A guy named Robert Evans at Cracked did just that. He read some 700 pages of the glossy magazine that ISIS puts out (Dabiq) and learned a lot but also learned how little we really know. Two conclusions he drew are 1) ISIS wants the West to invade, because it needs to have its final battle with the infidels on its home turf (not coincidentally at the town named Dabiq in Northern Syria) and 2) despite its murderous actions toward Americans and Europeans it reserves its real hatred for apostate Muslims, particularly those who practice the Shi’a branch of Islam.

It’s really worth a read, and at only two pages it’s not going to take up much time.
