The main point consistently missed here is that Israel is reacting, not instigating. When Israel reacts to a terrorist act or tries to prevent one it is viewed as a terrorist act by the Jew haters allowed to input here. It won't change. The best approach is to give 'em hell. Anything less is viewed as weakness and an excuse for more provocation.
