It is already too late for most of Europe. Look at what has happened to London.
The reality is there is a two tiered West Europe today. Over large areas of Britain and France and even Germany there are few if any muzzlemen. In Britain the muzzards are spreading out but in places like Carlisle they are few and therefore very quiet and unobstrusive. London and Bradford and some of the so-called Home Counties are where the muzzards are numerous and flexing their muscles and knives. Same in France. Muzzlemen are mostly in some large urban areas. Marseilles and Paris in particular. Many Euros can then comfortably stick their heads in the sand and ignore the problem.
Hungary is not letting them in.
Other countries are slowly waking up.
