The World Must Never Forget, lest it be repeated.
Holocaust Memorial Day (Yom Ha-Shoah)
Videos and photos are graphic and disturbing, but necessary in order the world never forgets. Should they forget, it will happen again.
While stationed in Germany in the early 1970's, I took the time to visit Dachau and walk through it. Cleaned up, all but 2 barracks torn down and those 2 newly constructed, memorials hosted by every group who met their fate there and massive graves of unknown people still leave an impression on a person.
In comparison, Dachau wasn't near as gruesome as was other camps like Auschwitz, Treblinka and others.
Eisenhower was right to command it be documented as we all know, many today try to claim it never happened.
