Abu Hamzah al-Muhajir, who succeeded Abu Mus’ab al-Zarqawi as the Emir of Al Qa’ida in Iraq (AQI), broke over two months of silence on September 7, 2006. His call for an increase in violence over the next 15 days is a calculated risk intended to demonstrate his authority and, perhaps, root out informants in his organization. He has the tall task of rebuilding internal trust within the group and providing clear strategic direction for the organization’s future.
