Great interview! Thanks for posting.
I visited Dachau when I was stationed overseas. Of all the experiments they did one was to see how few calories a person could survive on. The barracks were so cramped they couldn’t just slide into bed. It was hard to imagine the evil that went on there. They still had some of the ovens intact. There were several mass graves that had the remains of over 10,000 people - each.
We can never forget.
