It is strange and disturbing to see so many posts on social media that deny it's a war crime to stage a surprise attack on civilians (including murders, kidnappings, and rapes) or to starve out a civilian population (by cutting off electricity, food, and water).
These are both obviously war crimes and should be discussed as such.
