Since you kind of elided it, their stated reason for killing is more or less &quot;because you&#x27;re not Muslim&quot;. We could take it at face value, but there&#x27;s nothing useful you can do with that information.<p>What would be useful is to know how so many people get to that place. What are the conditions that radicalized thousands to the point where they are willing to kill others just for being less Muslim than they see themselves?<p>I think the Post&#x27;s use of the word &#x27;blame&#x27; is meant to be provocative. Western powers obviously aren&#x27;t scheming to create ISIS with wealth inequality, and improved wealth distribution obviously won&#x27;t inspire ISIS to lay down their weapons. But if that inequality really is a cause, it&#x27;s worth trying to fix it if you want to head off the next manifestation of ISIS.
