I am confused which side of this tsunami you have in mind? Do you mean tsunami of mass Muslim immgration which leads to the attacks on French Jews? Or do you mean failed "tsunami" of Le Pen who tried to limit this Muslim invasion? Which of the two is bad for the French Jews?
I think that French Jews who are for the open borders and diversity should move to the Lebanon (French language is still being used there).
The "political tsunami" I spoke of and this character quoted was the anti-immigration populist wave sweeping over the entire developed world.
