Executive Summary

The US-Israel-Iran conflict, now entering its third week since initiation on 28 February 2026, has escalated into a multi-front confrontation with significant disruptions to global energy markets. Iranian drone and missile strikes have targeted key infrastructure, including multiple attacks on Dubai International Airport causing fires and operational suspensions, while US and Israeli forces conduct airstrikes on Iranian targets such as Hamadan and Tehran, resulting in civilian casualties and environmental damage. The Strait of Hormuz remains completely closed to commercial traffic for the first time since the war began, driving Brent crude prices above $106 per barrel and prompting warnings from US oil executives of an impending energy crisis. Diplomatic efforts are faltering as President Trump seeks an international coalition to escort tankers through the Strait, but key allies including the UK, Australia, France, and Japan have declined or delayed commitments, citing escalation risks. Hezbollah's missile attacks on Israeli positions in northern Israel and southern Lebanon have intensified cross-border fighting, with Israeli retaliatory strikes killing at least 10 in Lebanon and 13 in Gaza. Iranian officials reject ceasefire overtures, vowing prolonged resistance, while internal security measures include mass arrests of suspected spies. Protests against the war continue globally, with large demonstrations in London and calls for peace at the 2026 Oscars. US assessments indicate the conflict could last 4-6 weeks, with costs already exceeding $12 billion, underscoring strategic vulnerabilities in allied support and regional stability.

Threat Assessment

CRITICAL
95

The threat environment is at a critical juncture due to Iran's demonstrated asymmetric warfare capabilities, including drone swarms and precision missiles, which have successfully targeted high-value assets like Dubai Airport and US airbases in Iraq. The total closure of the Strait of Hormuz poses an existential risk to global energy security, with potential for Iranian mining or direct attacks on convoys amplifying disruptions. Allied hesitancy undermines US operational freedom, increasing reliance on unilateral actions that could provoke Iranian nuclear leverage or proxy escalations via Hezbollah and Houthis. Cyber and disinformation campaigns, including AI-generated fakes, further complicate command and control. Civilian impacts, including environmental damage in Iran and casualties in Lebanon/Gaza, heighten humanitarian risks and anti-US sentiment, while internal Iranian arrests suggest regime consolidation but also vulnerability to espionage. Overall, escalation to full naval confrontation or multi-theater expansion remains probable without de-escalation.

Theater Updates

4 theaters · 3 active

Strait of Hormuz / Persian Gulf

ACTIVE
  • Ship traffic through the Strait fell to zero on 15 March, halting all oil exports and causing Brent crude to surge to $106+ per barrel.
  • President Trump calls for warships from seven nations to form protective convoys, but UK, Australia, France, and Japan refuse or hesitate, increasing US isolation.
  • Iran continues shielding its own oil exports while choking regional flows, with Revolutionary Guard threatening attacks on any intervention forces.

Iran Mainland

CONTESTED
  • US-Israeli airstrikes hit Hamadan and Tehran fuel tanks, prompting Iranian accusations of environmental crimes and vows of retaliation.
  • Iran launches Sejjil missiles for the first time and deploys kamikaze drones against UAE targets; reports indicate use of older stockpiles so far.
  • Iranian authorities arrest over 500 individuals accused of spying for adversaries, including links to Israel-affiliated media.

Lebanon-Israel Border

ACTIVE
  • Hezbollah claims missile strikes on Israeli tanks, bases, and Meron air control, while Israeli airstrikes in southern Lebanon kill 10 civilians.
  • UNIFIL peacekeepers fired upon during patrols with no injuries; separate strikes hit Beirut suburbs and Bekaa Valley.
  • Israeli operations in Gaza kill 13, including children and a pregnant woman, amid ongoing Hezbollah-Israel exchanges.

Gulf States (UAE/Saudi Arabia/Iraq)

ACTIVE
  • Multiple Iranian drone strikes on Dubai International Airport ignite fuel tanks, suspending flights and causing fires.
  • Saudi Arabia intercepts 37 drones in 90 minutes targeting eastern oil infrastructure; US orders citizens to leave Iraq amid attacks on four airbases.
  • Iran denies involvement in Saudi attacks but warns of broader regional escalation.

Key Events

5 significant

Dubai Airport Drone Strikes

These attacks disrupt UAE's critical aviation hub, signaling Iran's capability to project asymmetric threats into Gulf allies, potentially deterring coalition formation and amplifying economic pressure on global trade.

Strait of Hormuz Closure

Complete halt of shipping for the first time exacerbates energy crisis, with oil prices spiking; failure to reopen risks prolonged global recession and forces US to reconsider unilateral actions like seizing Kharg Island.

Allied Refusal to Join Hormuz Coalition

Rejections from UK, Australia, France, and others isolate US strategy, weakening deterrence against Iran and straining NATO ties, as Trump warns of 'very bad future' for non-cooperative allies.

Hezbollah-Israel Escalation

Missile exchanges and Israeli strikes killing dozens open a northern front, diverting Israeli resources from Iran and risking broader regional war involving Lebanon.

Iranian Sejjil Missile Launch

First use of advanced 'dancing missile' demonstrates Iran's untapped arsenal, challenging US-Israeli air defenses and escalating the ballistic threat to regional bases.

24-48 Hour Forecast

Over the next 24-48 hours, expect continued Iranian drone and missile activity targeting Gulf infrastructure and US assets, with potential reprisal strikes on Tehran and southern Lebanon by US-Israeli forces. Oil prices may climb toward $110 per barrel amid sustained Hormuz closure, prompting emergency US diplomatic pushes for limited coalition contributions like UK minesweeping drones. Diplomatic talks with Iran are unlikely to yield breakthroughs, as Tehran rejects ceasefires; monitor for Trump announcements on Kharg Island seizure or delayed China summit. Hezbollah-Israel border clashes could intensify, risking UNIFIL incidents. No immediate de-escalation anticipated, with war duration projected at 4-6 weeks.
