I did not add the influence of recent terrorist groups in persuading often the very young to join their ranks. Two matters should first be considered: differences in intention and differences in motivation. They can further be broken down into a variable number of other states and intensions.
Nevertheless, several points can be noted:
1) A figure of authority claiming supernatural support
2) A figure of authority with charisma (sic)-Lenin, Osama, Gengis Khan, and multiple religious figures
3) An ethical and moral myopia that permits the use of violence
4) A sense of grivance in the recruited member
5) A particular view of the world-all the ills of the world for example are due to USA, Satan -often also USA or some other powerful state-
6) A poor or distorted historical viewpoint
7) A belief in the cleansing power of violence
8) Excessive need for attention by recruited member-many young recruits gained pleasure from hearing their names mentioned on TV. This constituted precarious fame.
9) Control of others
10) Excitement in a boring world
11) Particularly one full of rules and regulations
