Even if the clowns in charge think the take-away is 'we need even more bombs, and bigger ones', they're going to learn that when we're expending this much on a relatively minor power like Iran, the economics/resources for this scale of war against a major power simply don't exist. We're looking at Proud Prophet 2.0 [1] which was also a huge victory in defeat for the US. It's unfortunate that in the past we were able to learn from wargames, whereas now we had to see things play out in real life. Perhaps next time when we do a wargame against Iran and lose [2], we shouldn't just change the rules so we can win.
