Arab does as arab will. The west has bean dealt a bloody nose time and time again.
Intervention has only served to cost lives and still the jehadies plot to overthrow western imposed pseudo democracy.
Imo western commercial interests combined with ill advised and planned regional border remarking exaserbated an already totally misunderstood knowledge of tribal and nomadic peoples.
I fear the west must butt out and leave the region to its own devises to avoid more innocent bloodshed than will unfortunately be spilled until the arabs sort out their own cultural mess.
