The question of the outcome of the war is a reasonable one. That said the primary goal of the war is to ensure the security of Israel. The longer term outcome would depend on political processes in Israel and in the Palestinian side and likely all the other parties that are have been meddling in this conflict forever.
I don't personally know what's reasonable or not here to be honest, but I do know the differing opinion on it is a major contributor to the discourse and the disagreements around it.
I wanted to point that out, because you and another commenter were not able to convince each other, and this is why in my opinion.
