The tensions between Iran, the United States, and Israel escalated into one of the most dangerous crises in recent Middle Eastern history. A series of coordinated military strikes by the U.S. and Israel against Iran — including attacks on key regime figures and strategic military infrastructure — triggered a fierce Iranian retaliation, broadening the conflict beyond previous flashpoints and raising the specter of a wider regional war with global consequences.

Historical Roots of the Conflict

The roots of the Iran-U.S.-Israel standoff extend back decades. Before the 1979 Iranian Revolution, Tehran and Jerusalem maintained relatively cordial relations. After the revolution, Iran’s new Islamic Republic adopted a staunchly anti-Western, anti-Israeli posture, branding the United States as the “Great Satan” and Israel as the “Little Satan.”  This ideological transformation set the stage for deep-seated mistrust and periodic confrontations.

Over subsequent decades, disputes have centred on Iran’s nuclear program, its support for regional proxy forces (including Hezbollah and various militia groups), and Washington’s security commitments to Israel and Gulf allies. U.S. withdrawal from the 2015 nuclear deal (Joint Comprehensive Plan of Action) in 2018 and the “maximum pressure” sanctions campaign that followed severely strained relations, while repeated Israeli strikes on Iranian-linked targets across the region heightened hostilities.

The 2026 Escalation: From Buildup to War

By early 2026, diplomatic efforts to revive nuclear negotiations had faltered. Despite talks in Muscat and Geneva aimed at limiting Iran’s uranium enrichment and missile capabilities, U.S. leaders publicly signalled frustration with Tehran’s pace and scope of concessions, deploying additional U.S. military assets to the Middle East as a deterrent.

On 28 February 2026, the United States and Israel launched a joint military offensive against Iran, codenamed Operation Lion’s Roar by Jerusalem and Operation Epic Fury by Washington. The strikes targeted strategic military installations, command centres, and senior leadership positions. According to multiple reports, the Iranian Supreme Leader Ali Khamenei was reportedly killed, an unprecedented blow to the Islamic Republic’s political hierarchy.

The offensive marked a sharp escalation — one framed by U.S. authorities as necessary to degrade Iran’s nuclear ambitions and long-range missile capabilities, and to pre-empt what was portrayed as an imminent threat to U.S. forces, regional partners, and Israel’s security.

Iran’s Attacks on Neighboring Countries

As the conflict escalated in 2026, Iran’s retaliation extended beyond direct strikes on Israel and U.S. forces. Tehran reportedly launched missile and drone attacks targeting American military bases and strategic facilities located in several neighboring Middle Eastern countries. This widened the conflict from a trilateral confrontation into a broader regional crisis.

Countries Affected

1. Israel:
   Iran launched ballistic missiles and armed drones toward Israeli territory, targeting military installations and urban areas. Israel’s air defense systems intercepted many projectiles, but the attacks significantly heightened tensions.
2. United Arab Emirates (UAE):
   Cities such as Abu Dhabi and Dubai were placed on high alert after missile threats and drone activity were detected. Strategic infrastructure, including energy and transport facilities, faced elevated risk.
3. Qatar:
   Iranian missiles reportedly targeted areas near U.S. military installations in Qatar, including locations associated with American air operations. Airspace restrictions and emergency security measures were implemented.
4. Kuwait:
   Missile alerts were issued near areas hosting American military assets. Defensive systems were activated to intercept incoming threats.
5. Bahrain:
   Home to the U.S. Fifth Fleet headquarters, Bahrain became a sensitive target zone. Security was intensified following missile and drone threats linked to Iranian retaliation.
6. Saudi Arabia:
   Energy infrastructure, including oil processing facilities, faced potential threats. Given Saudi Arabia’s strategic oil exports, any attack risked major global energy disruption.
7. Jordan:
   Though not a primary combatant, Jordan strengthened its air defenses amid regional missile activity and rising security concerns.

Iran’s Retaliation and Regional Spread

Iran’s response was swift and multifaceted. Tehran launched missiles and drones against Israeli territory, U.S. military bases across the Gulf, and vital infrastructure in neighbouring Gulf Arab states. Iranian proxies and Iranian-aligned militias — including Hezbollah in Lebanon and groups in Iraq — joined the confrontation, widening the scope of hostilities.

Reports indicate attacks on U.S. and Gulf facilities in Qatar, Kuwait, the UAE, Bahrain, and Jordan, as well as retaliatory strikes on Israel. The conflict quickly transcended conventional battlefields, with strategic chokepoints such as the Strait of Hormuz effectively disrupted, threatening global oil shipments.

Saudi Arabia and other Gulf states condemned Iranian attacks on their territories, summoning envoys and signalling diplomatic fractures across the region.

Strategic Drivers and Aims

Understanding the geopolitical logic of the conflict requires analysing the objectives of the main actors:

1. The United States:
For Washington, the confrontation is not only about containment of Iran’s nuclear program but also about reaffirming American strategic dominance in the Middle East. The Trump administration’s strategy has embraced regime change rhetoric, intensified military pressure, and a push to dismantle Iran’s regional network of influence. Deployments of carrier strike groups and additional forces underscore a desire to project power and deter broader escalation, even as they paradoxically fuel it.

2. Israel:
Israel’s strategic calculus centres on existential threats. Tehran’s missile arsenal, drone capabilities, and backing of militant groups pose direct risks to Israeli security. Repeated strikes on Iranian targets reflect an Israeli priority to pre-emptively degrade Tehran’s offensive capabilities and remove leadership figures seen as drivers of aggression.

3. Iran:
For Tehran, the conflict is a defence of sovereignty and regime survival. The Islamic Republic has consistently framed Western pressure and Israeli hostility as existential threats linked to broader historical grievances. Retaliatory attacks are intended to demonstrate Iran’s capacity to strike both in depth and across multiple fronts, maintaining deterrence and domestic legitimacy.

Human and Structural Costs

The immediate toll of the conflict has been high. Casualty figures on all sides include military personnel and civilians; infrastructure damage is extensive, and major cities have come under bombardment. Reports — though varying by source — describe explosions in Tehran and other Iranian cities, as well as impacts in Israel and several Gulf states.

Beyond the battlefield, economic shocks are reverberating globally. Disruptions at the Strait of Hormuz — through which a significant proportion of the world’s oil transits — have sent energy markets into volatility. Countries dependent on Gulf energy exports are adjusting forecasts and strategic stockpiles in response.

Global and Geopolitical Implications

The conflict’s implications extend far beyond the Middle East.

• Energy Security: Disruptions in oil supplies risk prolonged market instability, with price surges affecting global inflation and supply chains.
• Diplomacy and Alliances: The crisis tests existing alliances and could reshape alignments. While Western powers have largely backed the U.S. response, others — including China and Russia — have adopted cautious diplomatic positions, signaling long-term strategic recalibrations.
• Regional Fragmentation: The war underscores fractures among Middle Eastern states, with some Gulf nations aligning more closely with U.S. policy, while others seek neutrality or hedging strategies to avoid being drawn into battle.
• Nuclear Non-Proliferation: The conflict complicates global efforts to manage nuclear proliferation. Iran’s nuclear ambitions — historically central to regional security debates — could be either accelerated or constrained depending on diplomatic outcomes and internal Iranian political dynamics.

Paths to De-Escalation and Peace

Despite the scale of the crisis, pathways to de-escalation remain possible but challenging. Historical precedence suggests that sustained diplomacy, mediated negotiations, and multilateral frameworks such as renewed nuclear talks under international supervision could eventually reduce tensions. However, the current clash has deepened mistrust and expanded the list of actors involved, making swift breakthroughs less likely without significant compromise.

International organisations can play a role by facilitating ceasefires, humanitarian aid, and longer-term peace processes, but these efforts require buy-in from all major parties — something not yet firmly in evidence.

The Iran-U.S.-Israel conflict in 2026 represents a pivotal moment in Middle Eastern geopolitics. Born from decades of ideological conflict, strategic rivalry, and regional power struggles, the confrontation has quickly escalated into a wide-ranging war with profound human, economic, and geopolitical consequences. Whether it ultimately gives way to negotiation, stalemate, or further escalation depends on strategic choices by the key actors and the capacity of the international community to mediate and manage the crisis.

In a world of interconnected power dynamics, the outcome of this conflict will shape regional and global politics for years to come.
