To truly understand this question, you must understand the Palestinians. The "Palestinians" are mostly non-Hashemite Jordanians and Non-Saudi Arabs from the Arabian peninsula. The fabricated "history" of the Palestinians is hard to reconcile with true history. Read anything babout the history of the region, even Mark Twain's "The Innocents Abroad", but I am suggesting you read up about the history of the Palestinians (and the region in general) under the Ottoman Turks (pre-1917) and under the British. You'll be surprised that there were no such "Palestinians", and that the national identity is a much more recent thing. That is not to say that they are not a distinct group of people with unique social problems and general issues. But don't make the mistake that the "Palestinians were living there first". What does that mean?
