The assumption you’re making is that there was some continuous presence there that somehow became Israel. Unless you accept the bible as authority, there is absolutely no such presence.
I would agree that there was no continuous Jewish government entity that became Israel. Likewise, there was no continuous Palestinian government entity that could become Palestine.
There has been, however a continuous Jewish and non-Jewish presence in Israel for thousands of years.
So you accept the Palestinians right to keep their home, you just don’t accept their tactics?
Which specific Palestinians are we talking about? And which "home" are they keeping?
Do I like the regular use of terror attacks - funded and encouraged by people with no interest in the wellbeing of the Palestinian people - to further the Palestinian cause? No.
If your neighbours used terrorism to resist a Mexican takeover, I suppose you’d be out there condemning them and offering up your home out of shame?
No more than you have given up your house out of shame for how its land was taken from previous owners.
Jews who were forced out of the US allied gulf states definitely should have the right to return to their homelands.
Do they?
They are not and never have been a significant fraction of the Israeli population, which is almost entirely European immigrants within a single generation (including Russia).
No. Yes, Europeans made up the majority of immigrants, but hundreds of thousands of early immigrants were Jews that had been expelled by Muslim nations. The Russian immigrants largely came post-USSR.
You’ve made a conclusion about Israeli land claims which is directly contradictory to your own views about your rights.
What, praytell, are my conclusions about Israeli land claims and my own views about rights?
