If you haven’t been following this story, now might be a good time to look into it – Belgium may be dividing into two separate entities sooner rather than later, with Brussels possibly becoming an independent city-state in the process:
Belgium is the host country for the EU project, and the bureaucrats in Brussels are terrified that the epicenter of European anti-nationalism may be about to break apart due to national differences. Also, free-market-oriented Flanders, where 60-percent of the population lives, generates 70-percent of the national wealth, effectively subsidizing socialist-leaning Wallonia. So the move to partition carries powerful economic lessons as well. If Belgium does break up, Brussels, the capital of Europe, could become an independent city-state. It would also be the first Western European state with a Muslim majority.
