Turn on the radio in Belgium and you get news of the terrorist attacks in French and in Dutch. Belgium is divided into Dutch-speaking Flanders and French-speaking Wallonia. There's a German-speaking area, too.
To make things more complicated, Brussels, the capital, is subdivided into 19 municipalities, each with its own government. And there are six local police forces.
It all adds up to a decentralized system, a dismantled federal state. And in light of last week's attacks, some have even gone so far as to suggest Belgium is a failed state.
