Would you like to see the typed notes from a meeting in London between Lord Rothschild, Lawrence of Arabia and leading Zionists? The meeting took place in 1919 thirty years before the state of Israel was formed and the word "Palestinian" is used several times.
The Arabs or rather the people who already lived in Palestine, had just evicted the Turks, it was their land, their territory and the British had agreed to help setup a democratic Palestinian government, but the British betrayed them and secretly agreed to grab some of the territory and assist in the creation of a Jewish colony.
The desire to setup a Jewish state on Arab land was an external political idea, there was no desire among Palestinian Jews for a "Jewish State" they wanted nothing to do with such an idea, it was foreign, a foreign and alien political ideology that was an insult to Judaism.
The vast majority of the inhabitants were not in favor of carving out some arbitrary area (already occupied) and allowing that to be ruled by a Jew supremacist government, it was an unpopular, fringe idea but the British went along with the stupidity just as the USA is going along with today's stupidity.
It was already theirs ! They had lived under Ottoman rule for 400 years and had just forced the Ottomans out !
