The Historical Roots of Rivalry

The animosity between Iran and Saudi Arabia is not a recent phenomenon; it is deeply embedded in their respective histories and geopolitical aspirations. While both nations share a long-standing presence in the Middle East, their paths diverged significantly, laying the groundwork for what would become the enduring Iran-Saudi Arabia conflict. Historically, relations between Iran and Saudi Arabia have traditionally been marked by tension and hostility, a sentiment that escalated dramatically following a pivotal event in Iranian history.

The 1979 Iranian Revolution's Impact

A major turning point in the relationship was the 1979 Iranian Revolution, which overthrew the Pahlavi monarchy. This seismic event transformed Iran into an Islamic Republic, fundamentally altering its foreign policy from a pro-Western stance to one based on revolutionary Islamic principles. The new Iranian leadership, with its explicit aim of exporting its revolution, was perceived as a direct ideological threat by the conservative, monarchical Saudi Arabia. The Saudis, guardians of Islam's holiest sites and proponents of a different interpretation of Islamic governance, viewed Iran's revolutionary fervor as a challenge to their own legitimacy and regional influence. This ideological clash quickly translated into a geopolitical struggle, setting the stage for decades of an intense Iran-Saudi Arabia conflict.

Early Attempts at Regional Responsibility (1960s)

Interestingly, before the revolutionary shift, there were periods of cooperation, albeit cautious. In 1968, Saudi Arabia and Iran signed a demarcation agreement, signaling a degree of practical engagement. This period, particularly in the late 1960s, saw both nations stepping up to assume primary responsibility for peace and security in the region. This came about when the United Kingdom announced it would withdraw and vacate the Persian Gulf, creating a power vacuum. The Shah of Iran, in the late 1960s, even sent a series of letters to King Faisal, urging him to collaborate on regional stability. These early attempts at shared responsibility, however, were ultimately overshadowed by the profound ideological and political schism that emerged post-1979, cementing the trajectory of the Iran-Saudi Arabia conflict.

Sectarian Fault Lines: Sunni vs. Shia

Beyond historical and geopolitical ambitions, the Iran-Saudi Arabia conflict is often framed through the lens of sectarianism. Iran and Saudi Arabia's status as leading exponents of Shia and Sunni Islam respectively have informed much of their rivalry. While it's an oversimplification to attribute the entire conflict solely to religious differences, sectarianism is an ugly reality in many of the conflicts raging today, often exploited by political actors to rally support and demonize opponents. This religious divide serves as a powerful narrative, fueling animosity and providing a convenient framework for understanding the alliances and antagonisms across the region.

Iran, as the world's largest Shia-majority nation, sees itself as the protector of Shia communities globally, from Lebanon to Iraq and Yemen. Saudi Arabia, on the other hand, is the birthplace of Islam and the custodian of its holiest sites, adhering to a conservative Wahhabist interpretation of Sunni Islam. This fundamental difference in religious identity and interpretation has often been weaponized, transforming local grievances into broader sectarian proxy battles. The rhetoric from both sides frequently casts the other as a threat to the true essence of Islam, further entrenching the divide and making resolution of the Iran-Saudi Arabia conflict even more challenging.

Proxy Wars: Battlegrounds Across the Region

Over the last two decades, Iran and Saudi Arabia have been on opposing sides of the deadliest conflicts in the Middle East. This proxy warfare is perhaps the most visible and destructive manifestation of the Iran-Saudi Arabia conflict, with both nations backing rival groups to advance their respective interests and undermine the other's influence. The human cost of these proxy battles has been immense, leading to widespread displacement, humanitarian crises, and regional instability.

Iraq, Syria, and Yemen: The Main Arenas

The most prominent battlegrounds for the Iran-Saudi Arabia conflict have been Iraq, Syria, and Yemen. In Iraq, following the 2003 US-led invasion, Iran significantly expanded its influence by supporting various Shia political parties and militias. Saudi Arabia, wary of a Shia-dominated Iraq aligned with Iran, often supported Sunni factions, further deepening the sectarian divide. In Syria, the civil war saw Iran providing crucial military and financial support to the Assad regime, while Saudi Arabia backed various rebel groups aiming to overthrow him. This created a direct clash of interests, prolonging the devastating conflict.

Yemen, however, has become perhaps the most direct and brutal proxy war. Saudi Arabia launched a military intervention in 2015 to support the internationally recognized government against the Houthi rebels, whom Riyadh accuses of being Iranian proxies. Iran, while denying direct military involvement, has openly expressed support for the Houthis, seeing them as a strategic counterweight to Saudi influence. This protracted conflict has led to one of the world's worst humanitarian crises, a direct consequence of the escalating Iran-Saudi Arabia conflict.

Lebanon and Palestinian Territories: Extended Influence

The reach of the Iran-Saudi Arabia conflict extends beyond these major battlefields to other sensitive areas. In Lebanon, Iran's strong backing of Hezbollah, a powerful Shia political party and militant group, has long been a source of contention for Saudi Arabia, which has historically supported Sunni political figures and institutions. The rivalry plays out in the country's delicate sectarian power-sharing arrangements, often leading to political paralysis and instability.

Similarly, in the Palestinian territories, both Iran and Saudi Arabia have sought to exert influence, though with different approaches. Iran has provided support to various Palestinian factions, including Hamas and Palestinian Islamic Jihad, aligning itself with the "resistance axis." Saudi Arabia, while historically a strong supporter of the Palestinian cause, has often focused on diplomatic and financial aid through official channels, wary of groups linked to Iran. This competition for influence further complicates the already volatile Israeli-Palestinian dynamic, demonstrating the pervasive nature of the Iran-Saudi Arabia conflict.

Escalations and Direct Confrontations

While much of the Iran-Saudi Arabia conflict has been fought through proxies, there have been moments of direct confrontation or near-direct attacks that underscore the volatile nature of their relationship. These incidents highlight the potential for the rivalry to spill over into broader, more dangerous regional conflicts.

A stark example occurred in 2019, when the Abqaiq oil processing plant in Saudi Arabia was damaged in an attack. Saudi Arabia was the first Arab nation to speak out against the attacks, stating that the kingdom believed Iran was responsible. This incident, which severely impacted global oil supplies, was widely attributed to Iran or its proxies, and it appeared to be the most significant attack Iran has faced since its 1980s war with Iraq. The attack demonstrated Iran's capability to strike at the heart of Saudi Arabia's economic infrastructure, raising fears of a direct military escalation.

Another recurring threat has been ballistic missile attacks targeting Saudi territory, often launched by Houthi rebels from Yemen. For example, on December 6, 2021, Saudi air defenses intercepted a ballistic missile above Riyadh, causing shrapnel to fall in several areas. These attacks, which Saudi Arabia attributes to Iranian-backed groups, serve as a constant reminder of the ongoing security challenges posed by the Iran-Saudi Arabia conflict and the reach of Iranian influence through its allies. Such incidents underscore the inherent instability and the constant threat of miscalculation that defines this tense relationship.

Shifting Alliances and Diplomatic Overtures

Despite the deep-seated animosity and history of conflict, the Middle East is a region of complex and shifting allegiances. Saudi Arabia’s response to various regional developments, including the recent Israel-Iran tensions, may best illustrate this fluidity. While traditionally described as Iran’s regional rival, recent years have seen a cautious re-evaluation of strategies by Saudi Arabia, driven by a desire for regional de-escalation and economic diversification.

The realization that perpetual conflict is detrimental to economic development and stability has prompted both sides, and their regional neighbors, to explore diplomatic avenues. Today, though, the Saudis are worried about antagonizing their regional neighbour, lest Iran blame the kingdom for egging on the war and decide to attack it (as it did in 2019). This apprehension has led to a more pragmatic approach, prioritizing stability over outright confrontation. Saudi Arabia, the UAE, Oman, and Qatar are engaged in frantic efforts at diplomacy to end regional conflicts and ensure peace and stability in the wider region, recognizing that their economic futures are intertwined with a stable environment.

The Beijing-Brokered Rapprochement

A significant breakthrough in the long-standing Iran-Saudi Arabia conflict occurred in March 2023, when Beijing successfully brokered a rapprochement between the two regional foes. This diplomatic coup by China, a rising global power with significant economic interests in the Middle East, surprised many observers and marked a potential turning point in regional dynamics. The agreement saw both countries agree to restore diplomatic ties, reopen embassies, and reactivate a security cooperation agreement signed in 2001.

The motivations for this reconciliation were multifaceted. For Saudi Arabia, it offered a chance to de-escalate regional tensions, particularly in Yemen, and focus on its ambitious Vision 2030 economic transformation plan, which requires a stable environment. For Iran, it provided a diplomatic lifeline amidst international isolation and sanctions, potentially easing economic pressures and strengthening its regional standing. Beijing, for its part, positioned itself as a neutral peacemaker, enhancing its diplomatic credibility and safeguarding its energy interests in the region. This development underscores the complex interplay of regional and global powers in shaping the future of the Iran-Saudi Arabia conflict.

Navigating New Regional Realities

The recent rapprochement, while significant, does not erase decades of deep-seated mistrust and rivalry. The Middle East continues to be a volatile region, and the Iran-Saudi Arabia conflict, though perhaps less overtly hostile, remains a defining feature. Both nations are now navigating a new set of regional realities, where pragmatic cooperation might coexist with underlying strategic competition.

Saudi Arabia's Stance on Israel-Iran Tensions

A crucial aspect of this new reality is Saudi Arabia's evolving stance on the broader Israel-Iran tensions. Saudi Arabia has secured assurances from Iran that the former will be shielded from any conflict with Israel, while Riyadh has promised Tehran that Saudi airspace won’t be used for any strikes by the United States or Israel. True to this commitment, the kingdom did not allow Israel to use its airspace during Tel Aviv’s most recent strikes. This indicates a strategic shift by Riyadh, prioritizing its own security and regional stability over aligning directly with one side in a potential wider conflict. Saudi Arabia on Friday condemned Israel’s strikes on Iran that targeted its nuclear facilities, ballistic missile factories, and military commanders, further demonstrating its commitment to de-escalation and its independent foreign policy, even in the face of its historical rivalry with Iran.

This position highlights a growing maturity in Saudi foreign policy, moving away from purely confrontational approaches. If Saudi Arabia chooses to support Iran in de-escalation, it could do so in several strategic ways, such as continuing to provide diplomatic channels, urging restraint, and using its influence to prevent further escalation. This nuanced approach suggests a recognition that a full-blown regional war, regardless of who is involved, would be catastrophic for all, including Saudi Arabia's ambitious economic transformation plans.

The Future of Iran-Saudi Relations

The future of the Iran-Saudi Arabia conflict is likely to be characterized by a delicate balance of cooperation and competition. While the Beijing-brokered deal has opened channels for dialogue and reduced immediate tensions, the underlying sectarian, political, and geopolitical differences that have historically divided them remain potent. The two have backed rival groups in Iraq, Syria, and Yemen, as well as in Lebanon and the Palestinian territories, and unwinding these entrenched networks of influence will take considerable time and effort.

The success of the rapprochement will depend on the willingness of both Tehran and Riyadh to adhere to their commitments, address mutual security concerns, and find common ground on regional issues. Continued diplomatic efforts, perhaps involving other regional and global powers, will be essential to transform a fragile truce into a more durable peace. The world watches closely, as the trajectory of the Iran-Saudi Arabia conflict will undoubtedly continue to shape the destiny of the Middle East and beyond.

Conclusion

The Iran-Saudi Arabia conflict is a deeply entrenched rivalry, born from historical shifts, ideological divides, and competing geopolitical ambitions. For decades, it has manifested in devastating proxy wars, economic disruptions, and persistent regional instability. However, recent diplomatic breakthroughs, particularly the Beijing-brokered rapprochement, signal a cautious but significant shift towards de-escalation and a more pragmatic approach to regional security.

While challenges remain, and the path to lasting peace is fraught with complexities, the willingness of both Iran and Saudi Arabia to engage in dialogue offers a glimmer of hope for a more stable Middle East. Understanding this intricate dance of rivalry and diplomacy is vital for anyone seeking to grasp the dynamics of this pivotal region.
