Allawi is going to be forced to do something about those scum in Fallujah.
If he can bring the rest of the Iraqis together (moderate Sunni, Kurds and Shiites) to demand something be done, then maybe the Iraqis (with some assistance from us) can finally drop the hammer on these animals.
It has to do with a violation of the ancient laws of hospitality. Our father Abraham extended hospitality to the stranger. He is not an enemy until proven otherwise. And what the people of Fallujah did was to turn a stranger into an enemy by spurning hospitality as well as honor towards someone from another tribe. Hospitality and honor are significant themes in the Middle East and they loom large not only in the Koran but in the Bible. The people of Fallujah may in the end be doomed if they do not adhere to these laws. And that will be their choice.
