Iran's nutcase theocratic regime finds itself in as lucky a postion as they could have hoped for.
They control their country militarily and can let many Iranian citizens suffer if this drags on.
But even better, if the Hormuz situation drags on and the world economy goes into the toilet, it's entirely possible that much of the world will blame America and its unwell idiot President for starting this. We have already insulted, threatened, mocked, trolled and punished our former friends as it is.
These Iranian psychos are probably thanking their lucky stars.
