There is nothing new about ISIS ideology. You cannot blame Arab or Islamic governments for this purantical form of Islam. It's been happening since the Sunni/Shia split after 632, and battle of Karbala. Every now and then, there is a revival of purantical Islam. Wahabi started his in the 18th CE, and there were several before him.
Also you cannot separate religion from politics in Islam. They are one and the same. The real spiritual Islam is practically dead overrun by medevial rituals,
When Muslims realize they live in a modern world, then there might be hope for the future of Islam. Right now, they are a confused lot.
