- Mojtaba Khamenei said Tehran may "open other fronts" if attacks continue, signaling prolonged regional disruptions to oil flows.
Iran Can Use Mines And Small Boats To Threaten Shipping
- Mines and small craft are likely Iran's primary tools to choke the Strait of Hormuz rather than large naval vessels.
- Rockford Weitz noted Iran has ~5,000 mines and can deploy them from small fishing boats, making clearance hard in a narrow strait.
Reinstate Mine Countermeasure Ships Fast
