I couldn’t imagine Iran has the military capacity to close the Strait of Hormuz if the US Navy attempted to stop them from doing so, but given that a gutless community flippin’ organizer is occupying the Oval Office I definitely have my doubts that the US Navy would even try to stop them.
For all we know BHO made have negotiated a secret side agreement with them that the US Navy won’t interfere if they try to do so.
Some years ago Qadaffi closed the Suez Canal with a couple of mines dropped off a nondescript RoRo vessel
All it takes to close a strait is to make shipping traffic uninsurable
——a secret side agreement ——
that would be his death warrant
