Too bad part of the history of civilization has been destroyed but this is a slash and burn retreat along with looting by Daesh (the Arabic name for IS ISIS ISIL).

Why it took so long for the Iraqi Army to mobilize and why they would need the Iranians to advise them is really a harbinger of worse to come. I think perhaps these guys in Iraq are dangerous alliance, or amalgamation, of Baathist Militias and Islamic Fundamentalists. Enemies who have become friends of convenience. The ones in Syria are anti Syrian Baathist Militias and Islamic Fundamentalists -- truly a marriage of convenience.
Just a bunch of crazy ragheads that their respective governments have produced. So yeah, like rabid dogs -- they are to be eliminated.
