Sorry if it looks like I am moving the goal posts, but I am not trying to win anything or convince anyone of anything. I am trying to fight my own ignorance and that is indeed a moving target.
I just want to gather the argument a little bit since my title says “rules of war” and that includes too many things that I find too obvious and that I didn’t consider when I chose that title. Nuking whole countries at the slightest provocation, pillaging civilians, torturing prisoners are, to me, obvious evils and I don’t need the rules of war to tell me that.
I meant specifically the matter of proportionality and the existence of allowed and prohibited weapons (and I am sure there are other issues that are not jumping at me right now).
There was a recent snafu about someone (the US, Israel) using white phosphorus. Some hair splitting went on about how those are incendiaries in some cases but have some other legitimate uses. If they are really evil, then don’t have them. If they are ok, then use them as needed and screw the gray areas.
Ditto for the new [non/less] lethal weapons such as tasers, pain rays, sonic disruptors, etc. I understand that in some cases they may produce injuries or death and are not perfectly safe. I think that is a chance I am willing to take if that means a significant advantage to my troops.
Heck, even chemical weapons if they could be somehow contained would be fair game. If a battle is in an area with no civilians and I can gas the entire enemy from above, why should I risk my soldiers? How is it different killing someone with a hole in the head or poisoned? They are dead anyways (and assuming the poison does not leave half of them alive and suffering hell)
Collateral damage is unfortunate and must be avoided, but not at all costs. Not at my own cost, for sure.
On the matter of proportionality, I say not only tit for tat, but 100 tits for tat. You shoot at me, that whole block is turned to dust. You kill one of my men, I kill 100 of yours. If that sounds too high, you shouldn’t have messed with me. If a disproportionate response is a way to bring the war to quick end, then I am all for it.
And yes, of course I understand the matters of international reproach and enemy responding in kind. Those are not moral issues though. They are practical decisions for one to balance as costs against the value of winning the war.
