I don't see what the linked clips have to show about Palestinians or any other Arabs for that matter, since they're from an Iranian government-run TV station.
the iron horse said:
A good question: Why have other Arab countries denied the Palestinians from settling in their countries?
Actually Lebanon, Syria, and Saudi Arabia are all home to several hundred thousand Palestinian refugees and their children, and Egypt to about 70,000. And more than 2.5
million Palestinian refugees and their children live in Jordan. It's true that only Jordan has extended them permanent full citizenship, although in the other countries they can hold work permits etc., and most have long since been moved out of refugee camps and into regular housing.
By comparison to other refugee-deluged countries around the world, there is nothing particularly unusual about how the neighboring Arab countries have handled this situation. Most countries tend to balk at taking in, let alone permanently accommodating, large numbers of refugees from strife-ridden neighboring countries--because they fear "spillover" instability (which Jordan and Lebanon have seen lots of), because they fear economic drain, because they are loath to be seen as implicitly accepting responsibility for another state's internal problems, etc. etc.
One historical fact: There has never been a state called Palestine.
By this logic, most all present-day Arab countries--not to mention scores of other states elsewhere, whose borders were arbitrarily created by European bureaucrats and their local-elite cronies as the colonial era ground to a close--are illegitimate too. It's the rare nation-state that can claim to be based on any consistently endorsed "national" identity stretching back over centuries.
