Intolerance downfall for Palestinians

Intolerance is the downfall for Palestinians, and I'm not even talking about current events. When the area was still the British Mandate of Palestine, it was the fear and intolerance of Palestine arabs which caused them to be hostile to the jews who were driven there by Hitler. History would have been very different if they found a way to live together instead of choosing to side with external arabs who wanted to push the jews to the sea.
