Violence is very rarely spontaneous. Mostly it is a slowly brewed outcome of circumstance. If the causes are allowed to grow and fester untreated for long then the outcome is most certainly a cycle of violence that can sometimes reach unacceptable and unjustified proportions. So to say that a combination of Palestinian culture and Islamic faith creates an environment in which all children are taught to believe that salvation requires killing Jews is a vast generalization, to say the least. It would be more accurate to say that the Palestinian community lives under conditions of extreme political frustration and economic hardship, particularly in the Gaza Strip.
Religion is used to provide a foundation of belief.
The cause of violence, however, is political, not religious.
