I think Iran is playing a very smart game. They're not being irrational at all, in fact, it seems to me that they're angling to control the entire middle east.
But they're persians and everybody else over there is an arab so it's anyone's guess whether or not they'll succeed.
They're betting that they can exhaust us and drive us out of the area.
It's a game of intimidation.
As for Israel, the israelis are a lot more ruthless than we are and you can bet the iranian government knows it.
Again, it's true that some crazy might succeed in blowing up Tel Aviv, but the israelis would have missles and bombers in the air before the dust settled.

Once again, my main concern is the distraction.
We get told that:
The dirty liberals want to raise your taxes.
The dirty arabs want to take over the country.
The dirty bible thumpers want to take away your porn.
The dirty catholics want to take away your abortions.
The dirty blacks want to fuck your daughters.
