We discuss the 9-11 terrorist attacks, this year being the 10th anniversary. We provide a summary of the attacks. Why did these attacks occur? We attempt to provide some thoughts in answer to that tough question. We review Al-Qaeda and Osama bin Laden. We review the Sunni Islamist radicals. We also cover the Shias, as well as briefly discuss Iraq and Iran. We explore some of the feelings of that day. Participants: Dr. John Vance, Dr. Hans Vought, Dan Elmendorf
