Has Sadr returned stronger?

"Given the combination of SIIC leader Abdul Aziz al-Hakim’s [wiki] absence from the Shia political scene, the training Sadr received in Iran, and the timing Tehran chose for his return, Moqtada al-Sadr has obviously returned strong. Strong enough to summon seven Iraqi governors to meet him and listen to his instructions about how they should run their respective provinces in central and southern Iraq at the same time his militiamen were fighting the police forces of at least one of those provinces."
