ELI5:How is ISIS recruiting so many people from so many different countries? What makes them more attractive than other organizations and why are people going out of their way to join?

If you read history, you run into this idea that the western, Christian nations have been battling Islam for ages. This is what people did with themselves when there was no hope for progress like what we have. They fought over geography and ideology and control. Religion is a powerful force that many people the world over have independently learned to teach their children. 

All of the above being said, there are a lot of people in the world. Disaffected youths *who happen to be Muslim* are taught indisputable history, taught about the crusades, and look at the more recent invasions of the Middle East as a call-to-arms, something to die for in their own little worlds where the alternative is to die for nothing. People seek meaning in something grand and are often sorely disappointed.

In short, you can't explain this bullshit to a 5 year old.
