Ahmed Chalabi
Through the months of July and August, a series of skirmishes in and around Najaf culminated with the Imman Ali Mosque itself under siege, only to have a peace deal brokered by al-Sistani in late August. Al-Sadr then declared a national cease fire, and opened negotiations with the American and government forces. His militia was incorporated into the Iraqi security forces and al-Sadr is now a special envoy. This incident was the turning point in the failed American efforts to install Ahmed Chalabi as leader of the interim government. The CPA then put Iyad Allawi in power; ultimately he was only marginally more popular than Chalabi.
