Compare this to the situation prior to October 7.
With regard to your belief that it looks like Hamas ground forces will be destroyed, I doubt this very much. All indications are that this is not happening. Every area that Israel claims to have 'cleared' they are having to return to. Israel claims to have killed some 9000 Hamas militants, but with fatalities of around 32,000 in Gaza so far this would mean almost every one of those fatalities that was not a woman or child was a militant. That's beyond unlikely.
This attack on Gaza will be wound back long before Hamas is eradicated (and this includes the militant wing). When that happens Hamas will emerge in a better position than prior to October 7 and Israel will be in a worse position.
Hamas' stated objective of exposing Israel is being achieved. The Israeli government has been extremely naive and short sighted in this regard.
