Imagine a meeting of the top ayatollahs in Tehran.
"Let's Bomb Israel!"
"Blow 'em to smithereens!"
"Blow 'em back to the Stone Age!"
And then a most wise one stood up.
"Uh, fellas, maybe we should stop and think a moment. We know Israel has the Bomb, probably lots of them, And we know they won't hesitate to use them on us if we strike first, and they are always in a high state of readiness: they will react within minutes. They will hit our largest cities . . . Tehran, Isfa, Ahvas, Qom. Millions of our people will be incinerated. Millions. MILLIONS. Is this what we want?"
The ayatollahs start to drift out of the room.
Moral: The ayatollahs may be evil, but they're not crazy.
