2. "The world is messy" does not excuse countless war crimes. Imagine a lawyer in the Nuremberg trials saying "well sure the defendant sent children to the gas chamber, but your honor, have you considered that the world is a messy place?"
These are all war crimes, and they are war crimes because they knowingly and actively target civilians. And honestly, at the end of the day it doesn't matter much to me whether you kill a kid by shoving them into a gas chamber or by shooting them, or by dropping bombs or napalm on preschools, because either way you've murdered a child.
