Why democracies make superior counterterrorists

The conventional wisdom is that terrorists tend to target democracies because they are uniquely vulnerable to coercion. Terrorists are able to coerce democracies into acceding to their policy demands because liberal countries suffer from two inherent counterterrorism constraints: (1) the commitment to civil liberties prevents democracies from adopting sufficiently harsh countermeasures to eradicate the terrorism threat, and (2) their low civilian cost tolerance limits their ability to withstand attacks on their civilian populations. This article tests both propositions of the conventional wisdom that (a) terrorists attack democracies over other regime types because (b) liberal constraints render democracies vulnerable to coercion. The data do not sustain either proposition.. illiberal countries are the victims of a disproportionate number of terrorist incidents and fatalities, and liberal countries are substantially less likely to make policy concessions to terrorists, particularly on issues of maximal importance. A plausibility probe is then developed to explain why democracies have a superior track record against terrorists. The basic argument is that liberal countries are comparatively resistant to coercion-and hence inferior targets-because they are superior counterterrorists. Liberalism's commitment to civil liberties and low civilian cost tolerance are, in the aggregate, actually strategic assets that help democracies prevail in counterterrorist campaigns, thereby reducing the incentives for terrorists to target this regime type. These findings have important implications for how democracies can defend their liberal values and physical security in the age of terrorism.
