Twenty-five years after the September 11th attacks, the original terrorist organization behind the 2001 attacks has been decimated by nearly two decades of American strikes, surviving only through its branches in the Sahel and Somalia. Since 2014, the Islamic State has transformed jihadist ideology into a mass phenomenon, expanding its conflict into enemy nations. Despite Al-Qaeda’s weakening, jihadism continues to prosper and maintain tension in Western societies. The threat has evolved, shifting from a centrally-organized group to a dispersed network of affiliates and inspired individuals. This evolution underscores the enduring appeal of extremist ideologies. The Islamic State’s success in exporting conflict demonstrates the adaptable nature of modern jihadism.
