I was listening to Radio 4 this morning as well...and it's not the only media outlet making this point today either. The gist is that Belgium is barely a country at all; rather a collection of loosely connected municipalities held together with bits of string. There is no common Belgian identity or common language; it's all about whether you're Flemish or French-speaking. National institutions barely exist, and agencies in different parts of the country barely talk to each other, let along the agencies in other countries.
Belgium is held together by a love of cycling.
Its African Empire when I was a kid, which consisted of The Congo and Rwanda/Burundi, was a byword for how not to do things a tradition set in motion by Leopold II.
Think it was the French influence....whose dabblings in Africa are largely the indirect reasons, for the present difficultes.
