While I share the author's concern over the way the Arab/Moslem nutjobs are pushing the world of late, I cannot disagree more that the civilized world should reject "any clash of civilizations of the kind desired...". Why? Because if one side declares war and starts fighting, and the other says "I don't want to fight and won't do it" then the passive side loses, big time (especially with nukes in the equation.
Sometimes war is forced on a country or group of countries, and if they wish to survive then they must not only fight back, but must fight better so as to emerge victorious. The Arabs/Moslems seem intent on a clash of civilizations the likes of which haven't been seen since WW2. We had better react, and do so powerfully and quickly, or we will perish.
Yes it is a "clash of civilizations".
But to defeat a civilization is not something the military isn't proficient at.
It will take more then bombs and troops. You're trying to defeat an idea. Not easy. And our cherished free and reckless speech is not moving us forward.
