Do democracies behave differently from non-democracies when it comes to foreign policy?

The question of whether democracies behave differently from non-democracies is a central, and intense, debate in the field of international relations. Two intellectual traditions — liberalism and realism — dominate. Liberals argue that democracies do indeed behave differently, while realists insist that regime type and ideology are of little relevance in understanding foreign policy behavior. Arman Grigoryan, a faculty member in the Department of International Relations at Lehigh University has contributed to this debate with a recent article in a top journal, International Security.
