We can look into the larger picture of the Middle East and then into Iraq and look at what's happening in Lebanon. Lebanon is divided. Syria has disintegrated. Yemen has disintegrated also. Shiites supported by Iran took over the capital city of Sana'a. We see the pressures inside Bahrain and inside Saudi Arabia between Sunnis and Shiites. In Iraq things have also disintegrated. Sunnis in the northern part of Iraq are being controlled mainly by the Islamic State. You have Kurdish autonomy. There is an almost independent entity inside Iraq and they have a Shiite...and the pressure on Baghdad, the mixed capital city of Iraq, is enormous. There have been hundreds of terrorist attacks during the last few years. I cannot see a magic wand that can reunite all Iraqis under the same nationality as they were in the past. The pressures between the two forces of Sunnis and Shiites in the Arab world are so intense that they are causing more disintegration in the area. And unfortunately as I see it, they may cause more and more tensions and frictions between these two sects.
