The Holocaust was a massive crime carried out from 1939 to 1945, associated with places including Auschwitz, Bergen-Belsen, Buchenwald, Dachau, Majdanek, Treblinka, and Theresienstadt, in which millions were marched into the abyss. It stands as a warning of humanity's terrible potential for self-destruction and of the need for constant vigilance, with the conviction that some are guilty, all are responsible, and that a crime too horrible to remember is too dangerous to forget. Its message calls on people to overcome evil with good, love one another, choose life and live, and remember that only silence speaks loudly enough for the millions.
