The Jews have done their level best since the end of WW2 to bury the truth as to why the German people felt such animosity against them. The general explanation, if it can be called that, is that Germans were just really, really racist and bigoted and prejudiced and anti-Semitic, and decided to hate the Jews no good reason at all. Sometimes Jews suggest that they were made into a "scapegoat" -- which, by the way, is a Jewish concept and something out of Jewish history, i.e., something Jews did.

The reality is that Germans resented and hated the Jews because the Jews profited and benefited hugely at their expense. The Jews took control over Germany after the end of WW1, destroyed the German economy through greed and corruption, and let ordinary German Christians starve in the streets. When the Jews tried to assume total and absolute control through communism, Germany reacted in its own defense with Nazism. Naturally, the Jews used the media to demonize the Nazis, and have never ceased doing it.
