Don’t mistake this for any kind of humanitarian concession, this is merely yet another step toward the full ethnic cleansing they want to achieve. By making the south of Gaza slightly less unliveable than the north they intend to push all civilians into the south, and when that is done they will simply do the same to the south as they did to the north. If they get away with ethnic cleansing in one half of Gaza they believe they will get away with it in the other half too because they will have set a precedent.
