Deconstructing Washington's Late-Stage Anxiety: Tariffs, War, and the "Stage IV" Crisis of America's Institutional Cycles

This paper employs the “Initial Dividend and Institutional Cycles” theoretical framework to provide an in-depth analysis of the systemic crises confronting the United States across political, economic, and diplomatic domains in 2026. The research indicates that the current turmoil in Washington stems not merely from isolated policy blunders or leadership styles, but from the structural resonance of “triple nested cycles”—the neoliberal short cycle, the post-war liberal international order medium cycle, and the American constitutional democratic long cycle—simultaneously entering the stages of dividend exhaustion and functional degradation. Against the backdrop of the democratic system’s built-in “dividend regeneration” mechanism being reduced to institutional idle-spinning by partisan polarization and prolonged capture by distributional coalitions, the high-tariff mercantilism implemented by the Trump 2.0 administration and the Iran War—bypassing constitutional checks and balances—are fundamentally attempts at institutional transition. Driven by legitimacy anxiety, policymakers are seeking to artificially manufacture “alternative dividends.” This paper argues that these radical measures fail to generate a genuine resource surplus; instead, they function as exogenous shocks that accelerate systemic attrition, signaling that America’s short and medium cycles have definitively crossed into “Stage IV” (Legitimacy Crisis and Institutional Substitution). Ultimately, this paper argues that the trajectory of this crisis hinges on whether extreme structural pressures will trigger a catastrophic systemic collapse, or whether they can compel the institutional architecture to break the lock-in of vested interests and reboot the long cycle’s dividend regeneration mechanism.
