Belgium is, again, fighting the enemy within

This morning, Belgium became the latest European country to have suffered a major terrorist attack. The scenes in Brussels serve as a grotesque reminder of the war that has not gone away. After the arrest of Salah Abdeslam, chief suspect over atrocities at the Bataclan centre in Paris last November, Belgian officials warned of the prospect of revenge attacks: perhaps spectacular atrocities, aiming at killing hundreds. They came four days later in Brussels airport and Metro — a demonstration of the jihadis’ ability to act quickly. And a reminder that their capacity for atrocity is far from exhausted.

After such an attack we can expect to be offered a blizzard of explanations, many of them erroneous. One commonly heard claim is that Islamist terrorism is a response to western foreign policy – yet few countries have been less active in foreign policy than Belgium. The harder truth is that Belgium’s problems, like those of its French ­neighbour, are primarily domestic.
