RE: There Is No Such Thing As Palestine/Palestinian People - From The Mouths Of Arabs
I think you may have got the wrong end of the stick on this question. The end of WWI brought about the division of the former Ottoman Empire by the western powers, the British part of the Levant bordering their possession of Egypt was named Palestine.
Israel displaced many non-Jews from the Palestine's north coast and declared itself a state. Then in a series of wars Israel took control over parts of Lebanon and Syria as well as the eastern and southern portions of Palestine.
There were Jews long established in the area, as well as more recent immigrants. The Palestinian people are the non-Jewish original inhabitants prior to the establishment of the Israeli-state . They very much exist.
The quote from Hafez Al-Assad is a reference to pan-arab nationalism and that Palestine was an imperialist creation of recent invention which is not denied by anyone.
Palestine is in the Bible, it is the land of the Philistines, the whole coastal part was called by the Roman's from thee 1st to the 7th Century Palaelstina (Prima, Secunda and Tertia), and covers the area of present Israel.
