Killing in war generally isn't unlawful.
Yes it is. Killing enemy combatants, when the Rules of Engagement permit it, isn't unlawful, but killing anyone else most certainly is.
You can't lawfully kill civillians, reporters, or even combatants who are on your own side. Even enemy combatants cannot be lawfully killed if your RoE and/or lawful
orders prohibit their killing in the given circumstances - for example if they are
hors de combat.
Yet again your oversimplification renders your position laughably wrong.
You are citing cases where you can't kill but that doesn't mean you can't kill a combatant because there are civilians that might get hurt.
I am not "citing cases" at all. And I am not seeking to show that "you can't kill a combatant because there are civilians that might get hurt", and indeed, I never said not implied that.
I am successfully showing that
your claim:
Killing in war generally isn't unlawful.
Is false.
Any conclusions you reach from that false premise are therefore baseless.
Do you have any defence of your false claim? Or the moral fibre to retract it now that you have had its falsity clearly shown to you?
It seems the answer is "No".
Or rather is "No, but I would like to deflect attention from that".
