Domestic Terrorism

Featured

Domestic terrorism involves violence against the civilian population or infrastructure of a nation—often but not always by citizens of that nation and often with the intent to intimidate, coerce, or influence national policy. RAND addresses national security and critical infrastructure needs through objective research that helps government agencies prevent and mitigate terrorist activities and improves disaster preparedness, response, and recovery.

    The Origins of America's Jihadists

    Dec 4, 2017

    American jihadists are made in the United States, not imported. Homegrown terrorists have accounted for most of the jihadist activity in the U.S. since 9/11, with most of those who carried out or plotted terrorist attacks either born in the U.S. or arriving as children.

    Trends in the Draw of Americans to Foreign Terrorist Organizations from 9/11 to Today

    Dec 18, 2018

    The Islamic State of Iraq and the Levant (ISIL) has been more successful than its predecessor organization, al Qaeda, in drawing Americans to its cause. Americans drawn to ISIL are more likely to be younger, less educated, Caucasian/white or African American/black, and to have been born in the United States.

    How to Strengthen Terrorism Prevention Efforts

    Shortfalls in national terrorism prevention efforts have come not only from limited programmatic focus and resource investment, but also from critics seeking to constrain or halt such efforts. The most effective path for the U.S. government would be to support state, local, nongovernmental, and private terrorism prevention efforts rather than building capabilities itself.

    National capabilities for terrorism prevention, which refers to options other than traditional law-enforcement action to respond to the risk of individual radicalization to violence, are relatively limited. Most rely on local or non-government efforts, and only a subset receive federal support.

    Islamic State Proves Greater Draw for U.S.-Born Recruits Than al Qaeda

    The Islamic State of Iraq and the Levant (ISIL) has been more successful than its predecessor organization, al Qaeda, in drawing Americans to its cause. Whereas al-Qaeda was more reliant on preexisting connections to the region or Islam, an ISIL candidate recruit is more likely to be younger, less educated, and a U.S.-born citizen.

    By continually staking claim to big and small terrorist attacks, regardless of target selection or casualty count, ISIS has attempted to instill a sense of omnipresent and unpredictable danger. And in the process, terrorism fatigue may be setting in around the world.

    The number of attacks like the one on London Bridge are low because jihadist ideologies have failed to gain traction in most Muslim countries, and it's difficult to recruit people remotely. Supporting violence and participating in it are two different things.
