I don't think Israel will attack for the reasons you expressed.
I'm not that optimistic. Why wouldn't Netanyahu think he's got the administration by the balls on this issue?
Or put it another way: Netanyahu is Chris Brown, America is Rihanna. Where logic is trumped by nonsense.
Also, there's no guarantee that the attack would succeed.
If you mean "succeed" as in actually destroying the program, I'm not sure how it can? The Iranian government may be run by sociopathic evil people (necessary component for dictatorships), but they're not stupid. Not all of their nuclear materials are stored at the locations, spots on the map that's passed around the Internet lately. Or even at targets on our confidental maps.
For all we know, they've quietly smuggled them into the basement of the local McDonalds. Or better yet: A hospital! A Mosque!
