al-Sadr has suggested his party and the Communists they're coalitioning with should with hold forming a new government until the demands of the protesters are met: rudaw.net/english/middleeast/iraq/190720181
To be honest I really wouldn't have guessed that "Muqtada al-Sadr will join the government and enter into a coalition with Iraqi communists" would have been one of the likely outcomes of the war in iraq.
A coalition of communists and Iran-aligned Shiite Islamists are about to take power in Iraq, and somehow people still believe that the whole “bumbling Empire” thing is bullshit. It’s pretty obvious that US foreign policy in the past few years has been wildly incompetent and self-destructive, yet somehow people still think they are playing 4D chess in Syria and elsewhere.
