the fringe, while diluted, who have no purpose in life, who suffer from torn identities, come to us. >> all brothers and sisters come to jihad and feel the honor we are feeling. feel the happiness we're feeling. >> they want killing machines, that's why you see them, you know, doing these videos and watching kids watch these videos, and making kids commit crimes and kill because they are trying to establish a new generation of killers. >> it's the gang mentality. >> the gang idea is important because isis uses it to manipulate kids. a lot of the propaganda mixes the violence with scenes of camaraderie, friendship, the people in isis videos seem to be saying we did not belong where we were, but now we have found a home. a powerful message to the millions of unemployed, disconnected young muslims across the middle east.
