The comparisons are legion to illustrate what’s wrong with your argument here. Mexicans have a high degree of American indigenous DNA. If in the future they take up better arms and come to your house, are you morally obliged to let them take it away and put you on a boat back to Europe? Because of some vague historical connection to the land? They even have Aztec legends that connect them to North America. Does that mean you have no rights today?
I don’t think I made the argument you think you are addressing. I don’t feel strongly about Jewish history in Israel defining modern Jewish ownership.
You chose an arbitrary start time intended to make the Israelis out to be the aggressors and tried to claim that because the land was taken by force it should be returned. If your standard is that all land taken by force should be returned to its original owners then I’m not sure why you are solely concerned with Israel or who you would consider the original owner.
However, to address your hypothetical, if some group with legends connecting them to my home conquered the US and took it away from me by force, then no, I would have no practical rights except what they gave me. That would suck. In such a scenario I would hope that I would be able to rebuild in some other place and not just teach my children to detonate a suicide vest in a crowded market, but I guess different brave and beautiful cultures have different priorities.
The crux of what is wrong with this is that you’re asking the Palestinians to give up their land today to immigrants from Europe because those immigrants claim that land based on their ancient holy book. It’s not like the Israelis were there and just asserted a new politics - they are literally all immigrants from Europe, mostly without even a trace of parentage documented in the Middle East.
That is simply wrong and I’m fairly certain you are aware of it. In addition to the Jews who fled Europe, a significant fraction were ethnically cleansed from essentially all other Middle Eastern countries or fled persecution from same.
I assume you will likewise champion the Jews who were kicked out of Iraq, Yemen, Syria, Egypt, Libya, etc. returning to blow up busses in those countries that mistreated them?
Why don’t you apply this same rule to Palestinian land rights? Why is it ridiculous for you and me to keep our land in the face of ancient indigenous claims but not ridiculous for them to do the same?
It is not ridiculous for us to keep our land, any more than it is ridiculous for Israelis to keep their land despite Palestinian claims. :)
