America will wake up after the next terror attack-- for a while. After time, America will go back to sleep, until the next attack, when it will awaken again.
I think it would be along time before America went back to sleep.
Another attack, and you will see dead Arabs in the streets in America. I'm certainly not encouraging it, just predicting it.
You will see mosques burned to the ground.
We are slow to react because we are divided by politics and social structures. If those divisions melt away, we can be a pretty fierce opponent.
It will very much change the fabric of America.
