Arabs have put Palestinian refugees in ghettos all over the Arab world, maintaining them as disposessed and miserable as if freezing them in 1948. Arabs can keep a grudge for 62 years easily, and for 10 or 20 times that long too. So the "right of return" is the fig leaf for the mistreatement, humilliation and keeping Palestinian Arabs in refugee camps as opposed to allowing the any option they want. They need to psychologically absolve themselves, thus uphold the "right of return". But from Yasser Abed Rabo to Saib Erakat, they know the "right" is Karameh, and not operational, as Israel won't and cannot absorb them. The Palestinian state may absorb those who want to return to Palestine. Som symbolic family reunification in Israel proper will do. This one, is the least contentious of the so-called "core issues", albeit the most emotionally loaded.
