Never said they were boyscouts but it sure seems like there was more honor. I know my father would never even have thought about pissing on a dead body in WWII.
Let me ask you this. Do you think they should have pissed on them? What punishment should they receive? And if it were your brother who was pissed on, would you seek revenge?
I don't think they should have pissed on them, but I can understand why they did it. I was in the Military for 7 years and did 2 deployments to the Middle East, I was never in direct combat but I served with people who were, when you are sent on multiple deployments you end up dehumanizing your enemy in order to be able to successfully kill them and survive, this is something civilians have trouble comprehending apparently. No disrespect to your father but if he did piss on a dead Jap or Kraut, you think he would tell you about it? nobody who's really been in the shit likes to go around talking about it.
As far as the punishment for these Marines, I think they should be given a stern talking to and a refresher course on the ROE's and Geneva conventions.
