Pat Lang posted an interesting response to a friend On identity and the state in the Middle East today:these countries are not really post Treaty of Westphalia nation-states. They were created by the colonial powers in the image of European countries that more resemble that model. In fact, these Middle East countries are inhabited by disparate groups of people who self-indentify within their group or perhaps withing several groups they belong to. These peoples do not identify with the state in which they live unless they happen to be run it. Thus, the Kurds feel no actual loyalty to the thing the British called “Iraq.” They are quite willing to cooperate with other Sunni people, in this case Sunni Arab tribes who are also indifferent or hostile to the government in Baghdad now that it is run by their ancestral enemies, the Shia Arabs. The Kurds would not lift a finger to help “Iraq” if they were left alone in their mountains. What they yearn for first last and always is Kurdish independence. The same situation exists in Jordan a country that is in essence a “reservation” for Sunni Arabs. It has been that since it was created by the Brits in payment of a World War One obligation to the Hashemits Emir Abdullah. This obligation originated in Abdullah’s support for the British during the war. When Iraq was under Sunni rule Jordan supported Iraq. Shia run “Iraq” means nothing to Jordan. The same this is true around the region.
IS is different from all these states. It does not recognize the legitimacy of the notion of countries at all and seeks a world wide theocratic state beginning in the Middle East.
The mozaic of all these groups that exists on the ground in the Middle East does not fit the boundaries of the
Sykes-Picot world created after WW1. Come to grips with that.
