​​​​​​This article draws from structurationist and symbolic interactionist sociology, seeking to build a bridge between the realist–liberal and rationalist–reflectivist debates in the field of international relations. In doing so, it argues against the neorealist claim that self-help is given by anarchic structure exogenously to process. It further argues that self-help and power politics do not follow either logically or causally from the anarchic structure of the international system, but are generated by process rather than by structure. There is no logic of anarchy apart from the practices that create and instantiate one particular structure of identities and interests rather than another. Self-help and power politics are institutions, not essential features of anarchy; anarchy is what states make of it. The article explores three ways in which identities and interests are transformed under anarchy: by the institution of sovereignty, by an evolution of cooperation, and by intentional efforts to transform egoistic identities into collective identities.
