I think it's important to keep in mind that Israel is completely capable - at any moment - of surrendering, giving right of return, de-militarizing, opening all borders, creating a single government that fairly represents all in the area, giving reparations, and vowing to never again attempt to kill civilians. The water and electricity would come right back on.

Doing so would save the lives of countless Palestinian civilians, and if they had any care for their lives at all, they would do this immediately.
