Which borders should a Palestinian state be given?
Why do you feel that the border results of that particular war matter more than any other war (that came before, or that has come after)?
Nobody seems to be able to answer these questions without massive hypocrisy when the same logic is applied to other countries whose borders were also formed as the result of wars.
It's like there's some sort of cut-off date right after WW2 where people feel nobody should be allowed to invade anyone else.
Except for Israel, where the Arab side didn't like the result of the plan that was drawn up and voted on by the UN (even though it had far more land that they currently have) rejected it, and had all of the neighboring Arab countries invade Israel literally the day after the British withdrew as their mandate to handle the area ended. They initially took a bunch of land before Israel threw their asses out and recaptured even more territory, and the Palestinians have been fighting about the results ever since.
No, instead it's Israel's fault for fighting back against the constant violence from Palestinians (mostly funded by external sources from Arab countries)
Does it suck that Palestinians are dying? Yes. Did they lose a war they started? Yes Did they choose to continue violence after they lost? Yes
So why is Israel the bad guy here?
If Ukraine retakes their territory, including Crimea, are we going to call them the bad guy if they continue to kill Russians who keep attacking them across the border? Would we call them the bad guy if they push into Russia a few kilometers to establish safer borders for their people?
