By now, you've heard about the American citizen who is of Arab descent and who plotted with al-Qaeda. He is Abdul Omar Abu Ali and he has been charged with various conspiracy counts. He also intended to assassinate Pres. Bush.
Ali is a traitor, period.
What is more interesting, and horrendous, about this situation is that Ali was the valedictorian of "the private Islamic Saudi Academy in the Alexandria section of Fairfax County, a school for grades K-12." Why is that interesting? The Islamic Saudi Academy is a Wahhabist school financed by Saudi Arabia that teaches Saudi religious philosophy and has been called "Terrorist High."
