I'm siding with Zeke and Pete on this one.
As a peace gesture to the mullas we should deliver the deceased Shah as they have demanded. The Cromwellian solution usually quiets down the hubbub and the rabid warmongers go back to sharpening their long knives in the dark.
OP, taking out the power grid as you've envisioned violates quite a few conventions and treaties that we've fostered. Just because we've essentially used the Geneva Convention for toilet paper once or twice doesn't mean a logical precedent has been established, I hope.
