Essentially the POD is that Israel conquerors both the West Bank and Gaza in 1949. The result would be that would be even more Arab refugees going into neighboring countries (700,000 refugees out of a total Arab population of 1.3 million refugees in OTL), likely exceeding 1 million. It could be possible that the Arabs left behind are going to be either Druze, Bedouin and maybe Christian. Although it could be possible that the Israeli government decides to expel the Arabs left behind, leaving a Israel which is almost entirely Jewish.
How does a bigger Israel with a large Jewish majority is going to effect it's relationship with the neighboring Arabs. Do the wars which occurred in OTL happen in this TL?
