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.

    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.

    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.

    Salvaging Iraq

    The Iranian government, particularly the Revolutionary Guards, is playing a huge role in helping the Iraqi security forces fight the Islamic State. Iraq and Iran share a 910-mile border that is mostly porous. Iraq's territorial integrity is critical for Iran too.

    Why al Qaeda in Yemen Attacked Paris

    The bloodshed in the Paris offices of satirical magazine Charlie Hebdo was a startling reminder of al Qaeda's ambitions, capabilities, and ruthlessness. And whether or not the attack was planned as a marketing device to help al Qaeda emerge from the expanding shadow of the Islamic State, it may be having that effect.

    When Jihadis Come Marching Home

    The existing pool of determined jihadists in America is very small and lacks training and experience, which fighting in Syria and Iraq would provide. Returning jihadi veterans would be more formidable adversaries. Still, the threat appears manageable using current U.S. laws and existing resources.

    ISIS in Perspective

    While ISIS poses a threat to the U.S., violence from the group is not likely to be aimed directly at the American homeland any time soon, according to a panel of experts who discussed the Middle East at RAND's Politics Aside event. But an attack could be mounted against the U.S. if ISIS were to establish a nation from the territory it holds in Syria and Iraq.

But the idea that the U.S. would make additional concessions to Iran in the nuclear negotiations because of the anti-Islamic State group effort is not based on realities on the ground.

A reassessment of the workshop's findings shows that while a regime victory now appears to be likely, it would not be as big of a blow to ISIS due to the group's territorial gains in Iraq.

The Islamic State will bring in an estimated $100 million to $200 million this year.
