The Historical Context: A Deep-Rooted Rivalry

The animosity between Israel and Iran is not a recent phenomenon; it is rooted in decades of shifting geopolitical alignments and ideological clashes. Prior to the 1979 Islamic Revolution, Israel and Iran maintained cordial, albeit covert, relations. However, the establishment of the Islamic Republic fundamentally altered this dynamic. The new Iranian regime adopted an anti-Zionist stance, viewing Israel as an illegitimate entity and a Western outpost in the Muslim world. This ideological opposition laid the groundwork for a rivalry that has since escalated into a complex "shadow war" fought across multiple fronts.

This shadow war involves cyberattacks, assassinations, sabotage, and, crucially, proxy conflicts. Iran has consistently sought to expand its influence in the region, often at Israel's expense, by supporting various non-state actors. The recent intensification of tensions, particularly marked by events like the Israeli strike on Tehran’s diplomatic compound in Damascus on April 1, which killed at least seven of its military personnel, underscores the volatile nature of this rivalry. This incident, following the war in Gaza, raised tensions between Iran and Israel to new heights, demonstrating the precarious balance of power and the ever-present risk of direct confrontation.

Military Capabilities: A Comparative Analysis

Understanding whether Israel can win a war against Iran requires a detailed examination of their respective military capabilities, doctrines, and strategic assets. Both nations possess unique strengths and vulnerabilities that would shape the contours of any large-scale conflict.

Israel's Military Prowess

Israel's defense doctrine is built on qualitative military superiority, emphasizing advanced technology, intelligence gathering, and a highly professional and well-trained military. The Israel Defense Forces (IDF) are renowned for their air force, considered one of the most advanced globally, equipped with F-35 stealth fighters and other sophisticated aircraft. This air superiority would be critical for deep strikes and maintaining air dominance.

Furthermore, Israel possesses a multi-layered air defense system, including the Iron Dome for short-range rockets, David's Sling for medium-range threats, and the Arrow system designed to intercept ballistic missiles outside the atmosphere. These systems have proven effective against various threats, though their capacity against a massive, sustained barrage remains a point of debate. Israel also maintains a robust intelligence apparatus, capable of gathering crucial information on Iranian activities and capabilities. Historically, Israel has demonstrated the capacity to conduct precision strikes against high-value targets, as evidenced by reports of its ability to weaken Iran's military leadership, including nearly its entire air command, through targeted operations. While undeclared, Israel is widely believed to possess nuclear weapons, serving as a powerful deterrent in any existential threat scenario.

Iran's Asymmetric Warfare Doctrine

In contrast, Iran's military doctrine emphasizes asymmetric warfare, leveraging its vast geographical size, large population, and a diverse arsenal of missiles, drones, and naval assets to offset the technological superiority of its adversaries. The Islamic Revolutionary Guard Corps (IRGC) plays a central role, operating as a parallel military force with significant ideological and operational autonomy, responsible for projecting power through its Quds Force and supporting regional proxies.

Iran has invested heavily in its ballistic missile program, developing a wide range of short, medium, and long-range missiles capable of striking targets across the Middle East. These missiles, coupled with an increasingly sophisticated drone program, represent Iran's primary means of projecting force directly against Israel. For instance, Iran's daring UAV attack against Saudi oil facilities in the past might provide a model for how it would fight against Israel, showcasing its ability to conduct complex, coordinated drone and missile strikes. According to the IDF, Iran has demonstrated its capacity for large-scale missile attacks, reportedly using 120 MRBMs in an April 13 attack last year on Israel, another 200 on October 1, and a total of 380 in a recent five-day period. While this tally would deplete its overall known stockpiles, it highlights Iran's willingness and capability to launch significant barrages. Beyond missiles and drones, Iran also possesses a large ground force, including both the regular army and the IRGC, and a significant naval presence in the Persian Gulf, capable of disrupting maritime trade routes.

The Axis of Resistance: Iran's Regional Strategy

A crucial element in understanding Iran's strategic posture and its capacity to wage war against Israel is its "Axis of Resistance." This network of state and non-state actors, including Hezbollah in Lebanon, Hamas and Palestinian Islamic Jihad in Gaza, various Shiite militias in Iraq and Syria, and the Houthi movement in Yemen, provides Iran with strategic depth and the ability to project power across multiple fronts without direct military engagement. Tehran explicitly aims to impose a new strategic reality on Israel by establishing military linkage and potential interdependence between the battlefields of Gaza, Iraq, Syria, Lebanon, and beyond.

The intensification of violence between Israel and Hezbollah, for instance, is fundamentally a contest of wills between Israel and Iran. Hezbollah, heavily armed and trained by Iran, represents the most potent proxy threat on Israel's northern border, possessing a vast arsenal of rockets and missiles capable of striking deep into Israeli territory. By mobilizing its entire “axis of resistance,” Iran has effectively drawn Israel into a war of attrition, forcing it to conduct costly military operations not just in Gaza and the West Bank, but also in Lebanon, Syria, Iraq, Yemen, and potentially even in Iran itself. This multi-front pressure is designed to stretch Israel's resources, drain its economy, and test its societal resilience, making a decisive "win" in a traditional sense far more elusive for Israel.

Potential Scenarios of Conflict Escalation

A full-scale war between Israel and Iran could unfold in several ways, each with devastating consequences for the region and potentially the world. The complexity arises from the interplay of direct military actions, proxy engagements, and the potential for international intervention.

Direct Confrontation and Missile Barrages

One primary scenario involves direct military exchanges, characterized by massive missile and drone barrages. Iran has demonstrated its willingness to retaliate directly, as seen when it fired more than 180 ballistic missiles against Israel in a recent unprecedented attack. Such a scenario would involve Iran launching a significant portion of its missile and drone arsenal from its own territory, aiming to overwhelm Israel's air defenses and inflict damage on strategic and civilian targets. While Israel's air defense systems are robust, a sustained, high-volume attack could lead to some missiles making it through, causing casualties and disruption. A second possibility is that Iran hangs on and even gets in a few blows against Israel—whether in the form of terrorism, or a few missiles that make it through Israeli defenses. This highlights Iran's intent to inflict damage and demonstrate its retaliatory capacity, even if not achieving a decisive military victory.

Israel's Retaliatory Strikes and Strategic Targets

In response to direct Iranian attacks, Israel would likely launch massive retaliatory strikes. Israel’s war cabinet has met several times to debate a course of action to complement a diplomatic push against Iran since Saturday’s unprecedented direct attacks on Israel, with the Israeli army preparing for various contingencies. A key objective for Israel would be to degrade Iran's military capabilities, particularly its missile and nuclear programs. The first is that Israel plans to hit the nuclear facilities harder as the war goes on, indicating a strategic intent to neutralize Iran's potential for nuclear weapons development. Beyond nuclear sites, Israeli targets would likely include missile launch sites, command and control centers, air defense systems, and critical infrastructure within Iran. The goal would be to cripple Iran's ability to wage war and deter further aggression, but such strikes carry the immense risk of further escalation and broadening the conflict.

The Role of International Actors and Alliances

Any major conflict between Israel and Iran would inevitably draw in international actors, most notably the United States. The U.S. has a long-standing security commitment to Israel and a significant military presence in the Middle East. The question of what happens if the United States bombs Iran has been a subject of intense debate among experts, with the U.S. weighing the option of heading back into a war in the Middle East. Such a decision would dramatically alter the scope and intensity of the conflict, potentially involving U.S. air power, naval assets, and intelligence capabilities to support Israel or directly target Iran. However, U.S. involvement also carries the risk of a wider regional conflagration, potentially drawing in other global powers like Russia and China, who have their own interests and relationships in the region.

Beyond the major powers, regional Arab states would also play a critical role. While some Arab nations have historically been wary of Iran's regional ambitions and have forged closer ties with Israel through the Abraham Accords, a direct conflict could force difficult choices. Their responses could range from providing logistical support to either side, to maintaining strict neutrality, or even facing internal instability due to the conflict's ripple effects. The complex web of alliances and rivalries ensures that a war between Israel and Iran would not remain a bilateral affair but would rapidly become a regional and potentially global crisis.

The Human and Economic Cost of Conflict

The human and economic costs of a full-scale war between Israel and Iran would be catastrophic. Both nations possess the capacity to inflict significant damage, leading to widespread civilian casualties, massive displacement, and severe humanitarian crises. Modern warfare, as seen in various conflicts globally, including the drone barrage used by the RSF in Sudan, often puts civilians in the crosshairs, and a conflict of this scale would be no different. Infrastructure would be destroyed, essential services disrupted, and the fabric of society severely strained.

Economically, the impact would be felt far beyond the immediate combat zones. The Middle East is a vital hub for global energy supplies, and any disruption to oil and gas production or shipping routes in the Persian Gulf would send shockwaves through the global economy. Oil prices would skyrocket, supply chains would be disrupted, and investor confidence would plummet, potentially triggering a global recession. The long-term costs of reconstruction, refugee resettlement, and addressing the psychological trauma of war would burden both nations and the international community for decades. The war would also divert resources from development and social programs, exacerbating existing challenges and hindering progress in the region.

Defining "Victory" in a War Against Iran

The concept of "winning" in a war against Iran is far from straightforward. In a traditional military sense, victory often implies the complete defeat and surrender of the enemy. However, given the nature of the Israeli-Iranian rivalry, the capabilities of both sides, and the involvement of proxies, a clear-cut military victory for either side is highly improbable and perhaps even undesirable.

For Israel, a "win" might involve severely degrading Iran's nuclear program, dismantling its missile capabilities, and significantly weakening its network of regional proxies. However, achieving these objectives would likely come at an immense cost, including potential damage to its own infrastructure, casualties, and a sustained period of regional instability. Even if Israel could achieve these military aims, it would face the challenge of managing a potentially destabilized Iran, which could lead to further unpredictable consequences, including internal unrest or a more radicalized regime.

For Iran, "victory" might not be about conventional military conquest but rather about demonstrating its resilience, its ability to inflict pain on Israel, and its continued influence in the region. Even if it "hangs on and gets in a few blows against Israel," whether through terrorism or missile attacks, Iran might consider this a success in its asymmetric struggle. The war of attrition, which Iran has effectively drawn Israel into through its "Axis of Resistance," aims to exhaust Israel rather than defeat it outright. Therefore, the question of whether Israel can win a war against Iran depends heavily on how "winning" is defined. A decisive military victory in the traditional sense seems unlikely, and any outcome would likely be a complex, costly, and protracted struggle with no clear victor, but rather a new, potentially more dangerous, geopolitical reality.

In conclusion, while Israel possesses superior technological capabilities and a highly trained military, Iran's asymmetric warfare doctrine, vast missile arsenal, and extensive network of regional proxies present a formidable and multifaceted challenge. A full-scale war would be catastrophic for both nations and the wider Middle East, with immense human and economic costs. The involvement of international actors, particularly the United States, would further complicate the dynamics, potentially escalating the conflict beyond regional borders. Ultimately, "winning" in such a scenario would not be a simple military triumph but a complex, costly, and uncertain outcome, leaving both nations and the region profoundly transformed.
