Islamic State of Iraq and Syria (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.

    Jul 24, 2017

    After major combat operations against ISIS in Mosul, recovery and stability will require redoubled efforts by Iraqis and the international community.

    Expanding the ISIS Brand

    Since its founding, the Islamic State has consistently expanded and contracted in order to achieve its objectives. To discern how ISIS might continue to expand, it makes sense to trace Al Qaeda's trajectory, which followed a similar pattern in the 2000s.

    Where Will ISIS Seek to Establish Its Next Safe Haven?

    Many of ISIS's surviving fighters will seek out new battlefields to continue waging jihad. By coordinating with its allies around the globe, the U.S. could work to help alleviate the conditions that lead states to fail, making them less appealing as sanctuaries where terrorists can rest, rearm, and recuperate.

    Erdogan's Fatal Blind Spot

    Erdogan's tolerance of ISIS fighters in Turkey amounts to tacit approval. The danger posed by ISIS using Turkey as a staging ground could become more formidable than the threat currently posed by Kurdish terrorism. Tolerating ISIS to fight the Kurds is therefore a dangerous and myopic policy.

It's important to understand why such an “all of the above” approach would not be workable.

    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.
