On: US strikes Iran, Tehran hits Gulf states, says Strait of Hormuz closed

July 12, 2026.

The stated cause will be whatever incident preceded the missiles. A seized tanker, a violated inspection, a border provocation - the specific grievance will be argued for years. The structural cause is simpler and older than any of those details. A regional power with sufficient military capacity to damage shipping and neighboring oil infrastructure confronted a global power whose position requires that passage remain open. The strait is thirty-three miles wide. One-third of seaborne oil moves through it. The closure was announced. Whether the closure is physically enforced is a separate question from whether the announcement alters behavior. The announcement itself is the weapon.

Tehran struck facilities in the Gulf states. These states host American bases. They did not choose to be battlefields. They chose to host the bases because the alternative - refusing the larger power’s request - carried costs they calculated as greater. The missiles have now arrived. The calculation was always that this day would not come. It came.

The American strike was described as necessary and proportionate. The Iranian response was described as decisive and retaliatory. Each government’s rhetoric will be measured by what the territory looks like when the ordnance finishes. A speech about restoring deterrence will be delivered. The deterrence, after the speech, will be measured in cargo insurance rates and the price of crude. Those numbers do not listen to speeches.

I watched a war once where the commanding state believed its naval supremacy made its position permanent. The supremacy was real. The war lasted twenty-seven years. The supremacy survived. Much else did not.
