No joke. GWB isn't going to label all of Islam as evil. To do so would be simpleminded. He will, however, use whaterver force he can muster to take down those indivduals and groups that initiate violence against innocents. He is not omnipotent or omniscient, will make mistake, and may lose.
THe general thrust of my comment was that GWB is not inclined to tar with a broad brush, gives individuals the benefit of the doubt, and plays hardball.
