The exact name of the organizations running the guerrilla war can change, and it probably wouldn't change the situation very much. What needs to happen to actually change the status quo is the Palestinians giving up on the generational dream to reconquer Israel through armed combat. And I dont think there is actually any reasonable concessions Israel could make that would spur this to happen.
I mean, I am sure a lot of Western and Arab nations would be happier if Israel stop colonizing the West Bank with their own right wing wackos. But I dont think this has appreciably altered the Palestinian political project of reconquering Israel very much, one way or another. Reconquering seems to have been the political goal before, during, and probably after.
Will bombing Gaza back into the Stone Age facilitate an ideological shift, or cause the Palestinians to just give up? I really dont know. Such brutal tactics seemed to have worked with China and Xianjing, where there is no expectations that political Islam will ever create problems ever again. But I also acknowledge the fact Arabs are so racist against Jews for historical reasons and Israel having religious importance complicates matters.
But it seems pretty obvious if Israel just retreated back to the border and everything goes back to the way it was before, nothing will change.
