Threatening to bomb Iranian power plants and bridges if Tehran disrupts shipping in the Strait of Hormuz makes for great television. It projects military superiority. It projects decisive action. It is also an operational fantasy that fails to grasp the mechanics of modern maritime asymmetric warfare.
The standard media consensus treats threats of retaliatory air strikes as a credible deterrent against Iranian naval aggression. Pundits debate whether an administration would actually pull the trigger, analyzing the domestic political risks of direct strikes on Iranian soil.

They are arguing over the wrong metric entirely.
Direct kinetic threats do not deter an actor whose whole strategic doctrine relies on low-cost, high-attrition maritime denial. Threatening to blow up a bridge in Khuzestan because a drone hit an oil tanker in the Persian Gulf is like threatening to smash someone’s mailbox because their dog keeps barking at your car. It ignores the cost asymmetry, the geographic reality of the Strait, and the operational mechanics of commercial shipping insurance. For another look on this event, refer to the recent coverage from NPR.
The Strait Is Not A Highway
Geopolitics coverage routinely treats the Strait of Hormuz like a standard international shipping lane—a highway where the biggest navy acts as the highway patrol.
It is not a highway. It is a narrow choke point, roughly 21 miles wide at its tightest, bordered by Iranian coastline, shallow waters, and hundreds of small islands.
When Washington threatens air strikes on Iranian command infrastructure, it assumes Tehran needs major naval assets to paralyze global oil flows. They do not.
Iran does not need to deploy frigates or destroyers to cripple transit through Hormuz. They do not even need to sink a single ship.
I have tracked maritime risk assessments for global logistics firms during heightened Middle Eastern tensions. The hard truth is simple: You do not need to destroy a cargo vessel to stop global trade; you only need to make it uninsurable.
The Math Of Lloyd's Of London
Consider how commercial shipping actually functions. An oil supertanker carrying two million barrels of crude does not sail because a U.S. Navy carrier strike group promises air support. It sails because a syndicate at Lloyd's of London or a Protection and Indemnity (P&I) Club writes an insurance policy covering the hull, machinery, and cargo.
The second tension escalates in the Gulf, underwriters designate the area a War Risk Zone. Premiums skyrocket.
- Baseline War Risk Rates: Typically hover around 0.02% to 0.05% of the vessel's insured value.
- Escalated War Risk Rates: Jump to 0.5% or higher within 48 hours of an attack.
On a tanker valued at $100 million, a jump to 0.5% means an additional $500,000 per transit just for insurance.
Now add cheap sea mines, anti-ship cruise missiles mounted on the back of civilian trucks, and swarms of fast-attack craft armed with rocket launchers. An sea mine costs a few thousand dollars to manufacture. Dropping three or four of them into the shipping channels does not require a military complex; it requires a wooden dhow under the cover of night.
If Iran drops a handful of unanchored mines into the water, ship captains stop sailing. P&I Clubs pull coverage. The flow of crude stops completely.
What does a U.S. air strike on a bridge in Iran do to lower war risk insurance premiums for a merchant vessel sailing past floating mines? Absolutely nothing.
The Air Strike Fallacy
Direct military escalation creates a feedback loop that plays directly into Iran’s strategic hand.
When political leaders threaten to strike Iranian bridges, power plants, or military headquarters in response to maritime attacks, they assume Iran fears physical destruction more than it values economic leverage. This fundamentally misunderstands the Iranian Revolutionary Guard Corps (IRGC) Navy.
The IRGC Navy was explicitly built from the ground up to absorb kinetic strikes while maintaining sea-denial capabilities.
- Decentralized Command: IRGC fast-boat squadrons operate out of hidden, fortified bases along a rugged coast.
- Mobile Launch Systems: Anti-ship missile batteries move constantly via civilian infrastructure.
- Asymmetric Cost: The U.S. spends $2 million firing a Standard Missile-2 to intercept a $20,000 Iranian drone or missile.
Imagine a scenario where the U.S. executes a retaliatory strike on an Iranian power grid following a fast-boat raid on a vessel near Fujairah. Washington claims victory.
Within two hours, Iran responds not by firing at U.S. warships, but by broadcasting an open warning to all commercial shipping that the Strait of Hormuz is now an active war zone. They fire off two low-cost anti-ship missiles into the open water near commercial traffic.
Global crude prices spike 15% before breakfast. Insurance underwriters cancel all coverage for transit through the Persian Gulf. Two hundred tankers anchor outside the Gulf of Oman, refusing to move.
Who actually won that exchange?
The U.S. blew up concrete and copper. Iran shut down 20% of the world's petroleum supply using $50,000 worth of hardware and a single radio broadcast.
The Misconception Of Deterrence
Mainstream political commentary operates under a flawed assumption: Deterrence is universal. The idea goes that if your threat is big enough, the opponent stops moving.
In conventional warfare between industrial nation-states, deterrence works because both parties have fixed infrastructure and centralized economies they want to protect. In asymmetric maritime warfare, deterrence breaks down because the targets are asymmetrical.
Iran’s economy is already heavily sanctioned and isolated from Western capital markets. Western economies, conversely, are hyper-sensitive to marginal changes in energy prices and supply chain disruptions.
Threatening Iran with infrastructure destruction ignores this vulnerability balance. Iran’s leaders know that long before a bombing campaign can force Tehran to capitulate, a sustained oil shock will trigger global inflation, political panic in Western capitals, and massive volatility in global equities.
The vulnerability is not in Tehran. It is in the energy markets of London, New York, Tokyo, and Beijing.
What Real Security Requires
If military grandstanding does not secure the Strait of Hormuz, what does?
Securing the Strait requires boring, unglamorous, operational-level logistics work that rarely makes headlines.
1. Convoy Escorts, Not Retaliatory Bombing
During the Tanker War of the 1980s (Operation Earnest Will), the U.S. did not secure shipping by threatening to destroy Iranian city infrastructure. They reflagged commercial vessels and physically escorted them through the waters with naval combatants riding shotgun. It is resource-intensive, slow, and unsexy. It is also the only thing that actually lowers insurance rates.
2. Mine Countermeasures (MCM) Prioritization
A fleet of stealth fighters is useless against a submerged mine field. Mine countermeasures—minesweepers, autonomous underwater vehicles (AUVs), and specialized clearance teams—are the primary military asset that keeps global trade moving. Yet, mine warfare remains consistently underfunded compared to high-profile carrier strike groups and strategic bombers.
3. Re-underwriting Risk Through Sovereign Guarantees
If private insurance markets freeze due to war risks, governments must step in to act as the insurer of last resort for critical energy shipping. By providing state-backed indemnity guarantees to merchant fleets, Western nations can neutralize Iran’s primary lever of economic coercion: the ability to drive up commercial insurance costs until trade stops on its own.
The Reality Of The Persian Gulf
Threatening to bomb Iranian power plants makes for effective domestic political theater. It projects strength to a public that views conflict through the lens of Hollywood movies and decisive air superiority.
In the real world of global logistics and naval operations, it is a empty threat.
Iran does not need to defeat the U.S. Navy in a surface battle. They do not need to keep their bridges intact to paralyze international commerce. They only need to convince a handful of insurance executives in London that sailing through the Strait of Hormuz is a bad business decision.
Until political leaders recognize that maritime security is an economic and defensive engineering problem—rather than a targeting exercise for cruise missiles—the global economy remains completely exposed to a cheap, effective, and un-deterred threat.
