"he did not take the offer of Israel citizenship" It ISN'T Israel. They're "territories occupied" "He lost residence remaining outside for extended time." According to Israeli Civilian Law, which does not apply in "territories occupied". " Same thing happens to US Canada non citizen residents too." We're talking about a CITIZEN of Palestine, IN Occupied Palestine, he's protected by the GC's. " A Palestinian born in Egypt does not get citizenship" He wasn't born in Egypt, he's a Palestinian from Palestine, in Palestine. " and if outside Egypt for certain time cannot return to live in Egypt" By your analogy, it's the US he shouldn't be allowed to return to.
