Why do some people think that there is going to be a second holocaust?

It is because of Jewish success that the first holocaust happened if you remember correctly. In Germany, many of the people prior to the rise of Hitler were in shambles, however a large portion of the successful in Germany at the time were Jewish. This gave Hitler and his followers a platform to blame the Jew for the problems of Germany, which was highly successful. I don’t think it is a coincidence that you hear the same hateful rhetoric coming from many Muslims in the Middle East as well as around the U.S. directed at Israel.
