But interviews with dozens of Iraqis living in Sadr City and other Shiite militia strongholds in Baghdad suggest otherwise. So do anecdotes from U.S. troops who have met with Sadr City residents and local leaders and who say there has been a shift in the things they hear.
"After March 25 was the first time I had anyone tell us, 'Go in and wipe them out,' " said Sgt. Erik Olson, who spends most of his time visiting residents of Sadr City's Jamila neighborhood gathering "atmospherics," the military's word for figuring out what locals are thinking.
It isn't surprising that people on the front lines of the standoff would lose patience with the warring sides. Their homes and streets have become battlegrounds, making it impossible at times to go to the market, the hospital or work. Military and militia snipers fire from rooftops. Militiamen launch mortar shells and rockets from residential streets. U.S. aircraft respond with devastating airstrikes that often cause casualties and damage beyond their targets.
It's a public relations problem that even some Mahdi Army members acknowledge, and a fragile truce reached by Sadr and the Iraqi government this month, which allowed Iraqi troops to deploy into Sadr City, suggested that at least privately, Sadr's political wing recognized the need to back down from the fighting.
Thousands of Iraqi security forces took up positions in Sadr City starting May 20 and faced no resistance from militiamen.
Ahmed, a 29-year-old Mahdi Army member who did not want his full name used for fear of being arrested or attacked, said the group was the only "honorable resistance" to the U.S. presence. He said people in poor neighborhoods depended on it for handouts of fuel, help with funeral costs, and food distribution. But he acknowledged that as fighting continued, support dwindled.
"Of course some people are expressing their resentment and anger against the Mahdi Army, thinking that without them, they would not be targeted and their lives would not be badly affected," he said.
Another Mahdi Army member expressed anger after Sadr in late April warned of "open war" against U.S. forces if operations targeting Sadr strongholds did not stop.
"Did he mention that the 'open war' . . . will be among the houses or residential areas?" said the man, a Mahdi Army street leader who feared having his name published. "Fight? . . . I will not join the fight."
