NO ONE COULD blame Morocco. In 2016 the kingdom was due to host an Arab League summit, an expensive undertaking. The meetings are so dull that some heads of state fall asleep. So in February, two months beforehand, Morocco said it could not be bothered to play host. “This summit will be just another occasion to approve ordinary resolutions and to pronounce speeches that give a false impression of unity,” the kingdom said. Leaders ended up gathering in a tent in Mauritania instead.
