Al-Abadi also met with Iranian defense minister, Brig. Gen. Husain Dehqan, in Baghdad; he stressed both Iran and Iraq are fighting (Sunni) terrorist extremism; and crucially, he said, "we do not support the war on Yemen," which puts Baghdad in direct conflict with Riyadh.
It gets even better; al-Abadi has gone to Moscow, where he hopes to get plenty of support -- and weapons. After all, ISIS/ISIL/Daesh is crammed with Chechens. Moscow wants the Caliphate smashed; as it thrives, there is a direct threat of a jihadi renewal in Chechnya.
So now the stage is set for the Battle of Ramadi -- remixed; Shi'ite militias plus Sunni tribals, the odd American adviser, and discreet help from Iran and Russia, against Caliphate goons, many of them mercenaries, lavishly supported by assorted wealthy Wahhabis in Saudi Arabia and across the Gulf. As far as the Empire of Chaos goes, Divide and Rule remains the sweetest game in town.
