Fallujah: The question is: Have the bigwigs fled?
I suspect so, but there is one thing that leads me to think otherwise. The terrorists kidnapped Alawi's cousins and are threating to decapitate them unless the Fallujah attack is called off. That produces the suspicion that the bigwigs are still there, along with huge stores of ammo, etc.
We will know for sure in a few days, or weeks at most.
