Today, we remember.

On Jan. 27, 1945, Auschwitz, the Nazi death camp where more than 1.5 million people were exterminated, was liberated by the Red Army.

In all, Hitler’s mechanisms of genocide killed more than 6 million Jews, plus millions of others, including Gypsies, the mentally or physically disabled, homosexuals, Jehovah’s Witnesses, Poles and Russians.

Of all the Nazi death camps, Auschwitz and its sub-camps were the largest. It was there that Hitler’s minions developed the mass-murder techniques they would use in their plans for the “Final Solution,” the attempted genocide of Europe’s Jews.

The barbarity of Auschwitz did not begin or end with murder. Thousands were used as human guinea pigs in gruesome, and often deadly, medical experiments. Hundreds of thousands were forced into slave labor to make the instruments of war Hitler used against the world.

Much has changed in the 60 years since Auschwitz was liberated. Sadly, genocide, racism and anti-Semitism remain fixtures in the world. From Sudan and across Africa, thousands die daily because the world doesn’t intervene. In Europe, there is a rising tide of anti-Semitism. And, in the United States, we have yet to heal the scars left from generations of racism and hate.

Today, we remember humanity’s capacity for evil. Today, the world repeats: Never again. Maybe it’ll mean it this time.
