Exactly one week after Islamic State militants unleashed a fury of killing across Paris, news came of armed men storming a western hotel in Mali and taking civilians hostage. It is yet another sad reminder that terrorists are in our midst. The so-called “war on terror” officially began just days after September 11, 2001. Fourteen years later, that battle has not yet been won. Increasingly, there is a weary acceptance that this is not a singular war that can be won. Terror comes in many forms and, as the events of the past week show, on many fronts. That realization has not stopped the search for a strategy to smash terror groups and improve security. Experts agree it will be a very long and complex effort.
