Howdy Superfly; The reason that the Arab countries, most governments, and NGOs do not make reference to or acknowledge the Jewish refugees from the period between 1948 and 1967 is because they and their descendants have been absorbed into various countries (primarily Israel but also many Western countries) and now hold full citizenship in those countries and have managed to rebuild their lives. In contrast, with the sole exception of Jordan, the Palestinian refugees and their descendants have been denied citizenship in any Arab country (including the PA) and have been kept in refugee camps on the UN dole for the past 59 years (including Jordan). It would be very embarrassing for the Arabs to admit their shabby treatment of their own refugees compared to the way the Jews treated theirs. Also, it would entail equal compensation for Jewish and Palestinian property loses which the Arabs are loathe to do. Thank you for your very carefully phrased question.
