as for "war crimes'... what a bunch of rubbish.
the most idiotic thing we have ever done as a planet is put in place regulations on war/warfare....especially regulations that are so very inconsistent and absurd.
killing is perfectly fine, killing huge amounts of people is fine..causing death in a million and one horrific ways is ok.. just don't cause them any pain or hurt their feelings.
you can even kill civilians and noncombatants by the metric ton... just don't say you intended to kill them.
the whole thing is a joke.
