The Islamic State of Iraq and the Levant (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.

    Can the Islamic State Survive If Baghdadi Is Dead?

    Jun 30, 2017

    If and when self-declared Caliph Abu Bakr al-Baghdadi is killed, it will have little effect on the threat posed by the Islamic State to global security. The far more important objective is to continue dismantling the organization as a whole, including its affiliates in Libya, Egypt, Nigeria, and Afghanistan.

    How to Achieve Stability in Iraq After ISIS

    Jul 24, 2017

    After major combat operations against ISIS in Mosul, recovery and stability will require redoubled efforts by Iraqis and the international community. How well humanitarian, security, and other needs are addressed will affect the immediate stabilization of Iraq, including whether civilians can return home.

    America Is Great at Fighting Terrorism, but Terror Is Alive and Well

    When terrorists adopt a strategy of pure terror, it is challenging to prevent attacks like those seen in Nice, Columbus, London, Barcelona, or New York. Instead, strategies are needed to counter terrorism's ultimate aim, to instill fear, and to remove some of the incentives of those who might be motivated to conduct them.

    Why Africa Could Provide an 'ISIS Renaissance'

    ISIS has been one of the most formidable and well-organized terrorist groups in history and it would be naive to assume that ISIS will simply cease operations in the face of recent losses. More likely, the group, along with its many followers, will attempt to disperse to a new base, and parts of Africa are likely targets for a new caliphate.

    Russia's Approach to Counterterrorism and Counterinsurgency

    The United States and Russia have both suffered at the hands of Islamic militants. But any attempts by Moscow to compare its campaign against jihadists with America's war on terrorism are inaccurate. Russia's brutal methods have often made things worse, so the United States shouldn't view Russia as a viable counterterrorism partner.

    ISIS's oil revenues declined from a peak of $40 million per month in 2015 to $4 million per month as of early October 2017. Despite the massive reduction, it's still a substantial amount of money for a group whose expenditures decrease with the size of the population and territory it controls and decreased recruitment.

    Al Qaeda in Syria cut ties with its parent organization to portray itself as a legitimate, capable, and independent force in the Syrian civil war. The group appears dedicated to helping Syrians prevail, and now that ISIS has lost its capital in Raqqa, al Qaeda may be the only group viewed as militarily capable of challenging the Assad regime.

    How Will Authorities Know When Foreign Fighters Have Returned?

    As the Islamic State's territory shrinks and its prestige declines, militants will try to find their way home. Many foreign fighters began as criminals, and many might turn to crime on their return. One of the most productive ways to identify and disrupt returning fighters is to focus on the criminal underworld.
