Terrorism Threat Assessment

Featured

In light of the global increase in the number and lethality of terrorist attacks, it has become imperative that nations, states, and private citizens become more involved in a strategic vision to recognize, prepare for, and — if possible — prevent such events. RAND research and analysis has provided policymakers with objective guidance and recommendations to improve preparedness, international collaboration, response, and recovery to this global threat.

    For U.S., Many Options but No Clear Path in Middle East

    Mar 6, 2017

    The struggle against jihadist terrorism has a long way to go. All courses of action come with risks, but are not mutually exclusive. The U.S. could escalate the fight, attack the root causes of terrorism, reduce the ungoverned spaces where terrorists find sanctuary, work with state partners in the Middle East, or withdraw from the region.

    Al Qaeda in Syria Can Change Its Name, but Not Its Stripes

    Al Qaeda in Syria, by any name, remains a dangerous and capable terrorist organization with the ability to conduct attacks in the West. Those seeking to grapple with the threat the group poses should focus less on its names and more on its actions.

    U.S. Counterterrorism Strategy Must Be About More Than ISIS

    ISIS is a worthy candidate for eradication, but failing to also target its franchises, al-Qaida splinters, and other non-aligned groups in the Middle East, Africa, and South Asia could allow other threats to metastasize.

    The Need for a Targeted Counter-ISIL Strategy

    Defeating ISIL is only possible if political conditions change in the Middle East, North and West Africa, and South Asia, and in ways that are exceedingly unlikely. The coalition should focus on reducing ISIL's ability to conduct attacks and on removing the underlying conditions that feed Sunni grievances.
