According to Wikipedia, "Cognitive dissonance is an uncomfortable feeling caused by holding two contradictory ideas simultaneously." Israel's concept that she has a right to be here is in direct dissonance with the concept of other groups that she does not have a right to be here. The resulting environment is threatening to Israel as a society. To this point there is nothing pathological about Israel. But when she chooses to fight her enemy, often using methods that are contradictory to her confessed faith as Jews, then cognitive dissonance becomes apparent. This does not say she is right. It does not say she is wrong. But her committment to destroy her enemy and her committment to the humanitarian dictates of her faith does constitute a cognitive dissonance, a problem also noted in predominantly Christian Europe following WWII. for example.
