Dachau has been my own lifelong point of no return. Between the moment when I walked through the gate of that prison, with its infamous motto, 'Arbeit Macht Frei,' and when I walked out at the end of a day that had no ordinary scale of hours, I was changed, and how I looked at the human condition, the world we live in, changed ... Years of war had taught me a great deal, but war was nothing like Dachau. Compared to Dachau, war was clean.
