It seems the only realistic solution to the problem on the Middle East is to redraw borders in that region. Let's face it the idea of multicultural state in that part of the world simply doesn't work. Kurds want their part, Shia want theirs and Sunnis theirs. The reason isis or deash is so successful amongst Sunni Muslims in that region is cause they are the only ones fighting for Sunni rights in that region. In any other scenario the majority simply rules over the minority without giving them any rights (that's why democracy simply doesn't work in that part of the world). If Sunnis had their own area where they could have some sort of Islamic state or republic then they would no longer need a group like isis to fight for their interests.
