War causes suffering. Look at the displacements after the Second World War - millions of Germans forcibly removed from hundreds of years of living in Silesia. Muslims driven from Hindu areas, and vice-versa, during partition of the Indian subcontinent. You don't hear the descendants of those people talking about being refugees 60 years and more later. They did what the Arab Jews who were forcibly removed from their homes did - made the best of a bad situation in another land. But the Palestinians were never given the chance - unwelcome in Lebanon, Syria, Jordan, or Egypt. Pawns used by these Arab governments, consigned to the dung-heap politically econonomically and culturally. Encouraged radicalism and fanaticism - Arafat was 'appointed' to head the PLO because the Arabs wanted a Fifth Column to help destroy Israel. Arabs already HAD the West Bank and Gaza. They weren't interested in rehabilitating the poor Palestinians. Only the destruction of Israel would do. So it seems.
