Don't forget that Israel has some of the very best intel world wide. They'll not be caught off guard, neither will we. Israel also has a huge stockpile of nukes....soooo I'd think that Iran's president may get one big ole' surprise.

I sure pray Israel's intel is up to snuff plus a wide margin.
Old RammaDammaDingDong knows perfectly well that the Israelis would retaliate, he expects and even desires that they do so.
What he might not expect is them shooting down his little firecracker before it goes bang. That would never serve to bring on the 12th/hidden Imam. But then again, he might think that it still would, at least if Israel still proceeded with nuking Iran.
