DAESH (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.

    How to Roll Back ISIL and Other Terrorist Threats

    Sep 30, 2016

    ISIL is the most active group among Salafi-jihadists, waging a wide campaign. Defeating the group will require moving it from a quasi-state to an insurgency to a suppressed movement that controls little or no territory or population.

    Countering ISIL as a Transregional Threat

    Jan 31, 2017

    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.

    The Need for a Targeted Counter-ISIL Strategy

    Defeating ISIL is only possible if political conditions change in the Middle East, North and West Africa, and South Asia, and in ways that are exceedingly unlikely. The coalition should focus on reducing ISIL's ability to conduct attacks and on removing the underlying conditions that feed Sunni grievances.
