IMHO what is possible is perhaps a breakaway small nation such as Cornwall or Brittany, seeking to protect their people from outsiders, both European and non-European. So such a policy would not be explicitly racist.

Places like France and England are on a different magnitude. Their bigger size works against them. Smaller nations / businesses / groups are quicker and more pro-active in making things happen. What is happening in Belgium is a big political shift which the ruling classes perhaps did not foresee. So I suppose there is hope.
