I regret to inform you that your calculations are woefully wrong.
First, why invade Iran? As noted above the moment ships start getting sunk, shipping ceases. A blockade of Iran would be militarily easy to do with little risk. No boots on the ground and cheap than an all out invasion. Eventually they will figure how to smuggle some oil but the Ayatollahs would likely be overthrown. If you think republicans are drooling religious nutcases, you need to read up on the beliefs of many of Iran's leaders. We don't need a war but we do want to live in a world in which people like those that lead Iran do not have nukes.
Even if the US did invade (and we never will) any military historian would tell you that western military casualties in terms of percentages killed are much less than in even recent wars like Vietnam. If US could conquer Iraq in 2003 at the cost of less than 200 lives, casualties in an Iran war of invasion, holding the place only long enough to take apart the nuclear sites, ought to be relatively low. But the blockade is cheaper and easier, Iran has no cash and a loss of oil revenue would be crushing to them.
