I know it's been a few pages, but Owlbread asked about the possibility of turning Brussels into a kind of European DC, so I'm going to answer that. Warning, it's complicated (Belgium!).
So, the idea of Brussels as a European district is one that comes up from time to time, especially when discussing possible post-Flemish independence scenarios for Belgium. One of my friend even ran for a party whose platform included that possiblity. Here's why it's not going to happen.
1. In Belgium, political parties are split by language, not region. The result is that no party specifically care about Brussels, while Flemish parties focus on Flanders and french parties on Walloonia. Since both regions wants Brussels (it's the country's economic center), no party will advocate an independent Brussels.
2. Brussels is way too small. Not the actual city, but the current Brussels-Capital region. Basically, it include mostly the inner-city, while most of the suburbs and the actual metropolitan area is outside that division. They would simply not be viable at their current size. Also, since in Belgium people pay taxes where they live and not where they work, Brussels manage to generate most of the country's wealth while being the poorest region, since anyone who makes money move outside the actual regions.
There has been repeated calls to expand the Brussels-Capital region, which have been opposed by the Flemish (Brussels-Capital is entirely within Flanders, so expanding it would be mostly at Flanders' expense)
3. Everyone wants Brussels. It's an historic Flemish city, but most of its inhabitant speaks French. As such, everyone feels it has a claim to it: Brussels is actually the capital of Flanders (depite not being part of the Flemish region), while the French-speaking community recently changed its name to "Walloonia-Brussels Federation".
Feel free to point out which part of this post left you confused so I can try to explain the mess that is my country a bit better.
P.S. I'm seeing rumors on my FB that Russia is handing out Russian passport in Luhansk. Frighteningly similar to what happened in Georgia pre-2008.
P.P.S. Miljan: Are you seriously trying to say that Serbia did not conduct massacre and ethnic cleansing during the whole post-Yugoslavia mess?
