WHAT?! Where would you hear this? There are over half a million jews in France! It is the 3rd largest Jewish country in the world. A large majority though from a survey said they want to leave. I have a French Jewish friend who says he feels safe there but some are wanting to leave. French law does not allow surveys to ethnically or nationally identify people. However, this will most likely cause France to be overran by Muslims and when antisemitism does peak there may be no way out.
No, there is a far larger number of ethnic Jews in Russia than in France.
Also the French Jews are mainly not Ashkenazi (although some in the video are).
They are mainly Mizrahi Jews, from North Africa.
