Will The U.S. Better Understand Another 9/11-Type Attack ?

The U.S. is providing real-time, intelligence assistance to Turkey in it's air strikes against Kurdish separatists in Iraq according to the news services today. Also in the news is more killing by our "ally" Israel of Gaza "militants". This is all taking place in the context of our slaughter of Iraq, sabre rattling against Iran and our instigating and support with weapons of various African war enterprises.

If , and I hope not, when or if another 9/11-type attack happens in the U.S. will we Americans better understand why it happened?
