LONDON — The word “Wahhabism” has become a boogeyman in the West, deemed responsible for the radicalization of Muslims around the world. And since Wahhabism is a strain of Islam that has its origins in the Arabian Peninsula and is the dominant religious doctrine of Saudi Arabia, that country is often viewed as the prime culprit in the propagation of violent extremism.

But blaming Wahhabism and Saudi Arabia for Islamist radicalism is a dangerous red herring. This single-cause explanation distracts from the complex political, economic and psychological reasons people join terrorist groups. In doing so, it impedes our ability to effectively fight terrorism.

Wahhabism is, in fact, a loaded, anti-Saudi synonym for Salafism, a puritanical strain of Islam that encourages emulating the “salaf,” or predecessors, the first followers of the Prophet Muhammad. Salafism has historically been apolitical and the overwhelming majority of Salafis are not violent.

Most Islamist militants have nothing to do with Saudi Wahhabism. The Taliban, for example, are Deobandis, a revivalist, anti-imperialist strain of Islam that emerged as a reaction to British colonialism in South Asia. Most members of Al Qaeda follow a radical current that emerged from the Muslim Brotherhood, a movement that defined itself largely in relation and opposition to the West and its values. While some terrorists do identify as Salafi, Islamic sects that are ideologically opposed to Salafism — Naqshbandi Sufis and Shiites, among others — have engaged in violent jihad in Iraq, Afghanistan and Syria.
