I have no doubt that when Israelis have the state that they were promised, i.e. a tolerant, humane and truly democratic state of all its citizens, the wish to retain, reacquire - or even acquire by false pretenses - other nationalities will evaporate. Avineri is from the "if you're not for us you're against us" brigade. Most of Israel's citizens are neither. They are for a country they can be proud of. and hopefully they will eventually pull together to reappropriate it and achieve that.
