Foreign fighters have become disillusioned with jihad in Iraq and have begun to exit the theater, US military officials reported yesterday. These fighters comprise al-Qaeda in Iraq’s best resource for suicide bombers, and their loss gives them much less operational capability. AQI leadership has not yet given up the fight, but prospects for replacements look grim: A growing number of foreign fighters are leaving or attempting to flee Iraq as U.S. and Iraqi forces have weakened al-Qaeda and forced its members from former strongholds, U.S. military officials say.
