The IRGC operates over 1,500 fast attack boats from hidden coastal bases, forming a guerrilla navy that US warships struggle to counter in the narrow Strait of Hormuz. Half the fleet has been destroyed but the remainder continues attacking commercial shipping.
Iran reversed its decision to reopen the Strait of Hormuz within 24 hours, reimposing controls after the US refused to lift its port blockade. Two Indian tankers were attacked and Trump held an emergency meeting with advisors.
The US naval blockade of Iranian ports has not closed the Strait of Hormuz itself. Analysis shows why commercial shipping continues while Iranian maritime trade remains effectively strangled.
