ISIL (Terrorist Organization)

Featured

ISIS (Islamic State of Iraq and Syria), also known as ISIL (Islamic State of Iraq and the Levant), is a Sunni jihadist group with a particularly violent ideology that calls itself a caliphate and claims religious authority over all Muslims. It was inspired by al Qaida but later publicly expelled from it. RAND terrorism experts have analyzed the group's financing, management, and organization; its savvy use of social media for recruitment and fundraising; and the instability that spawned the group as a regional problem in the Middle East.

    The U.S. counter-ISIL strategy must recognize the long-term nature of the global violent jihadi threat. U.S. diplomatic and military actions should focus on reducing the appeal of ISIL and disrupting the transregional network that supports it.
