That scenario is possible, but it still doesn’t solve the bigger problem: protecting the Strait from small, asymmetric attacks. Even if conventional military targets are destroyed, it’s extremely difficult to stop individuals or small groups who are willing to carry out suicide-style attacks using small boats, drones, or portable rocket launchers against ships passing through.
It only takes one successful strike to create a major disruption. If a single tanker or cargo vessel were sunk in the Strait, shipping traffic could halt almost immediately because insurers would refuse coverage for vessels transiting the area. In fact, maritime insurers often classify conflict zones as high-risk areas and can suspend coverage or dramatically raise premiums when the threat level increases. Without insurance, most commercial shipping companies simply will not transit those waters.
Trump declaring victory and leaving doesn't mean Iran will stop threatening vessels.
