Generals in the Cabinet: Military Participation in Government and International Conflict Initiation

How does the presence of military officers in national government affect a state's likelihood of international conflict? We know a great deal about how overall regime type affects international conflict, but there is substantial variation within regime types in the participation of military officers in the government. We know little about how this variation affects a state's conflict propensity. In this Research Note, I examine three competing arguments for the effect of military participation in government on conflict initiation: Military Aggression, Military Conservatism, and Civil–Military Competition. Military Aggression suggests that military involvement in government will tend to guide the state toward conflict, given a military predisposition to favor the use of force. In contrast, Military Conservatism argues that military officers in government will lead the state to less conflict, given their personal familiarity with its costs. Civil–Military Competition holds that when military officers and civilians share political power, a variety of pathologies in national security deliberation and decision-making emerge, increasing conflict propensity. I test these three propositions cross-nationally using data on the number and type of positions held by military officers in cabinets and state councils and international conflict and find the strongest support for Civil–Military Competition.
