The Political Effectiveness of Terrorism Revisited

Terrorists attack civilians to coerce their governments into making political concessions. Does this strategy work? To empirically assess the effectiveness of terrorism, the author exploits variation in the target selection of 125 violent substate campaigns. The results show that terrorist campaigns against civilian targets are significantly less effective than guerrilla campaigns against military targets at inducing government concessions. The negative political effect of terrorism is evident across logit model specifications after carefully controlling for tactical confounds. Drawing on political psychology, the author concludes with a theory to account for why governments resist compliance when their civilians are targeted.
