If Iran Goes To War With Israel: Unpacking The Dire Consequences

Monserrat Green 24 Jun 2025

The prospect of direct warfare between Israel and Iran looms as a significant and deeply concerning possibility in the Middle East, a scenario that carries profound implications not just for the immediate region but for global stability. While fortunately, war between Israel and Iran currently appears to be unlikely, the ongoing conflict in Gaza means the risk of an incident igniting a wider regional conflict remains acutely high. This article delves into the complex history, recent escalations, and potential ramifications should direct hostilities erupt, exploring what it would mean for the Middle East and beyond.

The relationship between these two regional powers has long been characterized by a shadow war, fought through proxies, cyberattacks, and covert operations. However, recent events have pushed the adversaries closer to the precipice of open confrontation than ever before. Understanding the multifaceted layers of this tension is crucial to grasping the potential devastation should direct warfare between Israel and Iran become a reality.

A History of Shadows: The Long-Standing Iran-Israel Tensions

The animosity between Iran and Israel is deeply rooted, stretching back decades. While once allies under the Shah, the 1979 Iranian Revolution fundamentally reshaped the geopolitical landscape. The new Islamic Republic adopted an anti-Zionist stance, viewing Israel as an illegitimate entity and a Western outpost in the Muslim world. This ideological clash has fueled a persistent, often covert, struggle for regional dominance. The tension is palpable, as evidenced by events like Iranian protesters burning representations of the U.S. and Israeli flags in Tehran on June 8, 2018, a symbolic act reflecting deep-seated resentment.

One way to look at Israel’s war with Iran, or rather, the ongoing skirmishes and confrontations, is that it’s a natural escalation of the battles that the Jewish state has been fighting for years. It’s a prolonged, simmering conflict that occasionally boils over, threatening to engulf the entire region. The stakes are incredibly high, and the potential for miscalculation is ever-present.

The Proxy Battlefield: From Damascus to Gaza

For years, the conflict between Iran and Israel has largely been fought through proxies. Iran supports groups like Hezbollah in Lebanon, Hamas and Palestinian Islamic Jihad in Gaza, and various Shiite militias in Iraq and Syria. These groups often act as extensions of Iran’s foreign policy, allowing Tehran to exert influence and challenge Israeli security without direct military engagement. Israel, in turn, has conducted numerous strikes in Syria, targeting Iranian assets, weapons shipments, and military personnel, often in an effort to prevent advanced weaponry from reaching Hezbollah.

The bombing of the Iranian embassy in Damascus in April of last year, widely attributed to Israel, marked a significant escalation, leading to Iran firing missile barrages at Israel. This incident underscored the fragility of the status quo and the constant threat of indirect conflict spiraling into something more direct. Unlike October 2023, when Hezbollah launched direct attacks on Israel once the Gaza conflict began, this time the party has signaled that its support for Iran will not translate into direct military engagement with the Jewish state, a nuance that could prevent one avenue of immediate escalation, but the overall risk remains.

Nuclear Ambitions and Pre-emptive Strikes

A central pillar of Israel’s concern regarding Iran is its nuclear program. Israel views a nuclear-armed Iran as an existential threat, and its doctrine of pre-emptive strikes against perceived threats has been a consistent feature of its security policy. This has led to covert operations, assassinations of Iranian nuclear scientists, and cyberattacks aimed at disrupting Iran’s nuclear facilities. The first is that Israel plans to hit the nuclear facilities harder as the war goes on, should direct conflict erupt, indicating that these sites would be primary targets.

Historically, President Donald Trump threatened Iran's nuclear program, and his administration's withdrawal from the Joint Comprehensive Plan of Action (JCPOA) further heightened tensions, pushing Iran to accelerate its nuclear activities. This backdrop of nuclear proliferation fears significantly raises the stakes of any potential direct confrontation, as Israel might see an opportunity to degrade Iran's nuclear capabilities if a wider conflict were to occur.

The Brink of Direct Conflict: April 2024 and Beyond

The events of April 2024 brought the long-simmering tensions to a boiling point, demonstrating just how close the region came to a full-blown war between Israel and Iran. Tensions ran high in April 2024 as Israel and Iran launched limited, but direct, attacks against each other. This period offered a chilling glimpse into what a wider conflict could entail.

Iran's Retaliation: Missile Barrages and Warnings

Following the Damascus embassy bombing, Iran vowed retaliation. As forecast, Iran launched nearly 200 ballistic missiles at Israel beginning around 12:30 p.m. This unprecedented direct missile and drone attack from Iranian soil marked a significant shift from proxy warfare. Iran fired missile barrages at Israel twice last year, first in April in response to the bombing of the Iranian embassy in Damascus, and a second, much larger barrage in October in response to the (presumably Gaza-related) events, showcasing a new willingness to directly target Israeli territory. With Iran’s firing of some 180 ballistic missiles at Israel overnight, the Middle East was again on the brink of what would be a costly, ruinous regional war.

While the sheer volume of the attack was alarming, the Israeli antimissile system, primarily the Iron Dome and Arrow systems, shot down almost all of them, preventing significant damage or casualties. This success highlighted Israel's robust defensive capabilities but did not diminish the gravity of Iran's direct assault.

Israel's Response: Strategic Strikes and Declarations

Israel's response to Iran's missile barrage was swift and targeted, yet carefully calibrated to avoid immediate further escalation. On the evening of June 12 (likely a typo in the data, referring to a specific retaliatory strike after April 2024), Israel launched a series of major strikes against Iran. The targets included Iranian nuclear facilities, missile sites, and multiple senior military and political officials. In a televised speech, Israeli Prime Minister Benjamin Netanyahu declared success, indicating that Israel had achieved its objectives in the limited response.

By killing Iran’s military leadership—including nearly its entire air command—Israel has demonstrated its capability to significantly weaken Iran's military infrastructure. This strategic targeting aims to degrade Iran's ability to wage war and deter future aggression, but it also carries the inherent risk of pushing the conflict into an unpredictable, broader phase.

Unpacking the Potential Military Scenarios

If Iran goes to war with Israel directly, the conflict would likely involve multiple domains, far exceeding the limited exchanges seen in April 2024. The military strategies would be complex, leveraging both conventional and unconventional warfare tactics.

An open conflict would undoubtedly begin with intensified air campaigns. Israel would likely initiate an air campaign against Iran's nuclear and military facilities, aiming to cripple its strategic capabilities. This would include strikes on missile sites, command and control centers, and critical infrastructure. Iran, in turn, would retaliate against Israeli targets with its extensive arsenal of ballistic and cruise missiles, potentially overwhelming Israel's air defense systems despite their proven effectiveness. The conflict would escalate with Iran retaliating against Israeli targets, potentially targeting civilian population centers as well as military bases.

Beyond missile exchanges, cyber warfare would play a crucial role. Both nations possess sophisticated cyber capabilities and have engaged in cyberattacks against each other's infrastructure in the past. A full-scale conflict would see intensified cyber assaults aimed at disrupting critical services, intelligence gathering, and military communications. Covert operations, including sabotage and targeted assassinations, would also likely increase, adding another layer of complexity and unpredictability to the battlefield.

The Regional Ripple Effect: Who Joins the Fray?

A direct war between Israel and Iran would not remain confined to their borders. The Middle East is a complex web of alliances and rivalries, and such a conflict would inevitably draw in other regional and global actors, creating a devastating ripple effect.

The role of Iran's proxies would be critical. While Hezbollah has signaled that its support for Iran will not translate into direct military engagement with the Jewish state in the same way it did during the Gaza conflict, this stance could shift dramatically if Iran itself were under direct, sustained attack. A full-scale war could compel Hezbollah to open a second front against Israel from Lebanon, potentially overwhelming Israel's defenses and stretching its military resources thin. Other Iranian-backed militias in Iraq, Syria, and Yemen could also launch attacks against Israeli or U.S. interests in the region, further broadening the conflict.

The United States' involvement would be a defining factor. The U.S. has backed Israel materially and militarily throughout their war on Gaza but has also urged its main regional ally not to take rash actions that raise tensions with Iran and their allies. However, if Iran goes to war with Israel directly, particularly if U.S. assets or personnel in the region were targeted, the possibility of direct U.S. military involvement would become very real. President Donald Trump has hinted, suggesting even, that the United States might get directly involved in the ongoing conflict between Israel and Iran. This prospect is not limited to the Trump era; any U.S. administration would face immense pressure to protect its allies and interests. U.S. Senator Tim Kaine introduced a bill to curb Trump’s power to go to war with Iran, reflecting concerns about unchecked executive authority in such a volatile scenario. Foreign policy hawks, however, often call on the U.S. to join Israel in attacking Iran, underscoring the divided opinions within Washington.

Other regional powers, such as Saudi Arabia and the UAE, while often wary of Iran, would also face immense pressure to choose sides or navigate the conflict carefully. Their reactions could further destabilize the region, potentially leading to new alliances or deepening existing rifts.

Global Economic Fallout: Oil, Inflation, and Markets

The economic consequences of a war between Israel and Iran would be catastrophic on a global scale. The Middle East is the world's primary oil-producing region, and any major conflict there would inevitably disrupt global energy markets.

The price of oil and gasoline would skyrocket. Even the threat of conflict causes price volatility, but actual hostilities would severely restrict supply routes, particularly through the Strait of Hormuz, a critical chokepoint for global oil shipments. Such a surge in oil prices would have immediate and severe repercussions for economies worldwide. For context, during the first few months of the Trump presidency, the price of oil and gasoline fell, which was a key reason inflation dropped to 2.4% over the past 12 months. A reversal of this trend due to war would send inflation soaring, impacting consumer purchasing power and business costs globally.

Beyond energy, global supply chains, already strained by recent crises, would face unprecedented disruption. Shipping costs would escalate, and the availability of goods would be impacted, leading to further inflationary pressures and potential economic recessions in major economies. Financial markets would react with extreme volatility, as investor confidence plummets amidst the uncertainty and risk. The cost of such a ruinous regional war would be measured not only in lives but in trillions of dollars of economic damage.

Humanitarian Crisis and Civilian Toll

The human cost of a direct war between Israel and Iran would be immense. Both nations possess significant military capabilities, and any sustained conflict would result in widespread destruction and a severe humanitarian crisis.

Civilian populations would bear the brunt of the conflict. Extensive bombing campaigns, missile strikes, and potential ground operations would lead to massive displacement and a surge in refugees. Millions could be forced to flee their homes, straining humanitarian aid organizations and neighboring countries. Infrastructure, including hospitals, schools, power grids, and water treatment facilities, would be severely damaged or destroyed, exacerbating the humanitarian crisis and making recovery incredibly challenging.

The psychological toll on civilians, particularly children, would be profound and long-lasting. The loss of life, injury, and trauma would leave deep scars on generations. The sheer scale of potential casualties and the long-term health implications from environmental damage and lack of basic services would be devastating, far surpassing anything seen in recent regional conflicts.

Diplomatic Pathways and International Pressure

Given the dire consequences of a direct war, international efforts to de-escalate tensions and find diplomatic solutions would be paramount. The global community, including the United Nations, major powers like China and Russia, and European nations, would likely intensify diplomatic pressure on both sides to prevent further escalation.

Mediation efforts, back-channel negotiations, and multilateral dialogues would become critical. The focus would be on establishing ceasefires, creating de-escalation mechanisms, and addressing the underlying grievances that fuel the conflict. Sanctions and diplomatic isolation could be used as tools to compel adherence to international norms and prevent further aggression. The role of international law and institutions would be tested, as the world grapples with preventing a regional catastrophe with global ramifications.

However, the deep mistrust and ideological animosity between Iran and Israel make diplomatic breakthroughs incredibly challenging. Each side views the other as an existential threat, complicating any efforts towards reconciliation or even sustained de-escalation. The international community would need to present a united front and offer credible pathways for both security and de-escalation, which has proven difficult in the past.

Navigating the Future: Preventing a Regional Catastrophe

The possibility of open warfare between Israel and Iran is a real possibility again, a stark reminder of the volatile nature of the Middle East. Preventing this catastrophic outcome requires a multi-pronged approach that goes beyond immediate crisis management. It necessitates sustained diplomatic engagement, robust deterrence, and a clear understanding of red lines by all parties involved.

For Israel, maintaining its defensive capabilities, including its anti-missile systems, is crucial. Its ability to intercept nearly all of Iran's 200 ballistic missiles during the April 2024 incident demonstrated the effectiveness of these systems in preventing widespread damage. However, relying solely on defense is not a long-term solution. Strategic clarity and calibrated responses are essential to avoid unintended escalation.

For Iran, a re-evaluation of its regional strategy and proxy network might be necessary to avoid provoking further direct confrontation. While it seeks to project power and influence, the costs of a direct war with Israel, especially with potential U.S. involvement, would be ruinous for its economy and stability.

The international community, particularly the United States, plays a vital role in de-escalation. The U.S. has a delicate balancing act: supporting its ally Israel while simultaneously urging restraint and preventing a wider conflict that would destabilize global energy markets and security. This involves continuous communication with both Jerusalem and Tehran, directly or indirectly, to manage expectations and prevent miscalculations.

Conclusion

The specter of a direct war between Israel and Iran represents one of the most dangerous geopolitical flashpoints of our time. While fortunately, direct conflict appears unlikely at any given moment, the underlying tensions and recent escalations underscore the ever-present risk. The potential consequences—from regional devastation and a massive humanitarian crisis to global economic shocks and widespread instability—are too severe to contemplate lightly. The events of April 2024 served as a stark warning, showing just how close the Middle East came to a costly, ruinous regional war.

Preventing such a catastrophe demands continuous, concerted efforts from all stakeholders. Diplomacy, deterrence, and a commitment to de-escalation must prevail over the impulses of retaliation and escalation. The world watches with bated breath, hoping that cooler heads will prevail and that the path toward a more stable and peaceful future for the Middle East can be found.
