Winners decide the righteous side of the war ex post facto. Allied soldiers under orders committed atrocities against innocent civilians as well. Unless we're willing to prosecute our own veterans who partook in the Dresden fire bombings or the guards at our Japanese internment camps, it seems hypocritical to prosecute a soldier whose assignment was the camps UNLESS we can prove that that specific individual acted with cruelty or gave orders to do so. I guess what I'm saying is, my support of prosecution would be based not on the guy's job (because he might not have enjoyed working at the camp and feared reprisal against his family or might have done his best to aid the suffering there, or, hell, he might have just been the guy who cleans the shitters. Part of the nature of conscription is the lack of choice, and prosecuting someone for something they were forced to do is ethically wrong), but on what he did beyond his job that would be a war crime. Did he work chow hall or did he serve as a personal assistant to Mengele? Did he treat prisoners with dignity or rape them in his free time? To what degree was he coerced? For what did he use his limited autonomy? And most importantly, what can we prove beyond reasonable doubt this many years later?
