Can Two Destroyers Reopen a Choke Point Iran Reclassified as Law?

Operation Epic Fury and What It Left Behind

The tanker war of the 1980s is the closest the Gulf has come to this — Iraqi and Iranian aircraft attacking neutral shipping, insurance rates spiking, Washington eventually re-flagging Kuwaiti tankers under the Stars and Stripes. That precedent is instructive and wrong in equal measure. The 1980s tanker war unfolded around a strait that remained open. This one began by attempting to close it.

On February 28, 2026, the United States and Israel launched approximately 900 airstrikes against Iranian military and state infrastructure in an operation named Epic Fury. Among the dead was Ali Khamenei, Supreme Leader for thirty-four years. A choke point carries its strategic weight precisely because of the volume it controls — the Strait of Hormuz had, before February, moved between 20 and 25 percent of the world's oil and liquefied natural gas through a channel navigable, at its narrowest, in under an hour. Remove the leadership of the state that flanks it on three sides, and you do not remove the choke point. You remove the only party that had calculated, for decades, that deterrence served better than detonation.

That calculation died with Khamenei. What replaced it was not chaos exactly — Tehran's institutions survived the strikes, and new men moved into the vacated offices — but the strategic logic shifted. A regime conducting deterrence has something to protect and a future to hedge against. A regime absorbing an existential blow has fewer reasons to be careful. The shift from deterrence to attrition is not a policy announcement. It is what happens to the math when the original math no longer applies.

Eighty Ships a Day, Then Two

Before February, roughly 80 commercial vessels transited the Strait of Hormuz every day. As of the first week of September 2026, Lloyd's List puts that figure at between 2 and 8. The arithmetic is not an abstraction — it is the operational definition of a closed strait.

Seventy-eight recorded maritime incidents since the February strikes produced that number. Not 78 crises, not 78 dramatic confrontations: 78 separate events of asymmetric attrition, each one calibrated to raise the insurance premium on the next voyage without necessarily sinking the hull. The Sidr changed that calculus. The Saudi supertanker was struck on August 31; two crew members died. A single named hull, a single dated attack, and the war-risk underwriters did what months of political communiqués had not — they repriced the risk to a level that makes discretionary transit arithmetically irrational for most operators.

The US Navy answer is the destroyer escort. USS Frank E. Peterson and USS Michael Murphy are the visible edge of that answer, shepherding the convoys that Washington counts as proof of flow. The problem is one of scale. Two destroyers, however capable, cannot replicate the throughput of a functioning commercial strait. Admiral Cooper's CENTCOM acknowledges roughly 9 million barrels a day moving under escort; President Trump's figure is 18 million. The gap between those numbers is either a shadow fleet of extraordinary size or a public-relations operation of ordinary ambition — and neither answer is reassuring. The escort model holds the line, but it does not reopen the strait, and a naval presence that cannot scale is not a solution. It is a holding position with a price tag attached to every barrel.

The Hormuz Exclusion Zone: Iran's Counter-Blockade Acquires Legal Clothing

A military fact, held long enough, acquires the furniture of law. Iran's Supreme National Security Council understands this. The September declaration of a restricted maritime zone, extending from the US Navy blockade line back into the Persian Gulf, does not change the physical reality of the strait — it reframes it. What was a military posture becomes, on paper, a jurisdictional claim, with all the procedural architecture that implies.

The commercial deterrent is straightforward: any vessel entering the zone is placed on Iran's sanctions list. The blacklisting mechanism is the point. Tehran does not need to sink every ship it wants to deter; it needs only to make the paperwork costly enough that charterers, insurers and flag states calculate the risk themselves and reach the correct conclusion without being asked twice. Seventy-eight maritime incidents since February have already done much of that calculation for them.

On September 5, Iran claimed it tested a new anti-ship missile directly above a US Navy warship transiting the zone. The US Central Command called the report a total lie. Both statements cannot be simultaneously true, and at least one of them is load-bearing for the other side's position — so neither will be withdrawn. What the exchange actually confirms, regardless of which version survives verification, is that the exclusion zone is not a bureaucratic instrument sitting in a drawer. It is being enforced, or performed, or both.

The legal clothing matters because it changes the question asked of every neutral shipper. Before, the question was military: will I be struck? Now it is also commercial and legal: will my vessel, my flag, my insurer survive the registry consequences? Iran has widened the cost surface. That is the operational logic behind the declaration.

Iran has widened the cost surface. That is the operational logic behind the declaration.

Eighteen Million Barrels, or Perhaps Eight Ships

Donald Trump, in late August, announced that 18 million barrels of oil per day were moving through the Strait of Hormuz. The Seoul Economic Daily's reporters, checking the same strait on the same dates, counted between two and eight vessel transits daily. These two figures cannot both be true, and the gap between them is not a rounding error — it is a policy argument dressed as a statistic.

Two readings of the discrepancy circulate among maritime analysts. The first: shadow fleet operations, tankers running dark with transponders off, moving volume in concentrated bursts that Lloyd's List cannot track in real time. The second: a small number of heavily escorted military convoys, each carrying enormous cargo, pushing through under US Navy protection at a cost per barrel that no commercial shipper could absorb. Rezaei's own phrasing — "the Americans are trying to smuggle five to six vessels through at great expense, but these ships are usually struck" — suggests the convoy reading, though the word "smuggle," applied to a naval superpower, deserves a pause.

Markets have rendered their own verdict, indifferent to which reading is correct. Brent crude has risen nearly 60 percent since January. That number does not lie, not because markets are wise but because they price what they believe, and what they believe is that the strait is not open in any meaningful sense. OPEC+ confirmed the same logic when it froze October production quotas unchanged — a signal, quiet and devastating, that the producers see no near-term resumption of normal flow. Somewhere a spreadsheet was quietly updated, and the revision was not optimistic.

The Collapse of the Mediators

The June 2026 memorandum of understanding, brokered in Islamabad with Pakistan and Qatar standing as guarantors, lasted roughly five weeks. Renewed hostilities in July finished it. The comparison to earlier Gulf mediation rounds is instructive, but only up to a point: previous interlocutors at least preserved the fiction of neutrality long enough for a ceasefire to stick. This time the guarantors dissolved before the ink had time to yellow.

What replaced the memorandum is more architecturally significant than its failure. Iran and Oman are now negotiating a corridor arrangement in which entry and exit points would be controlled by Tehran. That is not mediation. That is a neutral being converted into a checkpoint operator inside Iran's security framework. Oman's dilemma is the oldest in the region: a small state that has survived for decades by holding the door ajar for everyone is now being asked to hold it ajar for one party only.

The structural wall behind the diplomatic moulding was named plainly by US Energy Secretary Chris Wright. The blockade continues, he said, until Iran changes its position or its government changes. Two conditions, one answer: this does not end at a table in Islamabad or Muscat. Pakistan and Qatar performed the function a ceasefire process requires, which is to give the parties a face-saving interval, and the parties used the interval to reload.

What Oman does next is the indicator worth tracking. If Muscat signs the corridor memorandum, it will have crossed from neutral observer to co-administrator of a Tehran-controlled maritime lane — and every small state watching from the Gulf littoral will have read the geometry correctly.

Watch the Corridor Text

The Iran-Oman memorandum is the one document that matters now. Everything else — the competing barrel counts, the September exclusion zone, the missile test Tehran insists happened and Washington calls a total lie — is noise around a single negotiation. Iran and Oman are drafting a memorandum for a new shipping corridor, with entry and exit protocols controlled, in Tehran's current draft language, by Tehran alone.

That is the word to watch: controlled by whom, and under what verb. If the final text says the corridor's entry protocol shall be governed jointly, Oman retains a structural role and the corridor becomes a neutral instrument. If it says should, or omits the joint provision entirely, Tehran has simply acquired a second legal instrument to replace the one the exclusion zone already gives it — and every other regional neutral learns immediately what Oman's concession cost them.

Twenty mariners are already dead. The new realpolitik of the Strait of Hormuz is being written into that corridor text right now. Read the governance clause.
