Everything you’re saying really just supports the fact that the nations of the time were handling the situation in a wildly immoral way, and the creation of Israel as an ethnostate was part and parcel of that immorality, and remains highly consequential to this date.
There’s no point asking me as an individual how I would personally have solved the crisis if I could travel back in time, because one person can’t unilaterally force a nation to do anything without being a dictator, and people don’t become dictators without doing horrible things.
What matters is recognizing that the Israel of today came to exist out of two factors:
Wealthy and influential Zionists wanted to claim Palestinian land by any means possible to further enrich themselves.
Other nations wanted somewhere to send as many Jewish people as possible because they were antisemitic and didn’t like refugees.
Now we’re stuck dealing with the consequences of our idiot racist ancestors. Let’s just try our best to not be overtly idiotic or racist ourselves (racist, for example, by turning a blind eye to the genocide happening to Palestinians, as if they’re not even human beings, or idiotic by thinking that there’s any justification for Israel’s insanely disproportionate use of force).
Just to be clear, I’m not accusing you specifically of being racist or idiotic, I’m just describing my general position on things.
