Terrorism in the United States

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

    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.

    Why Aren't There More Terrorist Attacks Like the One in London?

    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.
