Hamas fighting Israel is a clear case of asshole on asshole violence, with a lot of hapless people stuck in the middle. The best thing that could happen would be for everyone to turn the guns off and go home.
Because Israel is winning, as everyone knew that they would, they are unwilling to entertain the idea of a ceasefire.
What might change their mind is if their patron state decided that this bloodbath had gone on long enough and threatened to halt support unless they stop.
