No, genius, read the Geneva Hague Conventions, we do it whether our enemy does or not. That said, we don’t fight stupid like the redcoats.
Our enemy has not/will not sign the Geneva Conventions. They do not operate by the GC. They haul out prisoners and shoot them, if the prisoners are lucky.
We are therefore not bound by the GC.
You are an advocate for fighting stupidly. You are smart, but you have been misled.
