All questions of right to one side, I have never been able to banish the queasy inner suspicion that Israel just did not look, or feel, either permanent or sustainable. I felt this when sitting in the old Ottoman courtyards of Jerusalem, and I felt it even more when I saw the hideous 'Fort Condo' settlements that had been thrown up around the city in order to give the opposite impression. If the statelet was only based on a narrow strip of the Mediterranean littoral (god having apparently ordered Moses to lead the Jews to one of the very few parts of the region with absolutely no oil at all), that would be bad enough. But in addition, it involved roosting on top of an ever-growing population that did not welcome the newcomers.
There are only two worlds - your world, which is the real world, and other worlds, the fantasy. Worlds like this are worlds of the human imagination: their reality, or lack of reality, is not important. What is important is that they are there. these worlds provide an alternative.
