I contend that the cultural differences between the Flemish and Walloons within Belgium have been exaggerated to such an extent that the state government of Belgium has been paralyzed and solutions have eluded the Belgians. Reducing the fear-induced swelling of the admittedly real differences within Belgium may therefore facilitate relief from the paralysis. In other words, the added perspective from viewing the cultural differences as less traumatic can help the Flemish and Walloons to either live together or, ironically, be able to separate. That’s right—a more realistic assessment of the differences can actually facilitate the separation of Belgium into two (or three) E.U. states (or Flanders joining the Netherlands and Wallonia joining France—and the German-speaking area joining Germany). Exaggerating differences can snuff out consideration of such alternatives and enable continued paralysis.
