War Crimes in Palistine

On Fareed Zakaria 's GPS on CNN Bernard-Henri Levy called the actions of Hamas a war crime. He said that Hamas is using the citizens of the West Bank as human shields. He is talking about reports of Hamas using the bottom floor of a hospital as a base. Is there any chance that we would see a war crimes trial on this? I think it would be great to see war crime trails for people on both sides of this conflict. I know it will not happen.
