And Israel is the worst at promoting this false idea. There never was a Palestinian people. They were Jordanians.
Actually, the only Jordan is a river. The "Kingdom of Jordan" (formerly the "Kingdom of Transjordan," as opposed to "Cisjordan") is a wholly western created non-historical entity.
Arabs are Arabs. Period.
The war was against Jordan. Jordan lost the war. Jordan lost the west bank. Jordan lost Jerusalem, not some fictitious ‘Palestinians’.
And if it wasn't for the curse inflicted on the Jews by the name ‘mishpachat Dayan’, things would be much different and much better today. IMO
