Couple of points:
1. Yes, folks act badly in every war. US soldiers even act badly in war. That should not be tolerated.
2. Unlike many BS ROE restrictions and touchy feely crap, rules on the treatment of POW's have a very real effect on the war. Torturing and maiming POW's is how you end up with armies not surrendering even when they have lost, and really brutal outcomes. There are solid reasons to treat your prisoners correctly, even if your opponent is not.
3. It's becoming pretty clear that NATO (us) is going to get sucked into this bullshit conflict sooner or later. I would prefer not to have to shoot an "ally" in the face because they have made a habit of committing war crimes.
4. Again, we don't have to pick a side here. Bad and Not-as-Bad are fighting, due to bad government. That's no reason to be "OK" with 18 year old draftees being kneecapped because they avoided being shot by their Замполит. *
