Israel is entitled to all the West Bank, Sinai, Gaza and south Leb for the same reasons that allowed the French to incorporate, once and for all, Alsace-Lorraine. Aggressors who lose do not keep the spoils and in fact lose their front in most cases. Arab states and their shock troops "Palestinians" have been aggressors even before the state was declared and the aggression - the Jihad - continued constantly with diplomatic and economic boycotts, terror and outright open warfare to this day. No, Israel is entitled to much much more than little settlements.
