Prof. Andre Hettinger 22 Jun 2025

The Middle East, a crucible of ancient rivalries and modern geopolitical struggles, frequently brings to the forefront the enduring tension between two regional titans: Saudi Arabia and Iran. The question of "Could Saudi Arabia defeat Iran?" is not merely a hypothetical military exercise but a profound inquiry into the complex interplay of historical animosities, strategic vulnerabilities, economic might, and external influences that define the contemporary landscape of the Persian Gulf. As both nations vie for regional dominance, understanding their capabilities and limitations is crucial to grasping the future stability of a volatile yet globally significant area.

This article delves into the multifaceted dimensions of this potential conflict, exploring military strengths, strategic weaknesses, the intricate web of alliances, and the underlying factors that make a direct confrontation both a daunting prospect and a deeply undesirable outcome for all parties involved. We will examine how historical grievances, internal dynamics, and the involvement of global powers shape the balance of power and the likelihood of such a devastating scenario.

Historical Context: A Deep-Rooted Rivalry

The rivalry between Saudi Arabia and Iran is not a recent phenomenon but a historical narrative stretching back decades, deeply entrenched in sectarian, political, and geopolitical differences. These two regional heavyweights have long competed for influence, often through proxy conflicts and ideological battles, rather than direct military confrontation. Understanding this historical backdrop is essential to comprehending the current dynamics and the very question of "Could Saudi Arabia defeat Iran?" in a direct conflict.

The Seeds of Division: Sectarian and Geopolitical Fault Lines

At its core, the Saudi-Iranian rivalry is fueled by a complex mix of factors. Sectarian divisions, with Saudi Arabia championing Sunni Islam and Iran leading the Shia world, form a significant ideological fault line. Politically, both nations aspire to be the dominant power in the Middle East, leading to a zero-sum game where one's gain is perceived as the other's loss. Geopolitically, their interests clash across various regional hotspots, from Yemen and Syria to Lebanon and Iraq.

The Iranian Revolution of 1979, which transformed Iran into an Islamic Republic, marked a turning point, introducing a revolutionary ideology that challenged the monarchical systems prevalent in the Gulf, including Saudi Arabia. This ideological divergence further deepened the chasm between Tehran and Riyadh. For decades, their policies were often diametrically opposed, reflecting profound differences in their visions for regional order. These policies endured for 20 years, shaping the geopolitical landscape of the Middle East.

The Shadow of 9/11: A Course Correction for Saudi Arabia

While the rivalry with Iran was a constant, certain external events also forced Saudi Arabia to re-evaluate its national security priorities. The 9/11 attacks on the United States in 2001—where 15 of the 19 hijackers were Saudi nationals—and the deadly Al Qaeda bombings in Riyadh in 2003, forced a course correction for the Kingdom. These events highlighted the vulnerability of Saudi Arabia to non-state actors and the need to fortify its defenses, not just against traditional state adversaries but also against asymmetric threats. This shift in focus, while not directly about Iran, indirectly influenced Saudi Arabia's defense posture and its approach to regional security, acknowledging that its national security could be threatened from multiple directions.

Military Capabilities: A Comparative Analysis

When considering "Could Saudi Arabia defeat Iran?" in a military sense, a direct comparison of their armed forces reveals a nuanced picture. Both nations possess significant military might, but their strengths and weaknesses are distinct, shaped by different strategic doctrines, access to technology, and geopolitical realities.

Iran's Military Landscape: Strengths and Vulnerabilities

Iran's military, particularly its conventional forces, faces significant challenges. Its air force is old and decrepit, largely comprising aging aircraft from before the 1979 revolution, and its air defenses are porous. This is largely due to years of Western sanctions, which have severely hampered its ability to acquire modern military hardware and maintain existing equipment. Despite these limitations, Iran has developed a formidable asymmetric warfare capability, relying on ballistic missiles, drones, and a network of well-trained proxy forces across the region. Iran cannot defeat Israel militarily, a testament to the limitations of its conventional forces against a technologically superior adversary. This assessment implicitly extends to a comparison with Saudi Arabia, which has invested heavily in modern Western military technology.

However, Iran's strategic depth lies in its Revolutionary Guard Corps (IRGC) and its Quds Force, which are adept at unconventional warfare and supporting proxies. Tehran's long-standing vow to destroy the state of Israel, which it calls the "Zionist regime," underscores its ideological commitment and its willingness to project power through non-traditional means.

Saudi Arabia's Defense Modernization: A Growing Arsenal

In contrast, Saudi Arabia has invested massively in modernizing its armed forces, primarily through purchases from Western nations, particularly the United States. It possesses a technologically advanced air force, state-of-the-art air defense systems, and well-equipped ground forces. This extensive modernization is partly a response to Iran's threat to Saudi national security. To succeed, Crown Prince Mohammed bin Salman must protect the Kingdom, which will require not only fortifying its defenses against further Iranian and Houthi attacks but also establishing a level of deterrence against Tehran.

While Saudi Arabia boasts superior conventional military hardware, the effectiveness of its forces in a sustained, high-intensity conflict against a determined adversary like Iran, particularly one employing asymmetric tactics, remains a subject of debate among military analysts. The ongoing conflict in Yemen, where Saudi Arabia has faced challenges against Houthi forces supported by Iran, offers a glimpse into the complexities of regional warfare.

Strategic Vulnerabilities and Geopolitical Chessboard

Beyond raw military power, the question of "Could Saudi Arabia defeat Iran?" hinges on strategic vulnerabilities and the broader geopolitical chessboard of the Middle East. Both nations face internal challenges and external pressures that would significantly influence the outcome of any direct conflict.

Saudi Arabia's Internal Challenges: Shiite Minorities and Strategic Locations

Saudi Arabia, or better, the Saudi government, has faced unique challenges with its Shiite minorities. While they constitute a relatively small percentage of the population, their geographical distribution presents a strategic vulnerability. There are only two relatively small regions where they are the majority, but they managed to be located in the worst possible strategic places they could be. One such area is right across the southwestern border with Yemen, where there is a social continuity. This proximity to a conflict zone, coupled with potential internal dissent, could pose a significant challenge for Riyadh in a large-scale conflict, potentially diverting resources and attention from external threats.

The Proxy Wars: Yemen and Beyond

The most visible manifestation of the Saudi-Iran rivalry is their involvement in proxy conflicts across the region. Yemen is a prime example, where Saudi Arabia leads a coalition against Houthi rebels, who are widely believed to be supported by Iran. These proxy wars drain resources, exacerbate humanitarian crises, and serve as arenas for both sides to project power and test capabilities without engaging in direct state-on-state warfare. The Houthi attacks, often involving drones and missiles, have demonstrated Iran's ability to threaten Saudi critical infrastructure, including oil facilities, through its proxies. Fortifying its defenses against further Iranian and Houthi attacks is a critical component of Saudi Arabia's national security strategy.

The Role of External Powers: US, Israel, and Beyond

The involvement of external powers profoundly shapes the dynamics between Saudi Arabia and Iran. The United States, a key ally of Saudi Arabia, plays a pivotal role, though its stance is complex. Washington does not even have normal diplomatic relations with Tehran, which it labels the world's most prolific state sponsor of terrorism. This makes the US not a mediator between Iran and Saudi Arabia, but rather a party with its own distinct interests, often aligned with Riyadh against Tehran.

However, US support for Saudi Arabia is not unconditional, and Washington has consistently urged de-escalation. Should a conflict erupt, particularly if Iran entered the conflict between Iran and Israel, Tehran could target American military assets in the region, experts have told Newsweek. This potential for escalation involving US forces adds another layer of complexity and risk, making direct US military intervention on behalf of Saudi Arabia in a direct conflict with Iran a highly calculated decision.

Israel also plays a significant role. Iran cannot defeat Israel militarily, but its continuous threats against the Jewish state create a shared strategic interest between Israel and Saudi Arabia, despite their lack of formal diplomatic ties. Israel may be giving Saudi Arabia more reasons to go after Iran, particularly given Iran's nuclear ambitions and regional destabilization efforts. However, Saudi Arabia will likely refrain from actions that could be seen as aggressive against Iran or helpful to Israel, such as sharing intelligence with Israel on Iran's plans in case of a future cycle of attacks. Similarly, the Kingdom is unlikely to allow Israel and/or the United States to use Saudi airspace to attack Iran or its proxies, demonstrating a cautious approach to avoid being directly drawn into a broader conflict. Trump should keep in mind that the issue of Iran is sufficiently important to both Netanyahu and Saudi Arabia’s Mohammed bin Salman that each side will concede many other things—on Gaza or Palestinian politics on one hand, and on Saudi recognition of Israel on the other. This highlights the centrality of the Iran issue in regional diplomacy.

Deterrence and De-escalation: The Path Forward

Despite the underlying tensions, both Saudi Arabia and Iran have shown a pragmatic understanding of the catastrophic consequences of a direct military confrontation. The focus, particularly for Saudi Arabia, is on establishing a level of deterrence against Tehran. This deterrence is crucial for the success of Saudi Vision 2030, a grand economic diversification plan, as arguably none is greater than Iran’s threat to Saudi national security. To succeed, Crown Prince Mohammed bin Salman must protect the Kingdom.

When Iran and Saudi Arabia agreed to restore diplomatic relations in March 2023, the rapprochement seemed fragile. The two regional powers set modest public expectations for the pact, with supporters hoping it would, at the very least, help contain violence in Arab countries where both states play a role, and prevent new wars from emerging. This diplomatic overture, facilitated by China, indicated a mutual desire to reduce regional tensions, even if the underlying rivalry persists. As former President Barack Obama stated, in the future, Saudi Arabia and Iran would have to come to terms with each other. This sentiment underscores the long-term necessity of dialogue and coexistence, rather than perpetual conflict.

However, the path to lasting peace is fraught with challenges. Iran and Saudi Arabia are led by starkly different men with profoundly different plans, making genuine reconciliation difficult. While a full-scale war is unlikely, low-intensity conflicts, proxy battles, and cyber warfare remain persistent threats.

Economic Implications and Energy Security

The economic dimension is critical to understanding the feasibility and desirability of a conflict. Both Saudi Arabia and Iran are major oil producers, and any disruption to their energy infrastructure or shipping lanes in the Persian Gulf would have devastating global economic consequences. The Strait of Hormuz, a narrow chokepoint through which a significant portion of the world's oil passes, is particularly vulnerable.

Saudi Arabia's Ministry of Energy did not respond to requests for comment regarding specific production moves, but the Kingdom's actions in the global oil market are always closely watched. If Saudi Arabia’s recent production move had been a response to the US, there may not have been much for Iran, but the Kingdom’s efforts to gain access to American technology, says Helima Croft, head of global commodity strategy at RBC Capital Markets, highlights the intricate link between energy policy, foreign relations, and military capabilities. The economic interdependence, both regionally and globally, serves as a powerful disincentive to direct conflict.

The Unlikelihood of Direct Invasion

Despite the constant tension and rhetorical jabs, a full-scale invasion by either Saudi Arabia or Iran against the other is highly improbable. Either one wouldn't want to invade the other. The logistical challenges, the immense human and economic cost, and the certainty of drawing in external powers make such a scenario almost unthinkable. Both nations understand that such an action would destabilize the entire region, potentially leading to a broader conflict with unpredictable outcomes.

While military comparisons like this one exploring a hypothetical conflict between Israel and Saudi Arabia, analyzing air power, ground forces, defense technology, and regional alliances, provide valuable insights into capabilities, they often fall short of capturing the full complexity of geopolitical realities. The strategic calculus for both Riyadh and Tehran leans heavily towards avoiding direct confrontation. Saudi Arabia could also begin to realize that Iran is better left alone, recognizing the futility and destructive nature of an all-out war. Iran, too, appears to be more isolated on the world stage, which might push it towards de-escalation rather than aggressive expansion.

Conclusion: A Complex Web of Interdependencies

The question of "Could Saudi Arabia defeat Iran?" is not a simple yes or no. While Saudi Arabia possesses superior conventional military technology and significant financial resources, Iran counters with a formidable asymmetric warfare capability, strategic depth, and a network of proxies. A direct, conventional military victory for either side is highly unlikely and would come at an unbearable cost.

The enduring rivalry between Saudi Arabia and Iran is a complex tapestry woven with historical grievances, sectarian divides, geopolitical ambitions, and the intricate involvement of global powers. While the threat of conflict remains, both nations seem to understand the catastrophic implications of a full-scale war. The recent diplomatic rapprochement, however fragile, indicates a recognition that managing their differences through dialogue and deterrence, rather than outright confrontation, is the most viable path forward for regional stability. The future of the Middle East hinges not on one side defeating the other, but on their ability to find a way to coexist, however uneasily, in a shared and volatile neighborhood.
