Assuming people would want to leave, where would you "resettle" them to? Nobody in the region seems to want to take them. Egypt is right next door and is totally intractable on the subject. Other nations are not rushing forward with proposals either: Jordan and Lebanon are still reeling from the Syrian disaster and have enough problems without adding a new wave of refugees, plus their history with Palestinians camps is not good... You can count on Saudi Arabia and the Gulf states to not lift a finger to take in Gazan refugees. What's left? Syria, Yemen?
