The reasons why Israel and Palestine have an unending conflict is because of the intervention of the European and the west, they intervene because they have to divide and take advantage with their resources, "Chaos Theory" is a common tool to do that. The middle east as a whole is quite divisive because that's what the west wants to. That's the easiest way to wage a profitable war. Look what happen to Syria, it's another chaos theory at the same time to keep the pressure towards Russia logically.
