Lest We Forget the Famine: We need to mark our Holocaust

On this day 72 years ago Soviet troops reached Auschwitz. That army discovered depravities that once seen could never be forgotten. This date was chosen to mark Holocaust Memorial Day in many other countries.

Today’s reflective ceremonies recognise that atrocity is a recurring failure. Those events will remember genocides in Cambodia, Rwanda, Bosnia and Darfur. That Aleppo might be added to that harrowing list shows how despite our best efforts, our capacity for savagery remains undiminished.
