Thank you, Jonathan in Tel Aviv, for your interest. Your analogy is interesting, but doesn't hold up in one respect; the Palestinians have always lived in what is Israel since 1948; whereas the Alexandrian Jewish community, overwhelmingly, were recent immigrants, rarely going back more than three generations in Egypt, and foreign nationals as well. The Karaites were the exception.
Nasser was much harder on his Egyptian opposition than he ever was with the immigrant communities, who were protected by foreign passports. Sadat opened up to the West and things were somewhat easier. Today, under Mubarak, there is hope of some compensation, even if nominal, for the victims of the sequestration decrees. Whether foreign nationals will be able to claim compensation is still undecided. I for one would be delighted to see Alexandria and Cairo the cosmopolitan cities they once were, with thriving Greek and Jewish communities.
