Trump Threatens to Destroy Iranian Bridge or Power Plant per Hormuz Ship Attack

Trump’s New Escalation Doctrine for Hormuz

US President Donald Trump declared on Truth Social that the American military would “bombard and destroy” a bridge or power plant in Iran every time Iranian forces fire on a vessel in the Strait of Hormuz. The threat marked a sharp escalation in the shadow war over the world’s most important oil chokepoint, with Trump explicitly warning that targets could include bridges and power plants “in or near” the capital, Tehran, regardless of whether the ships were attacked by missiles, drones or other weapons.

The announcement follows days of reported US strikes on Iranian infrastructure. The Wall Street Journal, citing a US official, reported that attacks on bridges were aimed at cutting supply routes to an Iranian naval base near the Strait of Hormuz. While the Pentagon has not officially confirmed those strikes, it stated that its forces had hit dozens of “military targets” with precision munitions, including air defense systems and coastal surveillance radars. In response, Iran renewed retaliatory strikes against targets in Kuwait, Bahrain and Qatar—all US allies in the Gulf.

Trump also repeated a threat to target the area around Iran’s “Pickaxe Mountain” nuclear facility, vowing to strike “with full force” in the near future. The US military has disclosed that 18 American soldiers have now been killed in the conflict. UN Secretary-General António Guterres expressed alarm over attacks on civilian infrastructure, calling them “unacceptable,” while Iran’s UN ambassador labeled the US strikes as war crimes.

Why the Bridge-for-Ship Threat Upends Gulf Security

The Logic — and Folly — of the Bridge-for-Ship Doctrine

Trump’s vow to destroy a bridge or power plant for every ship attack is designed as a deterrent by punishment. The idea is to raise the cost for Iran far beyond the damage it can inflict on shipping. However, the doctrine explicitly targets civilian infrastructure, something US forces had previously insisted they were avoiding. That both invites reprisals against American assets and creates a legal and reputational trap: deliberately hitting bridges and power stations can be seen as a violation of the laws of armed conflict. The threat may also play to a domestic base demanding toughness, but it risks entangling the US in a drawn-out tit-for-tat that is hard to calibrate and even harder to exit.

Iran’s Vulnerable Infrastructure and Escalation Risks

Iran’s bridges and power grid are concentrated, aging and intertwined with civilian life. Strikes on them would not only degrade military logistics but also cause blackouts, cut transport and impair emergency services. The reported targeting of bridges near the Strait of Hormuz suggests the US is already trying to isolate Iranian naval installations. Yet if Tehran retaliates by attacking regional allies—as it already has in Kuwait, Bahrain and Qatar—the conflict spills beyond bilateral US-Iran dynamics, threatening wider Gulf stability and energy infrastructure across the region.

Strait of Hormuz: The Oil Chokepoint Under Fire

The Strait of Hormuz carries roughly 20% of the world’s oil and a large share of liquefied natural gas. Even the threat of disruption is enough to jolt energy markets. The latest escalation comes at a time when global oil inventories are not overly flush, making supply scares more potent. While no major tanker has yet been sunk, the prospect of Iranian attacks on vessels—and a cycle of US retaliation that could damage ports or power systems on both sides—raises the risk of a prolonged navigation hazard, soaring war-risk insurance premiums and potential rerouting of tankers via longer, costlier paths. This scenario would ultimately land on consumers through higher fuel prices.

A Legal and Reputational Quagmire

By threatening civilian infrastructure, the US is on shaky ground under international humanitarian law, which requires distinction between military objectives and civilian objects. The UN Secretary-General’s statement and Iran’s war crimes accusation underscore the diplomatic cost. For Washington, a reputation as a power that bombs civilian electricity grids and bridges could strain alliances, complicate cooperation on sanctions and intelligence, and make it harder to rally international support for future operations. Even if the US frames its targets as serving a military function, the optics of power plants going dark in Tehran will be hard to defend in global forums.

What the Hormuz Crisis Means for Energy Markets and Shippers

• Oil traders and shippers: Expect a sharp rise in war-risk insurance premiums for vessels transiting the Strait of Hormuz and the Persian Gulf. Monitor whether Trump’s threat is followed by confirmed strikes on bridges or power plants; if so, some tanker operators may pause or reroute voyages, tightening physical supply.
• Energy importers (especially in Asia): Begin contingency planning for a partial disruption of Hormuz transit. Review strategic petroleum reserve levels and explore alternative suppliers from West Africa, the Americas or the North Sea, even at a cost premium. A sustained threat could make floating storage options more attractive.
• Shipping companies with Gulf exposure: Assess crew safety and hull risk. The reported Iranian attacks on vessels—now met with a US retaliatory doctrine that may escalate—mean any commercial ship in the area could become a target or collateral. Consider implementing additional onboard security measures and real-time threat monitoring.
• Consumers and fuel buyers: Should the Hormuz chokepoint become genuinely contested, gasoline and diesel prices at the pump are virtually certain to rise. The magnitude will depend on the duration and severity of disruptions, but the risk premium is already entering the market. Budgeting for higher transport costs is prudent.
