because Iran backed militias in Iraq are known as THE IRAQI ARMY - and are under the control of Badr and Hakim, who are closely aligned with Maliki, and they are not living in Sadr City.

And Sadr's militia, the Mahdi army, are not hiding behind civilians either.

THEY LIVE THERE.

And they are not going away.  

And we would get out of Iraq sooner is bullshit.  The US authorities, like bush and his cronies (including democrats) HAVE NO PLANS TO EVER LEAVE.

You are really uninformed. (also - no evidence that Sadr is currently in Iran, but even if he is, he does not have the ties to Iran that Hakim and Maliki do.)
