" When we examine , not the language of propaganda, but the witness of the combatants themselves, religion does not occupy the first place. Their motivations are more often secular, they mention their sympathy for a population reduced to poverty, the victims of the whim of ruling classes that live in luxury and corruption- rulers able to maintain themselves in power thanks only to the support of the American government ( as in Pakistan, Saudi Arabia and Egypt). They speak of the members of their families or their local communities who have suffered or died by the fault of these governments ( and thus of their protectors); and they want to avenge them. The thirst for vengeance did not wait for Islam to appear in the world, and the appeal to the law of an eye for an eye and a tooth for a tooth is universal. "
