Aw, come on, you guys give up too easily.
Look at it in a different light.
How much does the govt of Iran hate Israel, and by extension, the U.S? If they had the capability to blow both countries off the face of the planet, do you think they would? Or do you think references to the US as the Great Satan is merely hyperbole?
With enough time and basically unlimited amounts of (oil) money, it is only a question of when this will happen. So we can wait for them to attack us, maybe nuke 7 or 8 primary urban targets, and say, gosh, we should have seen that coming years ago.
OR....you decide.
