If Jews "have to go back" and vacate the holy land, where exactly is back? Even in the wider eastern European region, where many of them originally came from, they were a people apart, separate, self governing and contrary to the native people around them, often trying to exploit and enslave them. Perhaps the meme of the wandering Jew is destiny, and some countries will always be forced to host a number of them. The key is to ban them from holding any authority or influence whatsoever over non-Jews (society, education, economy, and culture).
