The Evolution of the Salafi-Jihadist Threat
November 20, 2018
Despite nearly two decades of U.S.-led counterterrorism operations, there are nearly four times as many Sunni Islamic militants today as there were on September 11, 2001. Based on a CSIS data set of groups, fighters, and violence, the regions with the largest number of fighters are Syria (between 43,650 and 70,550 fighters), Afghanistan (between 27,000 and 64,060), Pakistan (between 17,900 and 39,540), Iraq (between 10,000 and 15,000), Nigeria (between 3,450 and 6,900), and Somalia (between 3,095 and 7,240). Attack data indicates that there are still high levels of violence in Syria and Iraq from Salafi-jihadist groups, along with significant violence in such countries and regions as Yemen, the Sahel, Nigeria, Afghanistan, and Somalia.
These findings suggest that there is still a large pool of Salafi-jihadist and allied fighters willing and able to use violence to achieve their goals. Every U.S. president since 9/11 has tried to move away from counterterrorism in some capacity, and it is no different today. Balancing national security priorities in today’s world needs to happen gradually. For the United States, the challenge is not that U.S. officials are devoting attention and resources to dealing with state adversaries like Russia, China, Iran, and North Korea. These countries present legitimate threats to the United States at home and abroad. Rather, the mistake would be declaring victory over terrorism too quickly and, as a result, shifting too many resources and too much attention away from terrorist groups when the threat remains significant.
