I don't know what you thoght when typing up the post, but I do know what I understood when I read it.
A one-state solution is "never" going to work because that's the current solution. There's one state of Israel and no state of Palestine. And currently, Israel hasn't show itself to be all too nice to the palestinians, what with the settling, apartheid and recently as transparent genocide as it gets.
What a one state solution will do is keep the current oppressive power structures. Meaning nothing will truly change. The Israeli press has shown itself to be very anti-Palestinian, and a lot of the population is indoctrinated to think Jews are entitled to settle the land at all costs towards the Palestinians.
There are a lot of examples on YouTube of 'regular' Israelis talking of it in the most gruesome and off-putting words imaginable. One might call it cognitive dissonance, but it's pure indoctrination.
And breaking such indoctrination, cultivated potentialy since the dawn of the sigle state, takes both time and effort.
Effort which is most lukely to succeed were the Palestinians given their own, fully autonomus, UN-recognized and in all aspects equal state free from Israeli control of all types.
Why?
Because Israel has shown itself to be unworthy of having authority over Palestinians.
Systematic oppression needs an equally systematic way of undoing it. Any attepmts at molding the current power structures are unlikely to stop the mistreatment of Palestinians.
The current Israel was and continues to be a one-state solution. A failed solution, that lead to the current genocide. The only way in which such a solution would work is through radical changes to the power structures of the current State, or a new one altogether. One with new laws, a new government, artificially made to overrepresent Palestinians to try to undo the equally artificial, but ingrained in Israeli society opression of them.
Previous such solutions have had a very bad success rate. Such an artificial state is truly like a house of cards. A bad compromise. Neither side is happy for a long time - both feel entitled to more than they get.
So in my humble opinion, one could say that Israel has been given a chance to govern the Palestinians. What they ended up doing is commiting systematic opression a d as of late, a very transparent genocide against them.
If you ask me, any goodwill they've gotten to that end was rescinded as of late, and anything less than a two-state solution will be rewarding the perpetrators.
Obligatorily: I'm not saying that Israelis are all genocidal maniacs, or activelly commiting genocide. But the state, their state, is. And such a state cannot reasonably be expected to stop of its own accord or by a finger-wag from the UN. Since the figer-wagging has been done consistently for quite some time now, way before the recent escalations.
