Jew hatred is still, to this very day, a powerful tool used by world leaders to whip up support. For whatever reason the gentile world has a yearning desire to rid the world of us Jews. I do not believe we do anything in particular to cause this hatred and it is a hatred which is inspired by the divine hand of Hashem. What is going on in Europe today echoes the very same antisemitic attitudes of the 20s-40s in Europe.
