You actually may have a point. There is a lot of malnutrition there. But I have another theory...
Quietly, in moments of reflection, many Muslims feel that if they fight ISIS they will be doing something against Islam, simply because ISIS practices a super fundamentalist form of Islam. So, instead of fighting they drop their weapons (for ISIS) and run.
I don’t think so, Navyguy. The Iraqi army is mostly made up of Shi’ites, and ISIS are Sunnis. In fact, when ISIS captures Shi’ites they usually behead them or douse them in gas in an iron cage and light ‘em up.
I guess they figure it’s much better to run then be captured.
