Any idea why not? I always thought countries with that much incest have real biological problems. It cannot be healthy for a baby boy in the womb to be carried by a vitamin D deficient mother covered in a Burka. In fact, I cannot picture much positive there.
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.
