“So what it’s true.”
Beyond what you’ve written, which is all true, the “Palestinian Arabs” are the Arabs that none of the other Arab countries want and further, they have become a “convenient foil” for the Arab World to screw with Israel. The Palestinians have allowed themselves to believe that they have been disenfranchised from “Palestine” and the rest of the Arabs have fed that notion to help to try and defeat Israel. The truth of the matter is that the Arab World regards the Palestinians as worthless crap that they don’t want to care for.
IIRC a long time ago the Saudi’s said the “Palestinians” were not welcome there.
And the Kuwati’s use them as servants in their homes.
No wonder they do whatever their told.
