Again, these are not valid arguments against implementing the law on forming regions, which Maliki has previously refused to do with respect to bids from Basra and Wasit.
Additional confusion has been thrown into the mix because of unprecedented talk in some circles of Sunni regions joining the Kurdish areas. For their part, some Kurds have said they would like to see the implementation of article 140 of the constitution on the disputed territories before any region-formation, which again is an idea that enjoys no legal basis.
What seems certain is that Maliki is now coming under pressure on federalism issues from fellow Shiites, Kurds and Sunnis alike. That is an unprecedented situation which will add further pressure on his minority-government survival strategy unless he either manages to win over some substantial Sunni and secular allies or gives the Kurds some more of what they want.
