This is spiritual, it is evil, it is the devil.
Reading the OP article, it looks like Daesh/ISIS has found a power in being absolutely graceless.
Perhaps this will end up being so odious to “moderate Muslims” that they decide to unite against it.
I think some have committed to fight it: Abdullah & Sisi, for example, and some of the tribes in Iraq and Syria. The Kurds have had no choice but to defend their lands. But the above can’t do it alone with only limp-wristed U.S. help.
“Moderate” Muslim forces tend to be a mixed bag. The Iraqi Armed Forces are a particular disappointment. This force has approx. 271,500 active duty, 528,500 reserve, and training by the U.S., yet ISIL / ISIS is mostly kicking their you-know-whats.
