[People who have left the ISIS] say that there comes a moment when the inconsistencies and apparent hypocrisies of their sheikh lets them down, and they begin rereading scripture and find ways that vouch for a nonliteralist reading of the Koran.

The systemic failure in the media in covering ISIS is that the majority of reporters are doing it in a semaphore fashion.

It's become extremely difficult to speak to active ISIS members now. I was speaking to them in 2015, and the last one was killed in a drone strike.

One of ISIS' biggest propaganda coups was the beheadings of the aid workers and journalists. Is [Emni], the group that is exporting fighters overseas, also the one that was holding James Foley and John Cantlie and Kayla Mueller?

It seems to me that a 9/11-style attack is impractical.

People who have left the group talk about how a religious inspiration took them to ISIS. It was their feeling of being marginalized as Muslims in the society where they were living, and then buying into the promise of a caliphate and of a Muslim land that is governed as in the time of the prophet. I have yet to meet anybody, or speak to anybody, who was not religiously motivated at some level.
