The U.S.-Israeli military operation dubbed "Epic Fury" entered its fourth day as Iran's Revolutionary Guard formally announced the closure of the Strait of Hormuz, warning it will fire on any vessels attempting to pass. What began as a surgical strike to eliminate Iranian Supreme Leader Ayatollah Ali Khamenei has rapidly escalated into a high-stakes regional conflict, threatening to shock the global economy and upend Middle Eastern geopolitics.
Choking the Global Economic Lifeline
To understand the conflict's potential impact on global markets, observers are looking closely at the Strait of Hormuz. Situated between Oman and Iran, the waterway connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest point, the strait spans just 33 kilometers (21 miles), compressing shipping lanes for massive oil tankers into a mere 3-kilometer (2-mile) corridor.
According to the global energy analytics firm Vortexa, more than 20 million barrels of crude oil, condensate, and fuel products transit the strait daily, accounting for nearly 20% of global petroleum consumption.
Qatar, the world's largest exporter of liquefied natural gas (LNG), relies almost exclusively on the strait. Reports indicate that QatarEnergy has already been forced to suspend LNG production.
In early Asian trading, U.S. crude oil futures fell 1% as market panic spread and regional maritime traffic ground to a virtual halt.
Iran's threats have materialized into immediate kinetic action. Shipping management companies confirmed that suspected missiles or drones struck the Marshall Islands-flagged product tanker MKD VYOM off the Omani coast, killing one crew member. Two other tankers sustained damage in separate attacks.
Beyond overt strikes, U.S. intelligence estimates Iran has stockpiled up to 6,000 naval mines—including floating, magnetic, bottom, and moored variants. Maritime risk intelligence firm Dryad Global noted that Iran's coastal geographic advantage enables rapid, untraceable mining operations using fast attack craft or submarines. While large-scale mining has not yet been reported, the asymmetric threat alone has deterred global shipping companies.
Military Casualties and Friendly Fire
The chaotic airspace over the Middle East has resulted in tragic losses and operational blunders.
U.S. Central Command confirmed that during Iran's retaliatory strikes against Kuwait, Kuwaiti air defense systems mistakenly engaged and shot down three U.S. Air Force F-15E aircraft. All six crew members successfully ejected and were safely recovered. However, the incident exposed severe vulnerabilities in allied identification systems under intense air defense pressure.
Not all U.S. forces survived the weekend's escalation. Six U.S. service members were killed during Iran's retaliation against Kuwait, marking the first major American casualties since the conflict began.
In response, the U.S. military claims to have struck over 1,250 targets inside Iran and destroyed 11 Iranian naval vessels. Satellite imagery shows severe damage to Iran's Choqa Balk-e Alireza drone facility.
Regional Spillover and Civilian Toll
Iran has actively expanded the conflict footprint, targeting U.S. allies across the Arabian Peninsula:
A Saudi Defense Ministry spokesman confirmed that two drones attacked the Ras Tanura refinery on the eastern coast. While intercepted, falling debris sparked fires at the critical Saudi Aramco facility. Furthermore, the U.S. Embassy in Riyadh caught fire following explosions in the capital.
The UAE Defense Ministry reported its air defenses were actively responding to a fresh wave of Iranian ballistic missiles.
Facing rapidly deteriorating security conditions, the U.S. State Department has urged American citizens to immediately evacuate more than a dozen Middle Eastern countries.
Meanwhile, the civilian death toll is mounting. According to Iranian state media, a girls' elementary school in the southern town of Minab was bombed on the first day of airstrikes, killing over 160 people. The tragedy drew immediate condemnation from UNESCO and Nobel Peace Prize laureate Malala Yousafzai.
The U.S. government quickly distanced itself from the allegations. Secretary of State Marco Rubio stated the U.S. "would never deliberately target schools." Deflecting to the Pentagon, Rubio added, "If that was our strike, the War Department will investigate it; I suggest you ask them." U.S. Central Command stated it is "investigating" civilian casualties but has provided no clear accounting.
In downtown Tehran, Iranian media reported massive explosions near the headquarters of the state broadcaster, IRIB, shortly after Israeli forces issued evacuation warnings. Israel subsequently confirmed targeting the building, while simultaneously announcing strikes on Hezbollah command centers in Beirut.
Tehran's Power Vacuum and U.S. Domestic Fallout
A major uncertainty hinges on the upheaval within Iran's regime. Israel claims its military operations over the past two years have systematically eliminated senior Iranian military officials and weakened proxy forces. With the latest strikes killing Khamenei and other leaders, a massive power vacuum has emerged.
Iranian President Masoud Pezeshkian announced the formation of a temporary "Leadership Council"—comprising himself, the judiciary chief, and members of the Guardian Council—to assume the Supreme Leader's duties. The vacuum has also fueled speculation about whether the grandson of Iran's founding father, Ayatollah Ruhollah Khomeini, might return to the political spotlight.
For U.S. President Donald Trump, "Epic Fury" has evolved into a high-stakes political gamble. Trump stated the military operation could last four to five weeks, or longer, admitting the U.S. lacks a clear understanding of who currently controls Iran. Despite promising that U.S. forces will complete their mission "at any cost," domestic support is faltering.
A recent Reuters/Ipsos poll shows only 25% of Americans support attacking Iran—a dismal approval rating that poses significant risks for the Republican party ahead of November's midterm elections. （Related： The Navy Unit No One Talks About — And Can't Afford to Lose ｜ Latest ）
