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.

While the prospect of the Islamic State and al-Qaeda pursuing biological weapons is not zero, it is unlikely, given the difficulties involved and the availability of simpler alternatives.

    Foreign Fighters Are a Global Threat

    The threat posed by foreign terrorist fighters cannot be resolved by the United States, or any ally, working alone. It calls for broad international cooperation on law enforcement, intelligence sharing and other areas for many years to come. The road ahead will be hard, but it's best to begin now with action by the UN Security Council.
