I wouldn't be too optimistic. You can see that various aides say different things. Some say US has a role to play. Others say Iraqis should unite to expel the occupiers.
Also nobody is saying Mahdi army should disarm and/or integrate into Iraqi security forces. Basically they remain second largest force in Iraq, outside of governmental control and no intentions of disbanding.
Granted, moderation from it's high members is a good thing but there is moderation and there is moderation.
