Executive Summary

Confidence Level: Medium — Fog of war limits verification of early claims

On February 28, 2026, the United States and Israel launched a coordinated military campaign against Iran, marking the most significant military escalation in the Middle East since the 2003 invasion of Iraq. Israel designated its operation Operation Roaring Lion, while the US component operates under Operation Epic Fury. Verified [Source]

In the first 72 hours of the campaign, coalition forces conducted approximately 2,000 strikes against Iranian military infrastructure, command-and-control nodes, air defense systems, and leadership targets. The most consequential outcome of the opening salvo was the confirmed death of Supreme Leader Ayatollah Ali Khamenei, along with more than 40 senior IRGC and military commanders. Verified [Source]

Iran retaliated with ballistic missiles and drone swarms directed at Israel and multiple Gulf states, including the UAE, Qatar, Kuwait, Bahrain, Jordan, and Saudi Arabia. The retaliatory strikes resulted in at least 11 deaths in Israel, 6 US service members killed, and 8 fatalities across Gulf states. Iranian casualties stand at 787 or more, a figure that is expected to rise significantly. Verified [Source]

The IRGC issued a warning to all commercial and military vessels not to transit the Strait of Hormuz, effectively closing the waterway through which approximately 20% of the world's oil supply passes. Oil prices surged 13%, with Brent crude heading toward the $100 per barrel threshold. Verified [Source]

President Trump stated the war would last 4–5 weeks and that the strategic objective is regime change in Tehran, though administration officials have offered varying descriptions of US goals. Verified [Source]

International Reactions

China

Beijing condemned the strikes as a "grave violation of Iran's sovereignty" and stated it "strongly condemns" the military action. However, China has taken no concrete retaliatory steps beyond diplomatic protests. Beijing's primary concern centers on energy supply disruption, as Iran is a significant oil supplier to China.

Russia

Moscow called the strikes "unprovoked armed aggression" and summoned the US ambassador. Russia remains functionally unable to provide direct military assistance to Iran, given its ongoing commitments in Ukraine. Kremlin officials are also reportedly concerned about implications for their own air defense supply chains.

United Nations

An emergency UN Security Council session was convened. Secretary-General António Guterres stated the strikes "squandered the chance for diplomacy" and called for an immediate ceasefire. The US and likely the UK are expected to veto any binding resolution.

EU / NATO

European and NATO responses remain divided. The UK has expressed measured support for the US position, while France and Germany have called for restraint and a diplomatic off-ramp.
