Clearly, you have absolutely no idea what is behind all this. The Arabs were offered a state and proceeded to chuck it away and to launch an all-out war (a jihad) against Israel, which had done nothing to hurt them. There is a problem because Islamic law does not permit anyone but Muslims to occupy what has been Islamic territory. Thus, no-one complained when the Egyptians occupied Gaza or Jordan the West Bank. But Israelis are Jews, so everything has to be done to expel or kill them. That isn't goiung to happen, but the Palestinians still haven't worked that out.
