There will be no will to do this, until something really big happens. The French Left will riot if the French govt tries to crack down on the Muslims. It will take something so big that the majority of France cannot ignore that this will determine the future survival of France as France
It's not about the Jews, it's about the "infidel" West.....
I think that if Notre Dame, the Eiffel Tower, the Louvre or Versaille were blown up, the French would tackle the muslim ghettos, which would quickly become "Jenins".
Then at least the boil might be lanced, and the infection dealt with.
