These rules are generally made by people who don't actually know what it's like to be in a war. From what I know from the people who actually have been in one, there is no humanity in it. My grandfather can hardly speak of Vietnam. If I am called to fight, I will not be thinking "I better not shot him in the kneecap, that might hurt and that wouldn't be very nice," or any other absurd reasoning they might have for these idiotic rules.
The point is to kill and capture territory.
The above in bold is an important statement.
I've never been in a war, I did think about joining the Navy after I left high school but that was more because I was always one of those athletic nuts who found running and working out and pushing myself to the limits to be a great thrill.
I don't know what war is like outside of what I hear from people I know who have fought in them, what I read and what I see on tv.
I generally don't answer questions like the ones posed in the OP because I don't know. I think people have a right to protect themselves and I think those who actually put their lives on the line are the ones who are qualified to make the decisions on what kind of weapons they need to do so.
Ideally war should not exist, we should find another way to solve our disputes. If that's not possible then we should fight wars according to strict rules dealing only in what is humane.I think people get caught up in the ideal scenario, that's how they want things to be and they try to make rules accordingly. Realistically things aren't usually packaged so neatly.
