A continent like Belgium

BRUSSELS, wrote Tony Judt, is “a metaphor for all that can go wrong in a modern city”. The late historian, writing in 1999, was referring to the civic neglect that has left much of the Belgian capital, home to most institutions of the European Union, an unsightly mess of concrete and roadworks with the worst traffic in Europe. But his words could just as well apply to the string of terrorist plots and attacks that has provided Brussels, and some other Belgian cities, with a scabrous reputation as an incubator of jihadi ideology and a paragon of law-enforcement incompetence.
