Major offensive by United States and Israel on Iran escalates Middle East conflict

KATHMANDU: A significant military campaign involving the United States and Israel was launched against the Islamic Republic of Iran, marking one of the most serious escalations in the long-standing regional tensions. The operation, which Israeli officials refer to as Operation Lion’s Roar, reportedly involved coordinated strikes on Iranian military, nuclear, and infrastructure targets across Tehran and other urban centres.

According to multiple international news agencies, airstrikes hit Tehran and other Iranian territories while the Iranian leadership was reported as a primary target. Israeli Prime Minister Benjamin Netanyahu stated that there were indications Iran’s Supreme Leader Ayatollah Ali Khamenei may have been killed, though these claims have not been independently verified and Iranian officials have neither confirmed nor refuted this publicly at the time of reporting.

Iran’s Response and Regional Retaliation

In immediate response, Tehran vowed retaliatory actions against both Israeli and U.S. interests in the region. Explosions were reported across multiple Gulf states hosting U.S. military assets, including Bahrain, and missiles were said to have been fired back at U.S. bases and neighbouring allied infrastructure—raising regional security fears.

Iranian authorities condemned the strikes as a violation of international law and have declared that “all American and Israeli assets and interests in the Middle East have become legitimate targets.”

International Reaction

Global leaders expressed alarm at the sharp escalation. Russia condemned the joint U.S.–Israeli attacks as “unprovoked aggression” and called for an immediate halt to hostilities, pressing for diplomatic solutions through the United Nations. Western governments similarly urged restraint, calling on all parties to respect international law and protect civilians. United Nations Secretary-General António Guterres warned that the conflict “undermines international peace and security” and could trigger a wider regional war.

Context: Long-Standing Tensions and Strategic Motives

This dramatic escalation follows years of geopolitical friction between Israel and Iran over Tehran’s nuclear program, regional influence through proxy militias, and ballistic missile capabilities. Diplomatic efforts between the U.S. and Iran in early 2026, aimed at limiting Iranian nuclear ambitions, reportedly broke down, leaving military options perceived by Washington and Tel Aviv as necessary to neutralise what they described as an “existential threat.”

A similar conflict erupted previously in mid-2025, culminating in a ceasefire known as the Twelve-Day War, which was mediated partly by the United States and Qatar. That conflict caused major damage to infrastructure, energy exports, and heightened mistrust on both sides, but ultimately ended without a decisive victory for either side.

Consequences and Potential Aftermath

1. Expanded Regional Conflict Risk

Analysts warn that the current offensive could drag multiple states into direct or proxy confrontations. Iran’s alliances with groups such as Hezbollah in Lebanon, militias in Iraq and Syria, and support networks in Yemen raise the likelihood of broader clashes. Countries in the Gulf are reportedly bracing for retaliation on their territory or against foreign military bases.

2. Global Economic Fallout

Energy markets have already shown acute volatility. The Strait of Hormuz, a critical chokepoint for roughly 20% of global oil supply, faces the threat of closure if Iran seeks to disrupt shipping lanes. Analysts estimate that even temporary shutdowns could cause sharp spikes in oil prices, fuel inflationary pressures worldwide, and slow global growth. U.S. inflation could rise significantly, forcing monetary tightening, while supply chain disruptions could affect everything from manufacturing to agriculture.

3. Humanitarian Impact

Civilians in both Iran and Israel face rising casualties and displacement as airstrikes and retaliatory actions continue. Infrastructure damage, interruption of basic services, and the closure of international transport hubs have already disrupted civilian life and labour markets across the region. International humanitarian agencies have sounded early warnings of a widening crisis if hostilities persist.

4. Diplomatic and Strategic Repercussions

The conflict is straining U.S. diplomatic relations with certain global partners and complicating efforts to stabilise other geopolitical flashpoints. Russia’s sharp criticism and call for a U.N. Security Council session highlight deep geopolitical divides at a time when cooperative diplomacy is urgently needed. Calls for restraint have come from the European Union and other blocs emphasising respect for international law and protection of noncombatants.

Outlook

While immediate combat dynamics remain fluid, experts agree that the conflict could reshape Middle Eastern security structures and global energy trade. Further escalation without robust diplomatic intervention may see the confrontation expand beyond Iran and Israel to involve proxy battles across the region, with far-reaching economic and humanitarian consequences. U.N. and international diplomatic engagement will be critical to contain the crisis and avoid broader war.
