I always tear up at that episode.
You're right, lest we forget and history repeats itself.

Good to know I'm not the only one who tears up.

At this time 70 years ago my father was liberating Dachau with his unit as a 24 year old 1st Lieut. AAA in the 7th Army. He was in the Rhineland Campaign and the Army of Occupation. For taking over when his column was crossing a border and spotted and fired on by German 88s, he was awarded the Bronze Star. I have his medal and it is my avatar.

12 million went through the concentration camps.

6 million were Jews
6 million were political prisoners, prisoners of war, Roma, Gays, sympathizers, etc.

We tend to focus on the number of Jews, because this truly began as a Jewish solution, but it conveniently worked on many other classes of society as well.

My Dad was a tail-gunner in a B17...and to the day he died, he choked up at the very mention of Nazism. The real horror of Hitler and the Nazis was they were, in a sense, nipped in the bud. It all happened in a few years. What if they had won the European war, and had the time to create "mature Nazism"--the same length of time that, say, the Soviet Union was given? What could Hitler, Himmler, Heydrich, Eichmann, Mengele have accomplished had they had the time that Stalin and Beria had? A second Wannsee Conference, for starters--to make lists of American Jews? Palestine purged? Africa turned into one giant slave state/charnel house, a super Belgian Congo? Thank God for the fortitude of the people of the world, especially the Russians, that they stopped this madness.

It was an on-going process, not an overnight event. Soon, they will all be gone.
