Fallujah could have been no problem...remember when they evacuated the city of civilians and cleaned out the gooners? There were actually 2 battles of Fallujah. If they were smart they would evacuate that shiithole and just let the air force level that place. Drop Daisy Cutters, MOABs, and clean out any old munitions out of he stock piles..
No way to evacuate it now. ISIS is holding the population hostage.
