There are, it seems to me, three powerful natural forces in play in the middle east, North Africa and "the Stans" The inevitable clash of Civilization, (the West vrs Islam), the Sunni/Wabi vrs Shiite war, and lastly the growing "nationalist" desire among Muslims for a super state "Nation of Islam". How nation states put together by British map makers of 100 years ago can survive the coming clash of historic nature forces is beyond me. At the end of the day there will be one or two Islamic super states and Iraq will be part of them.
Shiite Iran is bidding to be the leader of the Islamic super state, I am still waiting to see which state will bid to be the Sunni/Wabe alternative.
Hard to imagine western styled secular democracies taking root in such an environment. But even harder still to imagine would be the West/India allowing such an Islamic Super State to come into existance.
