Proxy wars are still under-represented in conflict research and a key cause for this is the lack of conceptual and terminological care. This article seeks to demonstrate that minimizing terminological diffusion increases overall analytical stability by maximising conceptual rigor. The argument opens with a discussion on the terminological ambivalence resulting from the haphazard employment of labels referencing the parties involved in proxy wars. Here, the article introduces an analytical framework with a twofold aim: to reduce label heterogeneity, and to argue in favour of understanding proxy war dynamics as overlapping dyads between a Beneficiary, a Proxy, and a Target. This is then applied to the issues of defining and theorising party dynamics in proxy wars. It does so by providing a structural-relational analysis of the interactions between the above-mentioned parties based on strategic interaction. It presents a tentative explanation of the proxy relationship by correlating the Beneficiary's goal towards the Target with the Proxy's preference for the Beneficiary. In adding the goal-preference relational heuristic, the article advances the recent focus on strategic interaction with a novel variant to explanations based on interest, power, cost-benefit considerations, or ideology.
