The conflict between Israel, the United States, and Iran has shifted dramatically from years of incremental tensions, proxy skirmishes, and diplomatic posturing into a full-blown military confrontation in 2025–2026. Rooted in deep historical rivalries and geopolitical rivalries, the latest chapter escalated into direct military strikes, counterstrikes, global condemnations, and fears of a region-wide war.
Historical Roots of the Israel–Iran Rivalry
Relations between Israel and the Islamic Republic of Iran have never been normal since the 1979 Iranian Revolution. Before the revolution, Israel and Iran maintained cordial economic and strategic ties — bound by mutual concerns about Arab nationalism and Soviet influence. However, with the rise of the Islamic Republic under Ayatollah Ruhollah Khomeini, Tehran adopted an ideology hostile to Israel’s very existence, branding the Jewish state as an “illegitimate” entity and promising unwavering support for its enemies, including militant groups like Hezbollah and Hamas.
For decades, the rivalry was indirect — fought largely through proxy forces and diplomatic pressure rather than direct confrontation. Iran’s support for Hezbollah in Lebanon, its backing of Hamas in Gaza, and its assistance to various militias in Syria and Iraq furnished Tehran with a network of influence that could menace Israeli security without engaging in conventional warfare.
This dynamic entrenched a binary of opposing visions: Israel, backed staunchly by the United States, portrayed Iran as a strategic existential threat, while Iran presented itself as the defiant bulwark against Western influence and regional domination. Complicating the rivalry was Iran’s controversial nuclear program, which suspected Western intelligence agencies argued aimed to produce weapons-grade material capable of sustaining a nuclear arsenal.
From Diplomacy to Confrontation
Throughout the 2000s and 2010s, tensions periodically spiked — from Iranian nuclear negotiations to proxy clashes in Syria. A noteworthy episode occurred with the 2015 nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), which aimed to limit Iran’s nuclear capabilities in exchange for sanctions relief. While Israel criticized the agreement as insufficient, the United States under President Barack Obama pursued it as a stabilizing measure.
That changed under U.S. President Donald Trump, who withdrew the U.S. from the deal in 2018 and reimposed sweeping sanctions on Iran. Teheran responded with an acceleration of its nuclear program and escalating hostile actions, including missile strikes on U.S. bases in the region and support for attacks on U.S. forces by Iran-aligned militias.
Between 2023 and 2024, the conflict landscape shifted yet again with Israel’s large-scale campaign against Hamasfollowing the October 7, 2023 attack. Iran’s role as a financial and military backer of Hamas and Hezbollah deepened Israel’s perception of an encircling threat.
The 2025 Israel–Iran War Era
June 2025: A Pivotal Escalation
The first major direct confrontation between Israel and Iran erupted in June 2025. In a dramatic escalation, Israel launched an aerial campaign — known internally as Operation Rising Lion — that included coordinated airstrikes deep inside Iranian territory. According to Israeli military sources, the strikes targeted nuclear, missile, and military infrastructure — including missile launchers, air defense batteries, and command facilities. Intelligence assets reportedly allowed Israel to penetrate and degrade Iranian defenses far more effectively than past operations.
Iran responded with a large missile and drone offensive, reportedly launching hundreds of ballistic missiles and drones toward Israeli cities. While Israel’s defensive systems, such as its Iron Dome, intercepted most incoming threats, the missile attack signaled Iran’s willingness to transition from proxy warfare to direct conventional retaliation.
The June 2025 conflict ended in a ceasefire after 12 days, brokered by U.S. diplomatic efforts. It was the first time since the revolution that Israel and Iran experienced large-scale direct combat, resulting in significant casualties and infrastructure damage on both sides.
US Involvement Intensifies
While Israel was the primary actor on the offensive front, the United States played an increasingly direct role. In late June 2025, the U.S. conducted airstrikes on key Iranian nuclear sites such as Natanz, Fordow, and Isfahan, which the Pentagon described as severely degrading Tehran’s nuclear capabilities — though the full extent remained a subject of dispute.
This marked the first targeted U.S. military action inside Iran since the assassination of Iranian general Qasem Soleimaniin 2020. Supporters in the U.S. political establishment, particularly among hardliners, lauded the offensive for setting back the Iranian program and signaling deterrent resolve. However, critics from across the political spectrum raised constitutional and strategic concerns about America’s deeper involvement.
The 2026 Theater: Direct Attack and Counterstrike
By early 2026, nuclear negotiation efforts between the United States and Iran appeared to gain some traction. Talks mediated by Oman sought to find a diplomatic path forward on Iran’s nuclear ambitions. However, on February 28, 2026, these hopes were shattered by a sudden and dramatic escalation.
Operation Lion’s Roar: Joint US–Israeli Strikes
On that day, Israel launched a massive air campaign — named Operation Lion’s Roar — striking hundreds of targets across Iran, including urban centers and military facilities. Multiple reports indicate that this was one of the most extensive aerial campaigns in the history of the Israeli Air Force, coordinated with American military assets under a joint effort described by U.S. leadership as Operation Epic Fury.
According to defense reports, more than 200 Israeli aircraft took part, targeting key air defenses and missile launch sites within Iran. These strikes were described by Israeli leaders as necessary to degrade Tehran’s offensive capabilities and neutralize perceived imminent threats.
The attack reportedly struck deep into urban areas, leading to extensive civilian casualties — including at least 85 pupils killed when an elementary school in Minab, Hormozgan Province was hit by a cruise missile. Iranian officials condemned the incident as a war crime and demanded international intervention.
Iran’s Retaliation
Iran responded swiftly, launching a barrage of ballistic missiles and drones targeting both Israeli territory and U.S. military bases across the Middle East — including bases in Qatar, Kuwait, the United Arab Emirates, Bahrain, Jordan, and Iraq. Iranian authorities declared all U.S. and Israeli assets in the region to be legitimate targets in what they described as a defensive campaign against aggression.
The strikes resulted in damage in multiple Gulf states, including an attack on the headquarters of the U.S. Navy’s Fifth Fleet in Bahrain, prompting widespread condemnation from Gulf governments that decried Iran’s violations of their sovereignty.
Global and Diplomatic Fallout
The conflict drew intense global attention and divergent international reactions:
- Russia condemned the U.S.–Israeli strikes as an unprovoked act of aggression, warning that the conflict could lead to humanitarian and radiological disaster. Moscow offered to mediate peace efforts, stressing its historical ties with Tehran, even while its ties with Washington showed signs of cautious engagement. (AP News)
- United Nations officials called for an immediate cessation of hostilities, emphasizing the grave risks of an uncontrollable regional war and urging diplomatic solutions.
- Numerous countries condemned the strikes for violating international law, while others backed Israel’s right to defend itself.
The resulting tensions have rippled beyond geopolitics; oil markets experienced volatility, with prices rising sharply as traders priced in risks of supply disruptions through key routes like the Strait of Hormuz. Analysts warned that sustained conflict could impact global economic growth and inflation, especially in energy-dependent markets around the world.
Domestic Reactions Within the Nations
Israel
In Israel, the offensive garnered substantial political support across a broad spectrum of leaders, reinforcing a sense of existential urgency in public discourse. Surveys indicated widespread backing for action against Iran, seen by many as necessary for national survival and security. Military sirens, mass mobilizations, and civil defense measures underscored the tense atmosphere.
Iran
In Iran, the conflict has hardened public sentiment against perceived foreign aggression. Despite economic hardship and domestic protests that flared in late 2025 over economic conditions and governance, the government’s narrative emphasized unity against external enemies. Iran’s leadership vowed to continue its resistance, framing the war as a defense of sovereignty against Western and Israeli imperialism.
Broader Regional and Global Implications
The conflict has strained relations across the Middle East and beyond. Gulf states hosting U.S. military assets condemned Iranian strikes as violations of their sovereignty, while Iran sought support from non-aligned nations and sympathetic states. Beyond the region, the conflict has affected diplomatic alignments, economic markets, and global security calculations.
Economists warn of potential higher energy prices, supply chain risks, and inflationary pressures if instability persists or expands into broader regional war. Financial markets have reacted to geopolitical risk with increased volatility in commodities, defense stocks, and safe-haven assets like gold.
Prospects for the Future
As of early 2026, the conflict remains highly volatile. The direct military engagement between Israel, the United States, and Iran marks a watershed in Middle Eastern geopolitics — transforming latent tensions into overt conflict with unpredictable consequences.
Several paths lie ahead:
- Extended Military Conflict: Continued hostilities could deepen the war, possibly drawing in regional actors such as Iran-aligned militias, Hezbollah, or even states like Saudi Arabia and Turkey, depending on geopolitical calculations.
- Diplomatic Ceasefire: Despite the ferocity of current operations, international pressure and mediated negotiations could still yield a ceasefire, though the terms and durability remain uncertain.
- Regime and Regional Changes: Prolonged conflict could impact Iran’s internal stability, Israel’s domestic politics, and the strategic positioning of global powers like the U.S., Russia, and China in the Middle East.
Regardless of the immediate trajectory, the crisis underscores the fragility of regional stability and the complex interplay of military power, diplomacy, and national interests in a region long beset by conflict.
