Realism Is Unrealistic

Foreign Policy | Matthew Kroenig

Political realism as an international relations framework consistently fails to account for United States foreign policy behaviors, particularly regarding post-Cold War hegemony and grand strategic decision-making. Despite realism's focus on material power balances and rational state behavior within an anarchic international system, Washington's actual actions frequently deviate from structural predictions through ideological commitments, institutional expansion, and democratic internationalism.

This persistent analytical disconnect highlights fundamental flaws in classical realist assumptions when applied to unipolar or hegemon-led international orders. Consequently, defense strategists and foreign policy planners face growing operational friction when utilizing structural realism to predict alliance cohesion, power projection, or systemic balance-of-power dynamics in contemporary geopolitics. Washington's historical preference for value-driven alliance frameworks like NATO over strict realpolitik balancing forces a reevaluation of traditional security doctrines. Ultimately, overreliance on realist paradigms risks miscalculating how state power is operationalized across contested strategic theaters.

Comment

Structural realist models that assume states act purely on power-maximising incentives fail when confronted with Washington's commitment to multilateral institutional binding. The historical expansion of NATO under the 1949 North Atlantic Treaty demonstrates how ideological alignment routinely overrides classical balance-of-power logic. Rather than retrenching post-1991 to avoid offshore balancing costs, American defense doctrine consistently prioritised institutional enlargement over pure material risk reduction.

This doctrinal disconnect creates operational blind spots for security planners attempting to model coalition behavior. Relying on offensive realism theory to forecast force disposition leads to inaccurate predictions regarding deployments across international theaters. Consequently, operational readiness metrics focused solely on hardware counts misjudge how United States European Command maintains forward defense postures.

Strategic Question for Discussion

If structural realism consistently fails to account for NATO expansion under the North Atlantic Treaty, how should military intelligence frameworks assess whether future force commitments in Europe are driven by material threat changes or institutional momentum?

The pattern suggests that force disposition assessments benefit from incorporating institutional path-dependency alongside threat-driven material balancing. Incorporating coalition governance mechanisms into predictive intelligence models provides a clearer signal of sustained troop presence than hardware ratios alone. The available evidence points toward treaty obligations acting as structural drivers that persist regardless of shifts in the underlying regional power distribution.
