I wasn't personally there, so I just don't know about it.
Neither was I there. My brother has a client who was on duty when the USA Army went into some of the concentration camps. He was an Army Photographer. Whenever the topic comes up, this man gets a strange look on his face and declines to say more than this: "I will never forget what I saw. We had no idea what we would find". Almost 60 years later, and he won't say more than that. The look on his face is haunting.
The idea that these atrocities can be downplayed or ignored even now, is obscene. Saddam was/is equally evil. I dare not think how much more evil his 2 sons could have been in the world had they lived.
I've had friends visit Germany. They told me that when inquiring about the Concentration camp locations, the locals would get silent, and not want to discuss it. I think there is some that are shamed by what history says happened, and some that want a nazi revival over there. That is at least what I have read. We don't need a repeat of a bad situation. No matter what happened over there, it needs to be NOT repeated.
