I agree we should be appalled by war crimes, but can you be specific about what exactly you consider a "war crime"? How would you distinguish war crimes from just regular war? Obviously deliberately killing civilians should be considered a war crime, but how much effort is required to avoid unintended civilian casualties for a military action not to be a war crime?
To me it seems a lot more like a matter of gradations and shades of gray than a black and white distinction?
Simply the fact that some unintended civilian casualties occur can't turn a military action into a "war crime," or else pretty much all war would basically consist solely of war crimes, and the phrase "war crime" would lose all its meaning as distinct from the word "war."
I don't think the Israeli army is deliberately targeting women and children. But their indifference and lack of any precaution to protect them is a war crime in my eyes.
