Balancing Shadows

How Realism Frames Power and Survival Across the Pacific

Abstract

Growing competition between the United States and China is frequently framed as an inevitable great-power conflict driven by ambition, ideology, or a looming “Thucydidean Trap.” This paper challenges such interpretations by applying defensive realist theory to contemporary U.S–China relations. Drawing on the foundational work of Kenneth Waltz and Robert Jervis, as well as recent scholarship on power transitions and Indo-Pacific security, this paper argues that the rivalry is best understood as a product of structural insecurity and mutual misperception within an anarchic international system rather than deliberate expansionist intent. Using a qualitative, theory-driven analysis grounded in secondary literature and empirical cases—including alliance behavior, economic decoupling, technological competition, and regional security dynamics—this paper demonstrates how both states prioritize survival and risk avoidance over domination. The analysis further explains why excessive power accumulation is constrained by counterbalancing pressures, making large-scale war an irrational outcome for both sides. The findings suggest that U.S–China relations are more likely to stabilize into a prolonged “cold peace” characterized by competition without direct conflict. The paper concludes that conflict prevention depends not on trust or ideological convergence, but on restraint, transparency, credible deterrence, and limited cooperation in non-zero-sum domains. These insights contribute to broader debates on great-power rivalry by highlighting how fear, prudence, and balance—rather than aggression—shape contemporary international politics.
