Possibly worse I think, as Iran now know the US is a paper tiger that is not willing to invade, and that they can fight on almost indefinitely against air attack, while causing Billions of dollars of damage to US bases and allied countries which they don't like very much. Oh and they know what they only hoped before, that their power to block the Straight of Hormuz is a massive trump card. SO maybe they go back to where they were on nuclear weapons, but they feel emboldened in every other way, and will come out with fewer sanctions and more wealth
