There has been a great deal of mainstream media attention lately, both video and print, regarding the fact that ISIS is recruiting based on the promise that their fighters are actually participating in the rapidly approaching end of the world.
At the same time, mainstream orthodox Muslim websites are already predicting Jesus' return as early as 2022, starting an Islamic prophetic clock set to run over the next 7 years, in the purportedly rapidly approaching run-up to Armageddon.
Dr. Michael Ryan of the Middle East Institute shared his valuable insights into ISIS' recruiting strategy. We learned that ISIS actually complains in their internal communiqués about their difficulty recruiting informed Muslims, because "Islam makes them tend towards life and their community". They find more success attracting Muslims they call "losers" -- ignorant about their Islamic faith and marginalized by drugs, alcoholism, crime, mental illness or recent life-changing events.
