With Pearl Harbor, we had a much more tangible enemy that did not simply shrink back into the shadows.
Also, we had scores of leaders explaining that Islam is a religion of peace and focusing on Osama Bin Laden.
The big problem with that is people are not going to put up with really rooting out and destroying the problem. We have minimized the problem to a police action in a backwater nation that is already rubble.
Even now we are begging permission from the very people that put up the cash for September 11 to go after those responsible for putting up the cash. Hello? Is anyone home?
