And a daisycutter display just outside of town.
Tempted as I was, until now, Mosul has been pretty successful from what I've heard. A display like that might be all that is needed for the town elders to take care of such rogue elements themselves(afterall, they freaked-out at least one Brit during Gulf WarI who thought we went nuclear ;-). A repeat performance would definately warrant moving ground zero inside of town.
