I think this crisis is just once again showing how unable different countries are from stepping outside their partisan positions. US and Iran wasted the perfect opportunity to cooperate at the start of the conflict at Iraq, while Turkey and Kurdish organisations are unable to cooperate at Northern Syria.

At the same time the Arab countries that are in the coalition fighting against ISIS are at the same time funding similar extremist organisations all over middle east.

Maybe it would be for the best to allow ISIS to conquer the whole Sunni area of middle east, while preventing them conquering the minority areas. Then the people supporting them would be able to live the dream that is Isis and their caliphate. We simply cant think on behalf of the Sunni Arabs. Let them experience their dream and take their own actions based on those experiences.
