Kenyon Legros 21 Jun 2025

The geopolitical landscape of the Middle East has long been shaped by a profound and complex rivalry between two regional powerhouses: Iran and Saudi Arabia. This enduring antagonism, rooted in a potent mix of sectarian, political, and geopolitical differences, has manifested in a series of proxy conflicts across the region, casting a long shadow over stability and peace. Understanding the intricate dynamics of the Iran-Saudi rivalry is crucial to comprehending the broader challenges and opportunities within this strategically vital part of the world.

For decades, these two nations have found themselves on opposing sides of the deadliest conflicts, backing rival factions in a high-stakes geopolitical chess match. From the battlefields of Yemen and Syria to the political arenas of Iraq and Lebanon, their competition has fueled instability, exacerbated humanitarian crises, and drawn in global powers. Yet, amidst the long history of animosity, there have also been recent glimmers of diplomatic efforts, suggesting a potential, albeit fragile, shift in their contentious relationship.

Historical Roots of Rivalry

The animosity between Iran and Saudi Arabia is not a recent phenomenon; it's a deep-seated rivalry with roots stretching back decades, profoundly shaped by historical trajectories and contrasting national identities. Historically, Saudi Arabia and Iran have been regional rivals, divided by a complex interplay of sectarian, political, and geopolitical differences. For many years, the policies of both nations, particularly during the Cold War era, were characterized by a certain stability, even if it was a stability built on cautious distance rather than genuine amity. These policies, for instance, endured for 20 years, setting a precedent for how each state viewed its role and the role of its counterpart in the regional order.

However, significant global events have often served as catalysts, forcing a re-evaluation and, at times, a dramatic course correction in their relationship. A pivotal moment arrived with the 9/11 attacks on the United States in 2001. The fact that 15 of the 19 hijackers were Saudi nationals, coupled with the deadly Al Qaeda bombings in Riyadh in 2003, compelled Saudi Arabia to reassess its internal and external policies. This period marked a shift, pushing the Kingdom towards a more assertive stance against extremism, which inadvertently intensified the underlying geopolitical competition with Iran as both sought to define the region's future.

Sectarian Divides and Geopolitical Chessboard

At the heart of the Iran-Saudi Arabia conflict lies a fundamental sectarian divide: Iran is predominantly Shiite, while Saudi Arabia is the bastion of Sunni Islam. This theological difference, while not the sole driver, often serves as a powerful ideological lens through which political and geopolitical rivalries are viewed and justified. It fuels narratives of legitimacy and leadership within the Islamic world, with both nations vying for influence and moral authority. This deep sectarian chasm is constantly exploited and exacerbated by political ambitions, transforming religious distinctions into potent tools for regional power projection.

Beyond sectarianism, the geopolitical chessboard sees both nations competing for strategic dominance. Over the last two decades, Iran and Saudi Arabia have been on opposing sides of virtually every major and deadliest conflict in the Middle East. Their competition is not merely about territory or resources, but about shaping the very ideological and political future of the region. This rivalry is evident in their contrasting visions for governance, alliances, and even their relationships with global powers. While Saudi Arabia often aligns with Western powers, Iran has historically pursued an anti-Western stance, seeking to establish an "axis of resistance" that challenges the existing regional order. This fundamental divergence in worldview ensures that nearly every crisis in the Middle East becomes a proxy battleground for their broader struggle.

Proxy Battlegrounds: Yemen, Syria, Iraq, and Beyond

The most visible and devastating manifestations of the Iran-Saudi Arabia rivalry are the proxy wars fought across the Middle East. These conflicts, often framed as internal struggles, are frequently exacerbated and prolonged by the external support provided by Riyadh and Tehran to opposing factions. The two have backed rival groups in Iraq, Syria, and Yemen, as well as in Lebanon and the Palestinian territories, turning these nations into unfortunate arenas for their geopolitical contest.

The Yemeni Quagmire: A Proxy Flashpoint

Perhaps the most tragic and protracted example of this proxy warfare is the civil war in Yemen. When the conflict began in 2015, Saudi Arabia backed its internationally recognized government and targeted Houthi rebel strongholds. The Houthis, a Zaydi Shiite group, are aligned with Iran, receiving varying degrees of support, training, and weaponry from Tehran. This alignment transformed Yemen into a direct proxy confrontation, with devastating humanitarian consequences. The conflict has seen repeated Houthi missile and drone attacks targeting Saudi territory. For example, on December 6, 2021, Saudi air defenses intercepted a ballistic missile above Riyadh, causing shrapnel to fall in several areas, a clear illustration of the direct threat emanating from this proxy front.

Syria and Iraq: Contested Spheres of Influence

In Syria, the Iran-Saudi Arabia rivalry played a significant role in prolonging the civil war. Iran staunchly supported the Assad regime, providing military aid, advisors, and mobilizing Shiite militias, viewing Syria as a crucial link in its "axis of resistance." Conversely, Saudi Arabia, along with other Gulf states, supported various Sunni rebel groups seeking to overthrow Assad. This external intervention turned the Syrian conflict into a complex multi-layered war, with both regional powers investing heavily in their respective proxies. Similarly, in Iraq, post-2003, both Iran and Saudi Arabia have vied for influence, backing different political blocs and militias, further complicating Iraq's path to stability. The dynamic is also evident in Libya, where Iran and Saudi Arabia have waged a proxy war. Saudi Arabia, along with the UAE [486], Egypt, and Sudan, have provided support to the Libyan National Army and its leader, warlord Khalifa Haftar [485], highlighting the expansive reach of their regional competition.

Critical Incidents and Escalation Points

While proxy wars represent a constant low-level conflict, certain incidents have dramatically escalated tensions, pushing the Iran-Saudi Arabia rivalry to the brink of direct confrontation. These moments serve as stark reminders of the fragility of regional peace and the high stakes involved.

The Aramco Attacks: A Wake-Up Call

A particularly alarming incident occurred in September 2019 when Saudi Aramco’s facilities, vital to global oil supplies, were struck by 18 drones and three missiles. This sophisticated attack showcased Iran's offensive capabilities and, more critically, Saudi Arabia’s vulnerability. While Iran stringently denied involvement, the projectiles were later traced back to Iran. The desire to avoid a repeat of such a devastating incident prompted a new and sustained effort by Saudi Arabia and other Arab nations to seek de-escalation, recognizing the immense economic and security risks posed by continued aggression. This attack was a significant wake-up call for Riyadh, demonstrating the need for new approaches to manage the Iran-Saudi Arabia dynamic.

US Drone Incident and Regional Posture

The Aramco attacks followed another critical event earlier that year. When Iran downed a US surveillance drone in June 2019 and Washington opted against retaliatory strikes, the Islamic Republic appeared to escalate its posture. This perceived lack of a strong US response emboldened Iran, leading to the subsequent, more aggressive actions against Saudi infrastructure. This sequence of events underscored the interconnectedness of regional security and the role of international actors in influencing the Iran-Saudi Arabia dynamic. It highlighted how perceived weakness or strength on the part of external powers can directly impact the calculus of escalation in the Middle East.

Diplomatic Overtures and De-escalation Efforts

Despite the long history of animosity and recurring flashpoints, there have been concerted efforts to de-escalate tensions and foster dialogue between Iran and Saudi Arabia. The immense costs of perpetual conflict, both human and economic, have driven various regional and international actors to push for rapprochement.

Beijing's Role in Rapprochement

A significant breakthrough occurred recently when Beijing successfully brokered a rapprochement between regional foes Iran and Saudi Arabia. This diplomatic achievement, announced in March 2023, saw the two nations agree to restore diplomatic ties after years of estrangement. China's emergence as a peacemaker in the Middle East marks a notable shift in global diplomacy, demonstrating a desire for stability from a major economic power. Beijing has also said it is prepared to act as peacemaker in the escalating conflict between Israel and Iran after having successfully brokered this initial rapprochement, indicating a broader ambition for regional peace.

Beyond China's intervention, other regional players have also engaged in frantic efforts at diplomacy to end conflicts and ensure peace and stability in the wider region. Saudi Arabia, the UAE, Oman, and Qatar are actively involved in these discussions. For instance, the Sultan of Oman had a call with the Iranian president, while foreign ministers from Saudi Arabia, the UAE, Qatar, and Kuwait have been engaging in high-level talks. Qatar’s emir spoke with Pezeshkian and received a letter from him, further signaling a concerted regional push for dialogue and de-escalation. These multi-faceted diplomatic efforts highlight a growing recognition that sustained regional instability serves no one's long-term interests.

The Impact on Regional Stability and Global Interests

The Iran-Saudi Arabia rivalry extends far beyond their borders, profoundly impacting regional stability and global interests, particularly concerning energy security. The Middle East, a crucial source of the world's oil, remains highly susceptible to disruptions caused by this ongoing tension. Israel’s sudden attack on Iran, for example, has threatened to disrupt oil supplies in the Middle East, placing the OPEC+ alliance under renewed scrutiny and highlighting the fragility of the global energy market in the face of regional conflict. The Kingdom of Saudi Arabia also came in Iran’s support regarding this incident and said, “the kingdom…” demonstrating a complex interplay of regional interests and a cautious approach to broader escalation.

The ripple effects are felt across the globe. Major powers, including the United States, closely monitor the Iran-Saudi Arabia dynamic, as it directly influences their strategic interests, from counter-terrorism efforts to ensuring freedom of navigation in vital waterways. The rivalry also creates a fertile ground for extremist ideologies, as both sides, at various points, have been accused of inadvertently or directly fueling radical groups in their pursuit of regional dominance. The long-term stability and economic prosperity of the Middle East, and by extension, the global economy, hinge significantly on finding a sustainable pathway to de-escalation and cooperation between these two influential nations.

Divergent Leadership, Divergent Visions

A critical element shaping the Iran-Saudi Arabia relationship is the stark contrast in their leadership and their profoundly different plans for their respective nations and the region. Iran is led by a complex clerical-political establishment, with the Supreme Leader holding ultimate authority, guided by revolutionary ideals and a vision of regional resistance against perceived Western hegemony. Their foreign policy is often characterized by a long-term strategic patience and a willingness to challenge the status quo, as seen when Iran downed a US surveillance drone in June 2019 and Washington opted against retaliatory strikes, leading to the Islamic Republic escalating its posture—striking Saudi Aramco’s facilities in September 2019 with 18 drones and three missiles, showcasing its offensive capabilities and Saudi Arabia’s vulnerability.

Saudi Arabia, on the other hand, is an absolute monarchy with a younger, more assertive leadership under Crown Prince Mohammed bin Salman, who is driving an ambitious reform agenda aimed at diversifying the economy and modernizing society. Riyadh's foreign policy prioritizes regional stability, economic development, and countering what it perceives as Iranian expansionism. The differing domestic priorities and ideological frameworks of these leaders contribute significantly to the enduring tension. Their distinct visions for their nations' futures often clash, making genuine, lasting reconciliation a formidable challenge, even amidst diplomatic overtures. If Saudi Arabia chooses to support Iran, it could do so in several strategic ways, indicating a complex web of potential alliances and rivalries that shifts based on perceived threats and opportunities.

The Path Forward: Navigating a Complex Future

The future of the Iran-Saudi Arabia relationship remains uncertain, characterized by a delicate balance between entrenched rivalry and nascent diplomatic engagement. While the recent Beijing-brokered rapprochement offers a glimmer of hope, it is merely a first step on a long and arduous path. The deep-seated issues—sectarian divides, geopolitical competition, and proxy conflicts—will not disappear overnight. The most significant attack Iran has faced since its 1980s war with Iraq, which appeared to be the 2019 Aramco strike, underscores the potential for rapid escalation and the urgent need for sustained dialogue.

Moving forward, both nations face immense pressure to prioritize stability for their own economic development and regional security. The upcoming Riyadh summit in 2025, for example, could serve as another platform for continued engagement and potentially deeper cooperation. The international community, including major powers like China and the United States, will continue to play a crucial role in encouraging de-escalation and facilitating dialogue. The challenge lies in translating diplomatic breakthroughs into tangible reductions in proxy conflicts and a greater commitment to peaceful coexistence. The path ahead requires consistent effort, mutual trust-building, and a pragmatic recognition that the costs of perpetual conflict far outweigh the benefits of continued rivalry. Only through sustained engagement can the Middle East hope to move beyond the shadow of the Iran-Saudi Arabia conflict towards a more stable and prosperous future.
