Terrorism Threat Assessment


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.

    Who Are America's Jihadists?

    Sep 11, 2020

    U.S. residents who plotted to carry out jihadist attacks at home and those who traveled or attempted to travel to join jihadists abroad represent two dimensions of the terrorist threat.

    Baghdadi's Death Will Make Global Affiliates More Independent

    Oct 28, 2019

    The recent death of Islamic State leader and self-proclaimed caliph Abu Bakr al-Baghdadi is a major blow to the Islamic State. Baghdadi held a kind of elusive charisma for the organization. He will be replaced, but this does not mean that the Islamic State will simply go back to business as usual.

    Jihadist Threat Keeps Evolving

    The lesson of the Times Square attack is that the terrorist threat posed by the jihadist movement continues to evolve. It is today more decentralized, more dependent upon al Qaeda's affiliates, allies and individual acolytes to continue its global terrorist campaign, writes Brian Michael Jenkins.
