The facts are that the primary reason that Israel came into existence in 1948 is that the Arab Nation was not focused on subdivisions .e Palestinians, Jordanians, Iraqis etc. In fact few Arabs in Palestine saw themselves as Palestinians. Keep in mind the concept of nationalism was invented in Europe Jews became acquainted with it long before the Arabs. Had there been a strong Arab identity in Palestine as Palestinians the Zionist experiment would have failed.
Life is not fair. The Zionists were ready the Arabs were not. You can look at all the violations here and there but the facts are what they are. If you want to turn the clock back why stop at Palestine, what about Germany and Poland, what about the Tibetans and Chinese. What about America?
When it comes to Palestine where will you go back to, the UN Partition? (not accepted by any Arab nations and certainly not by the representatives of the Palestinian Arabs). Actually that would be a good solution because it would cause a separation between these two warring parties. The demarcation liens of the UN partition would create, literally, a Jewish state with a very small Arab minority and an Arab state with relatively small Jewish minority.
Or are you for the putative “democratic” BDS state of Palestine where these two peoples who currently can’t stand each other would be forced to live through a blood bath. Why not accept the full UN resolution 188 which calls for repatriation resettlement and compensation: “Resolves that the refugees wishing to return to their homes and live at peace with their neighbours should be permitted to do so at the earliest practicable date, and that compensation should be paid for the property of those choosing not to return and for loss of or damage to property which, under principles of international law or in equity, should be made good by the Governments or authorities responsible; Instructs the Conciliation Commission to facilitate the repatriation, resettlement and economic and social rehabilitation of the refugees and the payment of compensation, and to maintain close relations with the Director of the United Nations Relief for Palestine Refugees and, through him, with the appropriate organs and agencies of the United Nations;” not just a right to return.
