| Summary/Abstract |
This article examines the effectiveness of contemporary counterterrorism strategy in the global fight against terrorism from 2001 to 2011. We seek to maximize the comparative approach more than most existing studies by examining three tactics (killing, capturing, and defending) applied at three scopes (leader, operational, and broad) on three levels (global, movement [jihadi], and organizational [al-Qaeda and Taliban]), while also measuring effectiveness along several quantitative, qualitative, and spatial dimensions. Drawing from resource theory (and its derived analytical approaches) and empirical terrorism studies, we formulate competing hypotheses that are quantitatively tested using a dataset with several original aspects. We find that both killing and capturing can have large effects but these effects vary based on both states' and terrorists' targeting strategies. The most interesting specific findings are that drone strikes seem counterproductive for counterterrorism while renditions seem effective. However, these effects were dwarfed by those of increased defenses, which reduce attacks in the West while redirecting them to other areas in the world. While we find the theory mostly sound, though in need of refocus, we believe current policy trends foretell an increase in terrorist activity in the coming years.
