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.

    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.

    Obama's Iraq Dilemma

    On the surface, President Obama faces a classic foreign policy dilemma: The Iraqis are asking for U.S. military assistance to halt ISIS's dangerous offensive, but Obama has long promised the American people that he would withdraw the U.S. military from involvement in Iraq.

    Key to Iraq May Rest with Syria

    The answer to the fighting and instability may lie in a settlement which includes negotiating with Syrian President Assad, perhaps brokered through the Russians and Iranians. As unpalatable as it may be to the West, such a settlement would acknowledge the political and geographical realities on the ground.

    Since 2010, there has been a 58 percent increase in the number of jihadist groups, a doubling of fighters, and a tripling of attacks by al Qaeda affiliates. The U.S. cannot afford to withdraw or remain disengaged from key parts of North Africa, the Middle East, or South Asia.

    Replacing one big al Qaeda with many smaller ones does not reduce the total number of terrorists but may reduce their overall strategic capability. For the U.S., the biggest opportunities may lie in countering al Qaeda's future recruitment and capitalizing on new sources of intelligence.

    Iraq Picture May Not Be as Bleak as It Seems

    Over the past month, al Qaeda affiliated Islamic State of Iraq and Syria (ISIS) has made a concerted effort to seize the Iraqi cities of Ramadi and Fallujah. The attacks have received a lot of attention, but ISIS does not represent a majority of Iraqi Sunni in Anbar. Many Sunni Anbari leaders continue to reject al Qaeda.

    The United States should not be too quick to write off Iraq based on recent violent trends, says Jason Campbell. After all, if there is anything that should be remembered from years past it's that the Iraqi populace can endure astonishing levels of violence and still maintain confidence in the survival of the state.
