The unrest and violence that has erupted in more than a dozen countries across North Africa, the Middle East and South Asia has refocused Americans' attention on two different but not disconnected historical movements in the Muslim world. The first is the campaign of terror launched by Osama bin Laden and an alliance of militant Islamic warriors who have sought to expel the West from Muslim lands, oust pro-Western dictators and unify those lands as a single Islamic nation for over 15 years. This movement, initially supported by America and its allies when it was used to dislodge the Soviet Union from Afghanistan in the 1980s, metastasized into the Al Qaeda terror groups that eventually attacked the United States on 9/11. The toll in American blood and treasure has been over 10,000 lives and trillions of dollars in damages and the cost of U.S. led wars.
