Offensive ideas: structural realism, classical realism and Putin's war on Ukraine

Controversy has surrounded realist explanations of the causes of Russia's war against Ukraine, particularly John Mearsheimer's charge of western responsibility. The article illustrates the variety of realist analyses of Russia's war on Ukraine, contesting the caricaturized view that blames the West, or NATO enlargement, for the conflict.Controversy has surrounded realist explanations of the causes of Russia's war against Ukraine, particularly John Mearsheimer's charge of western responsibility. This article seeks to clarify and contextualize his argument, situating it within the broader paradigm. Realism, and even its narrower offensive sub-school, offers a wide range of contrasting interpretations, depending on which major actors are studied and what characteristics they are endowed with. Like its classical predecessor, structural realism is premised on implicit views of human nature. In an effort to explicate some of these assumptions about the behavioural micro-foundations of states and their leaders, the article investigates main components of structural theory-including power differentials, 'rational' interests and states as unitary actors-and connects these concepts to base emotions like fear and anger. It argues that realists do well to differentiate between the aspirations of states and individual leaders' quest for power and status. In the same vein, reference to Russian security concerns may be emblematic of elites' perceived challenges of cultural subordination, and Putin's personal fears for the stability of his regime. Engagement with realist thought is essential, in part because of its continuing influence on policy-making (particularly in Russia) and in order to forestall improper co-option of caricaturized versions of realist arguments.
