I happen to believe that the standards of war are different, so that the refugee problem, while unfortunate, was ultimately not caused by the Jewish side. Israel's position is better than others today, because the refugee problem was created in 1948, before the formulation and adoption of the 4th Geneva Convention. Otherwise, there might have been a hunt for "war criminals", etc. And there were some crimes committed, although the majority of Arabs just fled. Let us be happy with this. When Israel was admitted to the UN, it promised (as a condition of admittance) to take care of the refugee problem. How this will be done in practice? To my mind, refugees who left property behind are entitled to compensation. Israel stated in the past that the Arab states who participated in the 1948 war are also responsible for the refugee problem. I assume this will come up in the question of how compensation money will be paid. Likewise, Arab states who took the property of Jewish refugees will be asked to contribute. The whole world will contribute.
