I suppose one could take this understanding and apply it to the Indian tribes of the Americas. Doing so does not take away their rights to having been free peoples of these lands. Other people did that.
Well...
Many Jews over the years tried to buy land in Israel...(before WWII)
But kept getting told that their land deeds were worthless. (Simply because they were Jewish)
For centuries this had been going on and the last remnants of the Ottoman Empire refused to recognize any Jew's claim to own any land at any time. Simply because they were Moslem and Jews were Jews. In fact only nomads did live in the area...
The land was practically useless to everyone...it was "travel through" land that nobody had a reason to stop in unless they were forced to because of mechanical problems.
(It was in that bad of shape and desolate)
Until 1948 and the stroke of a pen. (So to speak)
Then there was a game afoot.
And when the British finally got tired of hearing the complaints and left. (Not that the complaints were unjustified or unwarranted) the whole Arab world came in to attack them and wipe them out. And so America gave Israel a bunch of WWII surplus equipment....which they used extremely effectively.
And we should have let them have a free hand...there would be so many fewer issues today if we had. But we called them to go back home and stop invading those who invaded you. (They were kicking some serious donkey)
There were many groups at that time that were interested in guerilla warfare that would destabilize a nation and allow a new slate of leadership... because most of the nations in that area were extremely weak at that time.
There was one such micro group that started in Tunisia but got tossed out and went to Egypt where they found fertile ground and grew in numbers.
The Egyptians were slow to respond but they did finally and began to slaughter them wholesale. This dissident group ran all the way to Syria. (There wasn't anything in Israel yet) This dissident group engaged in the same thing there and finally got the same results as what happened in Egypt.
So this group went off to Jordan. And started up once again.
And the Jordanian King was still pissed off over losing land to Israel when they thought that their invasion with the other 5 countries should have been a cake walk. Now with this dissident group destabilizing his rule he got an idea of how to kill two birds with one rock. "That land that Israel took from us...you dissidents can have it and occupy it. And you had better or else I'm going to do to you as Egypt and Syria did starting next month"
And that's where the Palestinians actually came from.
Now the nomads and actual few residents of the area Israel now occupies...they didn't mind whatsoever. Israel turned that sand pile into a literal garden... complete with medical facilities, libraries, running water and sewer.... restaurants and shopping malls. Paved roads and all kinds of infrastructure like electricity. They loved every minute of it.
