A Rose by Any Other Name: Neoclassical Realism as the Logical and Necessary Extension of Structural Realism

Neoclassical realism is often criticized by non-realists for being an ad hoc and theoretically degenerative effort to explain away anomalies for neorealism. In this paper, I argue instead that neoclassical realism is a logical extension and necessary part of advancing neorealism. Structural realism argues that the system constrains but does not determine state action and where foreign policy departs from what would be ideal behavior given a state's structural position, domestic politics and ideas are generally the cause. This focus on mistakes and maladaptive behavior, seen in such neoclassical realist concepts as over-or under-balancing, is necessary to avoid falling into the trap of merely using domestic politics and ideas to make neorealism more determinate and explain residual variance in foreign policy choice unaccounted for by structure. The article attempts to correct the mistaken presumption that particular paradigms own domestic politics and ideas, asserting instead that each paradigm has access to these variables but must make them their own.
