vision directly clashes with the interests of other regional players and the US, which seeks to maintain its presence and influence to counter Iranian expansionism. Iran's nuclear program, with its declared intention to activate a third nuclear enrichment facility shortly after a U.N. watchdog censured Iran for failing to comply with nonproliferation obligations, adds another layer of complexity and risk to this quest for a new regional order. The potential for a nuclear-armed Iran significantly alters the security calculus for all actors, including Iraq, which would find itself on the front lines of any resulting escalation.

Iraq's Sovereignty on the Line

At the heart of the ongoing regional power struggles is the fundamental question of Iraq's sovereignty. As a developing democracy situated in a highly volatile neighborhood, Iraq constantly struggles to assert its independence against the competing influences of Iran, the US, Saudi Arabia, and Turkey. The presence of foreign troops, the operations of Iran-backed militias, and the economic pressures from its neighbors all chip away at Baghdad's ability to make truly independent decisions. The challenge for Iraq is not merely to survive but to thrive as a sovereign nation capable of charting its own course. This requires a delicate balancing act, engaging with all regional and international actors while safeguarding its national interests. The continued Iran and Iraq tension following ISIS makes this task immensely difficult, as Iraq often finds itself caught between the demands of its powerful neighbors and the aspirations of its own people for stability and self-determination.

The Path Forward: Navigating a Volatile Future

The complex web of relationships and rivalries in the Middle East, particularly the evolving dynamic between Iran and Iraq in the aftermath of ISIS, presents a formidable challenge for regional stability. What began as an unlikely, unacknowledged alliance against a common enemy has reverted to a more traditional, yet intensified, rivalry. Iran's deepened influence through military aid, economic ties, and proxy militias, coupled with external pressures from the US and Israel, ensures that the Iran and Iraq tension following ISIS remains a critical flashpoint. Iraq's precarious geopolitical position, caught between powerful neighbors and internal divisions, means it will continue to be a primary theatre for these broader regional struggles.

The Role of International Actors

The stability of Iraq, and by extension the wider Middle East, hinges significantly on the constructive engagement of international actors. The United States, Saudi Arabia, Turkey, and China all have vested interests in Iraq, ranging from security concerns to economic opportunities. A concerted international effort is required to support Iraq's sovereignty, strengthen its institutions, and help it diversify its strategic partnerships. This means moving beyond a zero-sum game approach and fostering an environment where Iraq can emerge as a stable, independent nation capable of managing its own affairs without undue foreign interference.

Implications for Regional Stability

The continued tension between Iran and Iraq, and the broader regional competition it reflects, carries significant implications for the entire Middle East. It fuels proxy conflicts, exacerbates sectarian divisions, and hinders economic development. The risk of wider conflict, whether through miscalculation or deliberate escalation, remains ever-present. Ultimately, achieving lasting peace and stability in Iraq requires not only addressing the immediate security threats but also fostering genuine dialogue and cooperation among regional powers, moving beyond historical grievances to build a more secure and prosperous future for all.

Conclusion

The journey from a shared fight against ISIS to the current state of heightened Iran and Iraq tension following ISIS is a microcosm of the Middle East's enduring complexities. While the defeat of the caliphate was a monumental achievement, it unveiled a new phase of geopolitical competition, with Iraq at its epicenter. Iran's strategic depth in Iraq, cemented through economic ties and the influence of powerful militias, continues to shape Baghdad's domestic and foreign policy. Simultaneously, external interventions and the broader US-Iran-Israel rivalry ensure that Iraq remains a volatile battleground. Understanding these intricate layers is vital for anyone seeking to comprehend the future of the region. The path forward for Iraq is fraught with challenges, demanding astute diplomacy, robust institution-building, and a delicate balancing act between powerful neighbors.
