I think there is no public support for war in Iran, so the next President will have to do it covertly like Reagan, or massage the evidence like Dubya. I don't intend to disparage either men, as I think they were the 2 best Presidents of my lifetime. I think Reagan's method of arming both sides, keep them killing each other and weakened, was brilliant. And Dubya had both fronts( Iraq and Afghanistan) covered to invade Iran if there had been public sentiment. I think that was the plan, unfortunately America's will to fight is not there.
I think the next President will have to do something about Iran. I think the next President will be a Republican. I think GOP Presidents do what needs to be done, based on the information they are privy to.
Should Rand Paul win he will have an easier time making the case for war with Iran to the American people as a reluctant warrior, than say Sen Cruz, who has an interventionist foreign policy view much closer to my own.
