Fery, there is a big difference between the Jews of Europe and the Pals. The Jews never attacked the Germans, Austrians, Slavs. The Pals attacked Jews visciously and when Jews prevailed in a war brought to them, their attackers, some of whom no doubt left their homes in fear, did not come back. This was in the expectation that Israel would be liquidated. Many years later there is a desire to be compensated by the intended victims. And in the mix, of course, are the many Jewish victims that were excluded from Arab states, victims whose property was expropriated without compensation. The numbers of these Jews was far greater than the number of Palestinians who left Israel. Israel took these Jews in voluntaily and bore the expense of starting up their lives. This complicates you suggestion enormously, though there is room for something to be done by both Israel and the relevant Arab states but certainly not just by Israel.
