The US military's own journals say the tools needed to reach Kharg Island do not adequately exist. Iran has been mining the approaches since March.

Key takeaway

The US has not fought through a contested minefield since 1991; Kharg requires it.

USNI Proceedings' April issue ran simultaneous articles on Hormuz amphibious options and what it called "The Crisis in Mine Countermeasures." War on the Rocks separately assessed that US MCM capability has "atrophied for years and is extremely limited" . The combined signal from the military's own publications: the tools needed for a Kharg operation do not adequately exist.

The USS Tripoli amphibious group (2,200 Marines, F-35Bs, 31st MEU) is in the area of operations. The USS Boxer (2,500 Marines, 11th MEU) is en route. Thirty A-10s and the 82nd Airborne are staged. But to reach Kharg Island, these ships must transit a 24-mile-wide strait against Iranian anti-ship missiles, Shaheds, fast boats, and mines. Iran has been mining Kharg's approaches since at least 26 March. The US has not fought through a contested minefield since 1991.

Deep Analysis

In plain English

Iran has planted sea mines around Kharg Island, its main oil export terminal, to stop US ships from reaching it. The US has two large groups of Marine assault ships heading toward the area carrying nearly 5,000 troops. But the US military's own professional journals published warnings this month that the US has nearly forgotten how to clear sea mines, having not done it in a contested environment since 1991. The ships are assembling for an operation the military's own experts say it cannot safely execute.

Deep Analysis
Root Causes

US MCM atrophy reflects 25 years of investment in counter-insurgency and precision strike at the expense of contested maritime warfare tools. The post-Cold War assumption was that no adversary would contest US naval access in littoral zones.

Iran has invalidated that assumption specifically by mining Kharg's approaches in the weeks before a US amphibious force arrived. The mines were laid deliberately, with knowledge of the buildup, exploiting the precise capability gap the US military's own journals had already documented.

What could happen next?
  • Risk

    An amphibious assault through a mined strait against anti-ship missiles and drones risks the first major US naval vessel loss since the 1991 Gulf War, with unpredictable escalatory consequences.

  • Consequence

    The MCM capability gap limits US military options to air strikes and blockade; a ground seizure of Kharg requires assets and expertise the force does not currently possess.

Different Perspectives
South Korean financial markets
South Korean financial markets
South Korea, which imports virtually all its crude oil, is absorbing the war's economic transmission most acutely among non-belligerents. The second KOSPI circuit breaker in four sessions — with Samsung down over 10% and SK Hynix down 12.3% — reflects an industrial economy unable to reprice energy costs that have risen 72% in ten days. The market response indicates Korean industry cannot sustain oil above $100 per barrel without margin compression across manufacturing, semiconductors, and shipping.
Migrant worker communities in the Gulf
Migrant worker communities in the Gulf
The first confirmed civilian deaths in Saudi Arabia — one Indian and one Bangladeshi killed, twelve Bangladeshis wounded — fell on communities with no voice in the military decisions that placed them in harm's way. Migrant workers live near military installations because that housing is affordable, not by choice. Bangladesh and India face the dilemma of needing to protect nationals who cannot easily leave a war zone while depending on Gulf remittances that fund a substantial share of their domestic economies.
Azerbaijan — President Ilham Aliyev
Azerbaijan — President Ilham Aliyev
Aliyev treats the Nakhchivan strikes as a direct act of war against Azerbaijani sovereignty, placing armed forces on full combat readiness and demanding an Iranian explanation. The response is calibrated to maximise international sympathy while stopping short of military retaliation — Baku cannot fight Iran alone and needs either Turkish or NATO backing to credibly deter further strikes.
Oil-importing nations (Japan, South Korea, India)
Oil-importing nations (Japan, South Korea, India)
The Hormuz closure is an existential threat. Japan, South Korea, and India receive the majority of their crude through the strait — they will bear the heaviest economic cost of a war they had no part in.
Global South governments (Indonesia, Brazil, South Africa)

Neutrality was possible when the targets were military. 148 dead schoolgirls made it impossible — no government can explain that away to its own citizens.
Turkey
Turkey
Has absorbed three Iranian ballistic missile interceptions since 4 March without invoking NATO Article 5 consultation. Each incident narrows Ankara's political room to continue absorbing without Alliance-level response.
