Jihadist Terrorist Plots in the United States


This brief summarizes research on 121 jihadist plots against the United States between 1993 and 2017. Each of the plots is coded as to whether it was completed, successful, failed or foiled. These variables are independent of one another and a single plot can be coded with any combination of these variables. It is therefore possible for some elements of a plot to be failed and other elements of the same plot foiled, completed or successful.
