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.
He's a complete nut...oh my the 12th Imam...#1 there's no such being #2 he's completely delusional #3 the Israelis' know just what they're doing [they've proven that many times] ...and it's the same old fight...good vs evil...
