The Hard Power of Natural Resources : Oil and the Outbreak of Militarized Interstate Disputes

Abstract

According to conventional wisdom, strategic natural resources like oil are harmful to international peace. Nonetheless, there is little comparative work on the link between resources and interstate conflicts. Analyzing the impact of oil on militarized interstate disputes on the dyadic level of analysis for the period from 1946 to 2001, this paper shows that oil in fact influences the conflict potential between countries. Results of logistic regressions suggest that absolute oil abundance as well as oil dependence increase the risk of dispute involvement. We find that in particular oil production, oil reserves, oil dependence, and oil exports are associated with a higher risk of initiating conflict while countries enjoying large oil reserves are more frequently the target of military actions. Furthermore, our analysis indicates that the presence of large oil deposits also increase the intensity of international disputes. Relative measures of oil abundance such as per capita oil production, in contrast, do not affect countries’ dispute proneness. Increased militarization, the internationalization of intrastate violence, the indulgence of an oil-dependent world community and so-called “classical resource wars”—rather than domestic political mechanisms inherent to the rentier state—are likely to explain our findings.
