Although the goal of responses to terrorism is to deter, or decrease the risk of further use of terrorist violence, previous research has found that counterterrorism activities may actually increase the use of terrorist violence through what is termed a defiance effect. The goal of this project is to test these two competing predicted outcomes of criminal justice and military responses to terrorism in the case of five major British counter terrorist interventions in Northern Ireland from 1969 to 1992.
