If there is any lesson the human race must learn from history, this would have to be it!! The Nazis turned a large part of Europe's population from normal decent human beings, to mad butchers, willing to murder other human being in the MILLIONS,, or at the very least, look the other way, while it happened, WITH THE HELP OF THE NEWS MEDIA OF THE DAY, in a very few years, with propaganda!! Communist regimes, the USSR, Communist China, etc. did the same only BUTCHERED even more people, because they were at it longer! They just didn't get the bad publicity the Nazis did!! Propaganda is without a doubt the most POWERFUL WEAPON EVER INVENTED!! Are we being controlled by propaganda now?? You bet your ass we are!!!!I hate to use the term enjoy with those videos, but from a historical perspective, I enjoy what Yad Vashem puts out. They are a reminder of what evil can do when it is allowed to grow and fester.
