See, I'm not sure that's entirely true. In fact, ISIS themselves disagree with you.
Late last year, an ISIS propaganda and recruitment publication named dabiq published an article titled 'Why we hate you, and why we fight you.' the author goes in to list, in order of importance, 6 major reasons for their religious war.
Number 1 is "Because you are disbelievers," number 6 is "Because you invade our lands."
The following statement is rather telling:
"What’s important to understand here is that although some might argue that your foreign policies are the extent of what drives our hatred, this particular reason for hating you is secondary, hence the reason we addressed it at the end of the above list.
"The fact is, even if you were to stop bombing us, imprisoning us, torturing us, vilifying us, and usurping our lands, we would continue to hate you because our primary reason for hating you will not cease to exist until you embrace Islam."
Now sure, this is ISIS propaganda, but it is being used for recruitment. In fact, the author herself is not a native Iraqi hellbent on revenge, she's a Finnish national who married into Islam, then fled to Iraq to join the caliphate. She even goes on to talk about the 'joy' of having her young son Martyed.
As far as the current attack is concerned, early reports are that it was about foreign intervention in the middle east.
But as far as ISIS is concerned... This war is VERY much about the doctrine of Islam, and their interpretation of it. (One could argue it's a very twisted interpretation of it, while one could also argue it's the most literal interpretation of it. I'm not smart enough to know myself.)
