Why are there so many books, movies, documentaries, etc. about the Holocaust? Why do we keep retelling this story?
I think that this story is told over and over again because this kind of event should never happen again. To prevent this kind of problem they are told over and over again. Holocause happened for a long time and during that period, usually it was the innocent people who got killed. Also from the Holocaust some survivors were set free, who wrote, books and told their kids. This still is a big issue, and we should never forget about this horrible time, just because it might happen again...
