The issue of Palestinian refugees is not so much Israel being the occupier, as one might believe. Palestinian refugees are actually a group of people cynically used by Arab leaders for their own benefit. They are not granted citizenship by the PA or any of the Arab countries within which thy reside, such as Lebanon and Syria. (The notable exception to this, to their credit, is Jordan.) They are not allowed to work, marry, leave the refugee camp... Compare this to the Jewish refugees from Arab countries (and from Europe after the Holocaust) who were unceremoniously thrown out of their own countries, (in contrast to the Palestinian refugees who mostly left,) and were immediately granted full Israeli citizenship.
