The Iranians are the ones with a history of targeting civilians. Not the western powers.
The war could have been ordered by God. I am under the impression the Israelis would have waged war without our support. No one wants a neighboring country with the intent to destroy them and the ever increasing means to do so.
The ramifications for the future are however not all optimistic. I've no delusion that democracy is going to break out in Iran. Grass roots jihad will increase as the spirit of the antichrist starts to be pressured, and it will press back.
Yes, Iran will be crippled, then 5-10 years after Iran will be back as its usual evil self.
On the bright side, daily life in Israel without bomb threats will be a new experience.
