The moment you carry out any of your dreams or your fantasies - travel around the world, climbing a high mountain, buying a new house, writing a novel, carrying out a sexual fantasy, traveling to an unknown country - the moment you carry out your dreams, it's always, by definition less perfect and rosy than it had been as a dream. This is the nature of dreams.
Amos OzIsrael is a fulfillment, and as a fulfillment, it is flawed. Dreams fulfilled are imperfect. And, Israel is imperfect, of course it is - a far cry from the monumental dreams of the founding fathers. One of the reasons is that their dreams were unrealistic. They were bigger than life. These were messianic dreams, dreams about total redemption for the Jews, for the world. Such dreams do not come true, not in their entirety.
