There's no question the rebels Americans are currently fighting for in Libya include in their ranks jihadis who in recent years traveled to Iraq and Afghanistan to kill Americans. The only question is whether that worries you or not.Take Abdel-Hakim al-Hasidi, a leader of U.S.-supported rebels in the fighting for Ajdabiya. His hometown, Darnah, has produced many jihadis, and after the Sept. 11 attacks, al-Hasidi traveled to Afghanistan to fight the "foreign invasion" -- that is, the U.S. military.
