A matter of perspective
There are not too many Palestinians of the last generation who don't remember the streets of Amman running red with Palestinian blood during the late King Hussein's Black December strike on the PLO in 1970. And Syria invaded Lebanon in 1976 for the express purpose of 'containing' the Palestinians which they did with ruthless efficiency: the number of men, women, and children murdered by the Syrians in the Palestinian camps in Tripoli in 1984-85 is yet to be known. And while we are on the subject, let us not forget that both Kuwait and Libya, brotherly Arab countries, threw out into the desert their entire population of Palestinians in the very recent past.
