How are the Jews still relevant in Europe in the 21st Century?

Here's a thought. So the Jews have been central to Europe for the last 2000 years because of the most famous Jew namely Jesus. But as Christianity wanes in the West so does the significance of Jews.

How do the Jews remain relevant?

Well suddenly we have the Holocaust and we go from 1 Jew dying at the hands of a dictatorship to 6 million.

How interesting!
