While some structural realists and their liberal and institutionalist critics continue to fight a high-profile battle about the fundamental nature of international politics, a quieter discussion is progressing about how to integrate various aspects of realist thinking into a more coherent approach to security politics. The goal of this discussion is to marry the two major strands of contemporary realist thought: balance-of-power theory and security dilemma theory. Recent works advocate combining structural variables, such as the number of great actors in the system and the distribution of capabilities among them, with security dilemma variables, such as the comparative efficacy of offensive versus defensive doctrines given available weaponry and military training.
