You can go all the way back to the Bible, then forward all the way to the Balfour Declaration of 1917 and beyond — to the establishment of the modern State of Israel in 1948 — and I’ll be damned if anyone can make a solid case for the state of Israel or Palestine as concerns territory. What you can do is point out thousands and hundreds of thousands, if not millions, on both sides, who’ve had their lives shattered throughout the whole affair by the machinations of international politics, state conquest, and politicized ideology ("religionism").
Those poor people in Gaza, today. Those poor people of the past, Jews and Arabs both, who’ve had their homes, lives, livelihoods, and even families torn apart. And the fundamental reason why is because we senselessly identify individuals only on the basis of being party to some group, ideology, race, or [arbitrary] territorial boundary line.
I, of course, don’t know that it could ever be any different, given human nature and demonstrated behavior as either conqueror or conquered, but I still like to hold onto the ideal. As I’ve said before, America is a culture, a state of mind, an attitude. America exists all over the world, in the abstract, and that’s its chief power. Identifying America as a landmass is to have no real clue as to what America truly is.
The Jewish culture, because it was party to no specific state, no "official" territory before 1948, had no alternative but to develop a strong identity and culture capable of existing virtually anywhere. They did, and they prospered wherever they existed. I can’t help but wonder if that culture has not ultimately been weakened by tying it to a state that arguably had no compelling need or reason to exist apart from some irrational sentiment.
So, what we learn from all this is that no matter what the state says or promises, everything is always negotiable under the right circumstances, including your property, your livelihood, and even your life. Remember that.
