You may be revolted by Harel'sfinal solution, but you still have to think about 5 million refugees, who have little point to their life except to hate Israel. They are indeed a long-term threat to Israel. So what can be done about them? They cannot be eliminated by force, only by agreement among the various Arab states which host them. And that will mean letting many of them settle in Palestine, the only place where they will be accepted, and building facilities for them so they can live decently there. But hang on - there are a lot of buildings in the settlements in Palestine which will soon be empty ... anyone see a solution there?
