I'm in the Flemish region. And what do you mean "occupied"?
Actually nothing really. I do not know much about Belgium's history. Just that there's two large regions in it, Flanders and Wallonia, and they sell chocolate from your country in our import stores. I was wondering what sort of reaction I'd get and the answer is not much.
What I can tell you is that if I had tried the same thing with East European or Balkan nationalists I would have been stabbed by now.
