The “palestinians” are largely immigrants from Syria, Jordan, and Eqypt.
What-is-now Israel was largely empty for a good 1000 years until the mid-1800s when Jews returned from the surrouding area (purchasing lands from the Turks) and Jewish people from Russia fled the various pogroms.
The exception to this was Jerusalem, which was a mixed town of about 50% Jews, 30-40% Christian arabs, and the rest Druse or arab muslims.
The al-asqa mosque on the Temple mount was pretty much a deserted ruin -— the legend that it was a “holy place” where Mohammed landed being a fairly recent myth for pure Western consumption -— it was BUILT AFTER HE WAS DEAD.
Anyway, “East Jerusalem” became “Arab East Jerusalem” in the early 1900s when German-equiped Jodanian troops commited ethnic-cleansing and kicked the Jewish people out of their homes where they (their families) had been living for 2000+ years.
Regarding the rest of the arab populations, they were basically lower-class arabs who came to Golan and other Jewish areas to get work -— the Jewish returnees in the 1800s were building and needed labor.
100 years later, those arabs claim to be the natives, despite all truth and easy disproving of their claims.
(Same things is happening in Europe, BTW, so your kids will have fun with that.)
I’ve read Tom Friedman, and he doesn’t dismiss the number of Arabs that had been living in the area for centuries. Even in the Old Testament, there are other people already living there.
As far as Europe’s situation, in 100 years they WILL be natives there (and Europe will have to deal with that).
