Why is Elie Wiesel's book "Night" relevant today?

In his book "Night", Elie Wiesel describes the horrors he had to go trough during Holocaust when Nazis took over Hungary. He was still a teenager at that time, at that experience had scared him for life. The book war written in the mid fifties the times when Soviet Union was still alive and well, and if Germany never started the war it would have been the USSR. The ideas of Lenin and Stalin weren't much different of Hitler's in its core. There was a lot of racism going on there too, and the crowd wouldn't be that hard to rise against others. The times of World War II seem to be really far away, and now we are again friends with Germany, despite all their deeds of the past. But still there is still racism and hatred in the hearts of many people. KKK is still alive in US and has quite a few members, in other countries such as Russia so called skin head organization has a lot of power and has a lot of members too. Wiesel's book is still relevant today because we are not that far from the times of war and terror when one race thought that it was superior over everyone else, and what consequences followed that we know from the book. It seems unbelievable that the fathers of German people that we can see every day on the streets of America could do something like that. They seem like everyone else, and they don't have ideas of Hitler's world domination in their blood, they are not different from us, but still their ancestors were so easy to gather together under the flag of hate. Hate to everyone in the world besides themselves. The point is that it doesn't matter what kind of people you are trying to rise against others, they could be Germans, French, Russians, Americans or anyone else-it's not that hard. I don't think many people, especially in wealthier parts of this country, realize how it sometimes could be hard to be different from the majority. It's really easy to make people hate someone, but it's so much harder to teach them to stop hating and to treat them with respect. I know that there will be more wars, but I really hope that it will be over something else than racism and crazy ideas of world domination. The message of the book is that we should be really careful not to repeat the mistakes of the past, we shouldn't let another war happen and let so many people die in the matter of few years. Wiesel could have been afraid that something similar could rise again, maybe not from Germany, but from some other country. He wanted us to learn on the mistakes of the past so we don't repeat them in the future.
