Sir — This refers to the editorial, “Terror re-visits Europe” (March 24). Brussels has been attacked and the Islamic State has claimed responsibility for the bombings. The terrorists picked their target well, for they managed to disrupt a city that is home to the vast European Union bureaucracy.
The rise of the Islamic State has made the job for police personnel all the more problematic as they are unable to keep tabs on all potential jihadis For decades, European diplomats and leaders have lectured the rest of the world on how ethnic minorities must be treated; now the very same European elites find themselves in a trouble spot, as they have to deal with Islamist groups.
