The January 2020 Retaliation: Operation Martyr Soleimani

One of the most significant and widely reported instances where Iran attacks US base in Iraq occurred in early 2020. This event, officially named "Operation Martyr Soleimani" by Iran, was a direct and overt response to a preceding, highly provocative action by the United States. The meticulous planning and execution of this operation underscored Iran's capability and willingness to project power in retaliation for perceived aggressions.

The Preceding Assassination

The catalyst for Iran's retaliatory strike was the U.S. assassination of Iranian General Qassem Soleimani on January 3, 2020. General Soleimani, the commander of the Islamic Revolutionary Guard Corps' (IRGC) Quds Force, was a pivotal figure in Iran's regional military and political strategy. His killing in a drone strike near Baghdad International Airport was seen by Tehran as an act of war and a severe violation of its sovereignty and national dignity. The immediate aftermath was marked by widespread condemnation in Iran and vows of "severe revenge" from the country's leadership, setting the stage for an inevitable response.

The Ballistic Missile Barrage

True to its word, Iran struck back at the United States for the killing of its top general early Wednesday, January 8, 2020. In a coordinated assault, Iran carried out a ballistic missile attack on air bases housing US forces in Iraq. The primary targets were Al Asad Airbase in western Iraq and a base in Erbil, northern Iraq. Ballistic missiles fired by Iran caused explosions near the U.S. military facility, a clear demonstration of Iran's precision strike capabilities. Footage, reportedly of the missile attack, was shown on Iranian state TV, emphasizing the official nature and intent behind the operation.

The attack on Al Asad, in particular, was significant as it is one of the largest U.S. military installations in Iraq. Al Asad has been a target of strikes before, most notably in early 2020, when Iran launched a missile attack against the base in retaliation for the U.S. assassination of Iranian General Qassem Soleimani. While initial reports suggested no U.S. casualties, a number of U.S. military personnel were later confirmed to have suffered traumatic brain injuries, highlighting the serious nature of the attack despite the absence of immediate fatalities. This specific incident marked a dangerous escalation, pushing the two nations closer to a direct military conflict than at any point in recent history.

A Surge in Attacks: Post-October 2023 Dynamics

Beyond the high-profile 2020 incident, the frequency and intensity of attacks targeting U.S. forces in Iraq have seen a dramatic increase, particularly since October 7, 2023. This surge is deeply intertwined with the broader regional tensions stemming from the conflict in Gaza and the subsequent ripple effects across the Middle East. The dynamic where Iran attacks US base in Iraq has evolved, often involving proxy groups acting on Tehran's behalf, adding layers of complexity to the attribution and response.

The Islamic Resistance of Iraq's Role

Since October 7, 2023, the Islamic Resistance of Iraq, an umbrella group of Iran-backed Iraqi armed factions, has claimed responsibility for a significant number of these assaults. This group has carried out more than 180 such attacks against U.S. forces in Iraq, Syria, and Jordan. The sheer volume of these attacks underscores a concerted campaign to pressure the United States and its allies in the region. Between October 17 and January 29, there were more than 150 attacks on U.S. personnel in Iraq and Syria alone, indicating a sustained and aggressive posture by these groups.

The tactics employed by these factions often involve drones and rockets, aiming to inflict casualties or at least disrupt U.S. military operations. For instance, U.S. officials told Reuters that personnel were injured in an attack against a military base in Iraq on a recent Monday. Similarly, coalition forces were slightly injured in Iraq in a spate of drone attacks over a 24-hour period at U.S. bases in Iraq as regional tensions flared following the deadly explosion at a hospital in Gaza. The attack late Monday resembled previous ones carried out by Iraqi armed groups, backed by Iran, which have targeted the base repeatedly over the past nine months.

The Threat to Regional Stability

The most recent attack risks drawing U.S. forces into an offensive role in Israel's war with Iran, a dangerous prospect that could dramatically expand the scope of the conflict. Thus far, the U.S. has attempted only to provide defensive support for Israel in the conflict, carefully avoiding direct entanglement in an offensive capacity against Iran. However, the continuous targeting of U.S. personnel and facilities tests this resolve and increases the likelihood of a direct military response, which could further destabilize an already volatile region. Saturday's attack, for instance, appeared to be the largest of the more than 140 attacks on U.S. interests, signaling an increasing level of aggression and capability from the attacking groups.

These attacks also carry a significant psychological impact, keeping U.S. forces on high alert and demonstrating the persistent threat posed by Iran-aligned militias. The attacks slowed after three American troops were killed in a drone attack on a small U.S. outpost in Jordan, which prompted a U.S. retaliatory strike, illustrating the cycle of escalation and de-escalation that characterizes these interactions.

Targets and Tactics: US Bases Under Fire

When Iran attacks US base in Iraq, the choice of targets and the methods employed are often strategic, aiming to maximize impact while potentially avoiding full-scale war. The primary targets are typically military installations housing U.S. and coalition forces, such as Al Asad Airbase and the base in Erbil. These locations are critical hubs for U.S. operations in the region, making them symbolic and practical targets for groups seeking to challenge the American presence.

The tactics predominantly involve the use of rockets and unmanned aerial vehicles (UAVs), commonly known as drones. Rockets, while less precise, can still cause significant damage and disruption, particularly in mass salvos. Drones, on the other hand, offer greater precision and can be harder to detect, posing a persistent threat to personnel and infrastructure. The increasing sophistication of these drone attacks, as evidenced by incidents where American troops were killed, highlights the evolving nature of the threat and the continuous need for enhanced defensive measures.

The attackers often launch these projectiles from within Iraqi territory, complicating the U.S. response due to concerns about sovereignty and avoiding civilian casualties. This strategy leverages the complex political landscape within Iraq, where various armed groups operate with differing degrees of autonomy and allegiance, often blurring the lines of responsibility and making direct retaliation against Iran more difficult.

Casualties and Consequences: The Human Toll

While the focus often remains on geopolitical implications, the direct consequence of these attacks is the human toll on military personnel. A number of U.S. military personnel have been injured in missile and drone attacks on airbases in western and northern Iraq. These injuries range from physical wounds to traumatic brain injuries (TBIs), which can have long-lasting effects on service members. The cumulative impact of these injuries, even if not immediately fatal, contributes to the strain on military resources and the well-being of forces deployed in the region.

Beyond physical injuries, the constant threat of attack takes a psychological toll, requiring troops to operate under persistent stress and vigilance. The need for continuous defensive posture and rapid response to incoming threats adds to the operational burden. The killing of three American troops in a drone attack in Jordan, while not in Iraq, underscored the lethal potential of these attacks and directly led to U.S. retaliatory strikes, demonstrating the immediate and severe consequences that can arise from these confrontations.

The consequences extend beyond the direct casualties, impacting diplomatic relations, regional stability, and the overall perception of security. Each incident where Iran attacks US base in Iraq serves as a stark reminder of the dangers inherent in the current geopolitical climate and the high stakes involved for all parties.

US Response and Defensive Posture

The United States' response to these attacks has largely been characterized by a mix of defensive measures and targeted retaliatory strikes. The primary objective is to protect U.S. personnel and assets while deterring further aggression. This involves deploying advanced air defense systems, enhancing base security, and maintaining a high state of readiness among forces. U.S. officials are constantly monitoring intelligence to anticipate and neutralize threats, often sharing information with Iraqi security forces.

When attacks occur, the U.S. typically conducts investigations to attribute responsibility. If the attacks are deemed significant or result in casualties, the U.S. has demonstrated a willingness to launch retaliatory strikes against the responsible groups and their infrastructure. These responses are carefully calibrated to send a clear message without triggering a broader, uncontrolled escalation. However, the line between deterrence and escalation remains fine, as evidenced by the cycle of attack and counter-attack that has characterized the recent period.

The U.S. has also maintained a diplomatic front, engaging with Iraqi authorities to address the presence of Iran-backed militias and to secure the safety of its forces. This dual approach of military deterrence and diplomatic engagement reflects the complex challenge of operating in a sovereign nation where various armed actors are present.

Escalation Warnings and Regional Implications

The continuous pattern where Iran attacks US base in Iraq carries significant risks of broader regional escalation. The Middle East is bracing for a potential widening of conflicts, especially with the ongoing crisis in Gaza. Iran has explicitly warned the United States, United Kingdom, and France that their bases and ships in the region will be targeted if they help stop Tehran’s strikes on Israel, as reported by Iran’s state media. This warning signals Iran's readiness to expand the conflict if its strategic interests or those of its allies are perceived to be under threat.

Such warnings underscore the interconnectedness of regional conflicts. An attack on a U.S. base in Iraq can have repercussions stretching to the Persian Gulf, the Red Sea, and even beyond. The most recent attacks risk drawing U.S. forces into an offensive role in Israel's war with Iran, a scenario that Washington has largely sought to avoid, thus far limiting its support to defensive measures for Israel in the conflict. Any direct U.S. offensive involvement against Iran could ignite a much larger regional conflagration, drawing in other regional and international powers.

The escalating tensions also affect global energy markets, shipping routes, and international diplomacy. The stability of the Middle East is crucial for global economic and political security, and any significant escalation could have far-reaching consequences for the entire world.

Understanding the Underlying Tensions

The recurring instances of Iran attacks US base in Iraq are not random acts of aggression but are deeply rooted in a complex history of geopolitical rivalry, ideological differences, and strategic competition. At its core, the tension stems from Iran's desire to assert its regional influence and challenge what it perceives as U.S. hegemony in the Middle East. The U.S., on the other hand, aims to maintain stability, protect its allies, and counter what it views as Iran's destabilizing activities.

Key factors contributing to these tensions include:

U.S. Military Presence: The continued presence of U.S. troops in Iraq, even in an advisory or counter-terrorism role, is viewed by Iran and its proxies as an occupation and a threat to regional security.
Proxy Warfare: Iran's strategy of supporting and arming various non-state actors and militias across the region (including in Iraq, Syria, Lebanon, and Yemen) allows it to project power and exert influence without direct military engagement, creating a complex web of proxy conflicts.
Regional Rivalries: The broader rivalry between Iran and its regional adversaries, particularly Saudi Arabia and Israel, often plays out in proxy conflicts across the Middle East, with the U.S. frequently aligned with the latter.
Nuclear Program: Iran's nuclear program remains a significant point of contention, with Western powers and Israel concerned about its potential for weaponization, while Iran insists on its peaceful nature.
Economic Sanctions: U.S. sanctions against Iran, aimed at curbing its nuclear program and destabilizing activities, have severely impacted the Iranian economy, fueling resentment and a desire to challenge U.S. policy.
Gaza Conflict Spillover: The ongoing conflict in Gaza has significantly exacerbated existing tensions, providing a new rallying cry for Iran-backed groups and increasing the frequency of attacks on U.S. and allied targets. The attack comes as tensions escalate in the Middle East, clearly demonstrating this link.

These interwoven factors create a volatile environment where any spark can quickly ignite a larger fire, making the situation in Iraq a critical barometer of regional stability.

The Path Forward: De-escalation or Further Conflict?

The trajectory of future interactions between Iran and the U.S. in Iraq remains uncertain. The current cycle of attacks and retaliations highlights a dangerous equilibrium that could easily tip towards a wider conflict. De-escalation requires a concerted effort from all parties, involving diplomatic channels, clear communication, and a willingness to address underlying grievances.

For the U.S., the challenge lies in protecting its forces and interests while avoiding an uncontrolled escalation. This involves maintaining a strong defensive posture, carefully calibrating responses to attacks, and continuing to engage with Iraqi authorities to ensure the long-term stability of the country. For Iran and its allied groups, the decision to continue or cease attacks will depend on their strategic calculations regarding U.S. presence, regional influence, and the broader context of the Gaza conflict.

Ultimately, the path forward will likely involve a delicate dance between deterrence and diplomacy. The international community, including the United Nations and regional powers, has a crucial role to play in facilitating dialogue and encouraging restraint to prevent the Middle East from descending into a more widespread and devastating conflict. The instances where Iran attacks US base in Iraq serve as constant reminders of the urgent need for a sustainable, peaceful resolution to the region's deep-seated tensions.

In conclusion, the recurring incidents where Iran attacks US base in Iraq are a critical indicator of the volatile geopolitical landscape in the Middle East. From the retaliatory ballistic missile strikes of January 2020 following the assassination of General Soleimani, to the more than 180 attacks carried out by Iran-backed groups since October 2023, these events underscore persistent tensions and the potential for wider conflict. The targeting of key U.S. installations like Al Asad Airbase and the base in Erbil, using rockets and drones, has resulted in injuries to U.S. and coalition personnel, highlighting the real human cost of these confrontations. As regional tensions escalate, particularly in the shadow of the Gaza conflict, the risk of drawing U.S. forces into a broader offensive role looms large. Understanding these dynamics is crucial for grasping the complex interplay of power, proxy warfare, and strategic maneuvering that defines the contemporary Middle East.
