Today is the International Holocaust Remembrance Day. On this date, in 1945, the Soviet Red Army liberated the Auschwitz-Birkenau death camp. In a weird and unnerving coincidence, today is also the birthday of Wolfgang Mozart. That the heirs of Goethe, Schiller, Beethoven, Mozart and others could produce the Holocaust is sobering. Always remember the very thin layer of civilization that protects us.
