| Abstract: | Increasing empirical evidence points to the existence of a monadic democratic peace. However, the quantitative literature on international conflict has yet to produce any compelling evidence that such a peace holds for one of the most prominent types of interstate force in use today, foreign military intervention. This study tests the hypotheses that democracies are less prone to intervene militarily and less likely to be the targets of such incursions. In doing so, it compares six overlapping theoretical perspectives on the monadic democratic peace. No empirical support is lent to the hypothesis that democracies intervene less often than nondemocracies, but considerable evidence indicates that democracies are rarely the targets of foreign military intervention. The latter result remains consistent across six different intervention populations from 1975 to 1996. Of the six theoretical perspectives analyzed, the institutional approach recently advanced by Bueno de Mesquita and his associates fares best. Its predictions match the empirical outcomes exactly. None of the other theoretical frameworks is even half right. In sum, it seems that democratic governance provides a barrier against foreign military intervention, but it does not limit intervention abroad. |
