I would suggest that no-one should underestimate the ability of the evil regime in Iran to find other asymmetrical means to retaliate against their foes over forthcoming years. It took the Brits a long time to learn that kind of lesson from the defeats in the Boer Wars. The latter only lost because of overwhelming power of Britain, & the real dirty methods they used against civilians. Don't hold your breath for no retaliations of some sort spread across the globe when we least expect them.
