The problem with these discussions is everyone has their preconceived notions and cherry picks Pieces mamarei chazal to fit .
I can’t think of any other issue where a “Piskei Riaz” is cited as THE first Halachic source. Never mind that it isnt brogught in Rif, Rosh Rambam (halachic works igeres teiman becomes Kodehs Kedoshim to fit the agenda), Tur, Mechaber . its a Piskei Riaz!
Another great example
“The Balfour declaration (and even the UN partition plan) are irrelevant because when the zionists took over, the british were no longer baalei batim on the land.”
It is hard to imagine a reasonable person making such an argument. It is clear that halacha recognizes kivush as a form of kinyan. Britain conquered Palestine, they handed the “problem” over to the UN the Un voted to create Israel. Simple, finished.
But no for this we ignore kivush and you need permission of neighboring countries. why? Because otherwise it doesn’t fit the preconceived agenda.
I’m not trying to convinve you that you are wrong, I can’t. My point is when you see htese types of arguemnts (Especially the scond) we arent dealing with logic, rather emotion.
