Well, you have to admit that being the civilized ones can be a real pain in the posterior, at times. Being able to cut loose on the barbarians has real appeal, but we're supposed to be "above all that". 
I am convinced we are in a struggle with Islam akin to the Punic Wars between Rome and Carthage.
It will begin in fits and starts, there will be several long intervals of "peace" but in the end one side must destroy the other.
People can blanche at the concept of genocide and ethnic cleansing all they want but the Islamists will not allow peace and they are gathering weapons that make hoping for peace foolish.
