The 9/11 Commission Report: The Hamburg Contingent

By early 1999, al Qaeda was already a potent adversary of the United States. Bin Ladin and his chief of operations, Abu Hafs al Masri, also known as Mohammed Atef, occupied undisputed leadership positions atop al Qaeda’s organizational structure. Within this structure, al Qaeda’s worldwide terrorist operations relied heavily on the ideas and work of enterprising and strongwilled field commanders who enjoyed considerable autonomy.To understand how the organization actually worked and to introduce the origins of the 9/11 plot, we briefly examine three of these subordinate commanders: Khalid Sheikh Mohammed (KSM), Riduan Isamuddin (better known as Hambali), and Abd al Rahim al Nashiri. We will devote the most attention to Khalid Sheikh Mohammed, the chief manager of the “planes operation.”
