For the last fifteen years or so the establishment political parties in Western Europe have dealt with the rising popularity of nationalist and anti-immigrant parties by forming a cordon sanitaire around them — the French term has been borrowed to describe the way all the Good People quarantine a contagion of right-wing thinking. All the non-nationalist parties refuse to form a coalition with the “right-wing extremists”, and negotiate with one another until some sort of government can be formed without them. If necessary, the center-right, the socialists, and the Greens will join together to stop the populist tide.
As far as I know, the term was first used to describe what was done to Vlaams Belang in Flanders and Belgium. Later it was applied to the treatment of Geert Wilders and the PVV in the Netherlands, and then Sverigedemokraterna in Sweden. I’m certain the same method will be used when necessary against the AfD in Germany.
And now a cordon sanitaire has once again been used against Vlaams Belang after the party won a municipal election in a Flemish town.
