the stated purpose of the operation is to annihilate hamas, and that is justified. if hamas is hiding in a hospital, and that is a war crime, is it then justified to target the hospital?
you have to escape from logic a little bit here. the idf should clearly be trying to tone it down as much as it can. ultimately, however, yes; if hamas is hiding in the hospital, you blow up the hospital.
this is consequently not the time to call for a ceasefire, and the reality of the situation needs to be clarified, which is something the media is failing at: you can't hide in a hospital, that's against the rules of war, and that's exactly what hamas is doing.
