The Islamic State (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.

    Stabilizing Eastern Syria After ISIS

    Sep 8, 2020

    Eastern Syrian communities are no longer occupied by ISIS but they are in a fraught political environment where the Syrian Democratic Forces and the Syrian government have both expanded their presence and some ISIS fighters remain. What are the region's most urgent needs and is there a viable strategy to build near-term stability?

    Airpower Was Indispensable to Defeating ISIS

    Feb 5, 2021

    Some argue that airpower could have been applied more vigorously in Operation Inherent Resolve to have more quickly defeated ISIS. Airpower was essential, but ground forces led by Iraqi and Syrian partners were needed to destroy the Islamic State as a territorial entity.

    ISIS Could Rise Again

    ISIS has a tried-and-true playbook for bringing itself back from near death. Just a few years ago, it managed to resurrect itself after apparent defeat. And the history of that resurrection should serve as a warning of what may be coming now.

    The Philippines is a long way from the Islamic State's birthplace in the Middle East. But the jihadis have already seized and held a city there for three months. Even if the Philippines doesn't become a major node in the Islamic State's network, it will likely remain fertile ground for supporting the group and its violent agenda.

    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.

    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.

    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.
