A key window into understanding ISIS is its English language "in-flight magazine" Dabiq. Last week the seventh issue of Dabiq was released, and a close reading of it helps explains ISIS' world view.
The mistake some make when viewing ISIS is to see it as a rational actor. Instead, as the magazine documents, its ideology is that of an apocalyptic cult that believes that we are living in the end times and that ISIS' actions are hastening the moment when this will happen.

The name of the Dabiq magazine itself helps us understand ISIS' worldview. The
Syrian town of Dabiq is where the Prophet Mohammed is supposed to have predicted that the armies of Islam and "Rome" would meet for the final battle that will precede the end of time and the triumph of true Islam.
In the recent issue of Dabiq it states: "As the world progresses towards al-Malhamah al-Kubrā, ('the Great Battle' to be held at Dabiq) the option to stand on the sidelines as a mere observer is being lost." In other words, in its logic, you are either on the side of ISIS or you are on the side of the Crusaders and infidels.
When American aid worker
Peter Kassig was murdered by ISIS in November, "Jihadi John" -- the masked British murderer who has appeared in so many ISIS videos -- said of Kassig: "We bury the first crusader in Dabiq, eagerly waiting for the rest of your armies to arrive."
In other words, ISIS wants a Western ground force to invade Syria, as that will confirm the prophecy about Dabiq.
We live in an increasingly secularized world, so it's sometimes difficult to take seriously the deeply held religious beliefs of others. For many of us the idea that the end of times will come with a battle between "Rome" and Islam at the obscure Syrian town of Dabiq is as absurd as the belief that the Mayans had that their human sacrifices could influence future events.
But for ISIS, the Dabiq prophecy is deadly serious. Members of ISIS believe that they are the vanguard fighting a religious war, which Allah has determined will be won by the forces of true Islam.
