Today is Holocaust Memorial Day. In July 2019, when I visited this museum in Washington DC, I witnessed the sight of piles of shoes. We need to know that each pair of shoes here represents a Jew who was slaughtered by the Nazis. This is the most painful lesson that history has taught mankind. We must remember this painful history - the lives and blood of the persecuted so that the next generation can learn to face each life with humility and respect. We must remember all this!
