Israel annexed the villages in south Gaza because the Arabs there heeded their leeders call in '47 to abandon their villages so the combined Arab armies could ethnically cleanse the Jews. The Arabs failed and the rest is history. Those who stayed became Arab-Israeli citizens. If you start or support a war and you lose, you lose your lands. Germany lost Pomerania, Silesia and East Prussia no one complains. Only the entitled Fakestinians.
