Democratic Void Cycles: Echoes of January 6

Abstract

This thesis addresses a comparative puzzle: whether the January 6, 2021 assault on the U.S. Capitol produced democratic echoes in Brazil and South Korea, and why the aftershocks diverged. Evidence from media framing, elite rhetoric, and institutional indicators confirms a diffusion effect in both countries, while showing that its trajectory is conditional. Three filters shape outcomes. First, polarization sets receptivity; Brazil’s intense social and digital fragmentation primed audiences, while Korea’s partisan divide remained bounded by post-1987 procedural norms. Second, media structure governs translation; Brazil’s fragmented ecosystem accelerated permissive reinterpretations, while Korea’s gate-kept press initially treated the breach as uniquely American. Third, institutional guardrails determine speed and unity of response; delayed elite accountability in Brazil prolonged the crisis, while Korea’s parliament reversed emergency measures within hours and initiated impeachment within days. The theoretical contribution is the concept of permissive sanctions, the idea that impunity itself travels and lowers perceived costs of imitation. A three-phase Signal-Echo model links broadcast, domestic translation, and consequence, and a diffusion quotient is proposed, defined as signal strength times polarization divided by guardrail robustness. The model explains why Brazil experienced a larger and longer aftershock and why Korea’s echo was brief and corrected. Policy horizons follow directly. Brazil should institutionalize agile judicial capacity and pursue depolarization. Korea should narrow emergency authorities and require prior legislative consent for deployments in the capital. The United States bears special responsibility; timely, credible accountability at home functions as external deterrence abroad, particularly where politically framed clemency could otherwise signal tolerance for breaches.
