Ok we control it too. We can turn off the flow at will. We have 3 aircraft carriers plus a bunch of bases. No ship passes through the straight unless we say so. We should charge actually. Maybe a toll of, say, $2,000,000 until we recoup our costs for stopping Iran.
The US could do that for a while, a few months maybe. They'd get bored and overextended. The logistics are terrible. There's no way that would even be financially positive, even if you ignored how much good will from other countries it would destroy (if there's any left).

The US will never recoup their losses from this unwinnable folly of a war. Nothing positive came out of it unless you wanted the current Iran regime strengthened.
