Al-Qaida's top leader may be dead, but terror experts warn against the man next in line for the position. Osama bin Laden's right hand man and mentor, Ayman al-Zawahri, is likely to be the new face of the terror network, The Associated Press reported. Time reported that the two met in the late 1980s and their friendship is believed to be the beginning of al-Qaida. It's not clear how a transfer of power will play out but terror experts tell the AP that al-Zawahri's followers may seek avenge for bin Laden's death with a surge of attacks on U.S. troops in Pakistan. But U.S. intelligence officials believe he lacks the charisma that held al-Qaida together, and the network may fall apart.
