Sadly the troops are only in the early stages of controlling the area and that number is going to rise a lot if the war is brought to a military completion the way politicians sound like they intend to.
If you check the figures most of the deaths were early in the war before people actually believed the IDF that they should move South. Once they did that civilian deaths dropped dramatically.
So I don't think it's in the early stages, although this ceasefire is going to restart some elements, which is unfortunate.
Hamas needs to surrender - everything they do makes life worse for Palestinians.
I don't think Hamas is structured in a way that is able surrender, especially now that its "political" wing has totally lost whatever diplomatic or local credibility it had. It only took one month for the coalition to destroy Saddam's regime but it took eight years in all to overcome the random violence and isolated terrorist resistance. Some really bad things happened during the latter part and that's what did the most damage to America.
