The so-called Islamic State has different strategies in different parts of the world, but in Africa and in Europe, certainly, its core objective is becoming clear: to kill Christians. Its long-term goal: to provoke a new Crusade, reviving the holy wars of many hundreds of years ago in the belief that this time around Islam will win. In practical terms, this focus on a single pervasive, easily targeted enemy is useful to a “caliphate” under pressure that is trying to keep its troops in line.
