Executive Summary

The US-Israeli military campaign against Iran, now in its third week since initiation on 28 February 2026, continues to escalate with sustained airstrikes on key Iranian infrastructure, including oil refineries in Tehran and the city of Hamadan, as well as civilian sites like a Red Crescent clinic. Iranian retaliatory actions have intensified, featuring drone and missile strikes on UAE targets such as Dubai International Airport, causing flight suspensions and fires, and interceptions by Saudi defenses of 37 drones. Hezbollah has conducted missile attacks on Israeli positions in northern Israel and southern Lebanon, where Israeli counterstrikes have resulted in at least 10 fatalities. The closure of the Strait of Hormuz has halted all ship traffic, driving Brent crude prices above $106 per barrel and prompting global energy disruptions, including Japan's release of strategic reserves. Diplomatic efforts by President Trump to form a multinational coalition for naval escorts in the Strait of Hormuz have met resistance, with allies including Japan, Australia, Britain, and France declining deployments. Iran has deepened military ties with Russia and China, while rejecting ceasefire overtures and warning of fabricated plots to blame Tehran for escalated attacks. Humanitarian concerns mount, with hundreds arrested in Iran for alleged espionage, widespread protests in London and calls at the Oscars 2026 for ending the conflict, and environmental damage from strikes on fuel facilities. US officials anticipate the war could extend 4-6 weeks, with potential Iranian retention of nuclear fuel as leverage.

Threat Assessment

HIGH
75

The conflict remains at high threat level due to Iran's demonstrated asymmetric warfare capabilities, including advanced Sejjil missiles and drone swarms targeting critical Gulf infrastructure, which could expand to US bases in Iraq and Syria. Closure of the Strait of Hormuz poses severe economic risks, with oil disruptions threatening global recession; retaliatory strikes on civilian sites like Dubai Airport indicate willingness for escalation. Diplomatic isolation of US efforts, coupled with Iran's alliances with Russia and China, heightens prospects for proxy intensification via Hezbollah and potential cyber or terrorist operations. Iranian warnings of fabricated 9/11-style plots suggest information warfare to justify further actions. US forces face elevated risks from missile barrages, with shortages in allied munitions (e.g., French Rafale missiles) straining defenses. No immediate nuclear escalation, but retention of nuclear fuel as leverage warrants close monitoring.

Theater Updates

3 theaters · 2 active

Iranian Mainland

ACTIVE
  • US-Israeli airstrikes damage Tehran oil refinery, Red Crescent clinic, and Hamadan city, causing environmental contamination and civilian casualties.
  • Iran launches Sejjil 'dancing missiles' for the first time and deploys kamikaze drones against regional targets; reports indicate restraint on newer missile stockpiles.

Strait of Hormuz and Arabian Gulf

CONTESTED
  • Ship traffic through Strait of Hormuz drops to zero; oil prices surge past $106/barrel amid stalled US coalition efforts for naval protection.
  • Iranian drone strikes ignite fires at Dubai International Airport fuel terminal, suspending flights; UAE and Saudi Arabia intercept incoming threats.

Lebanon-Israel Border

ACTIVE
  • Hezbollah missile strikes hit Israeli tank, bulldozer, and Meron airbase; Israeli airstrikes in southern Lebanon kill 10, including in Qatrani and Majdal Selm.
  • UNIFIL peacekeepers fired upon during patrols with no injuries; additional strikes reported in Bekaa Valley.

Key Events

5 significant

Iranian Drone Assault on Dubai Airport

Disrupts major global aviation hub and Gulf energy logistics, signaling Iran's capability to project asymmetric threats beyond its borders and complicating US efforts to isolate Tehran.

Strait of Hormuz Closure and Oil Price Spike

Total halt in shipping exacerbates global energy crisis, pressuring economies worldwide and forcing US allies to confront dependency on the waterway, potentially fracturing coalition unity.

Allied Refusals to Join Hormuz Naval Coalition

Rejections by Japan, Australia, Britain, and others undermine Trump's strategy, risking US overextension and emboldening Iran to prolong the standoff.

Iran Announces Military Cooperation with Russia and China

Enhances Tehran's defensive posture through potential technology transfers and intelligence sharing, raising risks of broader great-power involvement in the conflict.

Hezbollah Escalates Cross-Border Attacks

Links Iran proxy actions to Lebanese theater, stretching Israeli resources and increasing chances of multi-front escalation involving US assets.

24-48 Hour Forecast

Over the next 24-48 hours, expect continued Iranian drone and missile salvos against Gulf targets, potentially targeting Saudi oil facilities to exploit allied hesitancy. US-Israeli airstrikes may intensify on Iranian command nodes to degrade launch capabilities. Trump's coalition push could yield partial commitments from smaller allies, but full Hormuz reopening remains unlikely without direct US naval action, sustaining oil prices above $105/barrel. Hezbollah activities along Lebanon border will persist, with risk of UNIFIL incidents drawing international scrutiny. Diplomatic channels may see backchannel talks, but Tehran's rejection of ceasefires points to prolonged attrition; monitor for Russian/Chinese material support to Iran.
