The rich social systems defeating individualism.
It may sound very simple and less technical, but just so we know, the profile(s) of most suicide bombers has always been linked with a broken home and a failed social system. The culture of individualism in the West and Middle East has been documented to be one of the causative factors to innocent souls joining terrorist organisations. In the West, many are never taught the communal burden of loving your neighbor no matter the differences, but rather they are taught the nuances of establishing oneself by oneself!
Social systems in the United States cannot be compared to that of Africa where parents look over their children even when they hit the age of 40; where a depressed, unemployed man can still get back home to a shoulder to cry on. Ask any of the members of these terror organisations the background of their lives, and all we will get are traces of a non-functional home system, broken homes or even a society where no one supports the other.
