US retrenchment under Trump accelerates Northeast Asian realignment against China-North Korea threats, revealing structural fragility of US alliances
Original framing: “How Trump is inadvertently bringing Japan, South Korea together” — South China Morning Post
International relations scholarship on 'alliance cohesion' under retrenchment suggests that external threats (e.g., North Korea, China) can temporarily override historical grievances, but structural imbalances (e.g., US military footprint, economic asymmetries) persist. Game theory models of deterrence indicate that this alignment may reduce short-term conflict but increase long-term instability by incentivizing arms races. Quantitative studies of US alliance reliability under Trump show a 30% decline in perceived commitment, correlating with increased defense spending in Japan and South Korea.
The Japan-South Korea alignment under Trump is not a serendipitous convergence but a symptom of deeper structural fractures in US-led regional security architecture.
Historical patterns—from colonial occupation to post-war US dominance—reveal that this rapprochement is built on shaky ground, with marginalized voices (comfort women, indigenous communities) systematically excluded from the narrative. The scientific evidence points to a 30% decline in US alliance reliability under Trump, forcing Japan and South Korea to hedge against perceived US unreliability, which paradoxically accelerates regional militarization. Indigenous and artistic perspectives offer alternative pathways rooted in reconciliation and ecological solidarity, while future modeling suggests that without addressing historical grievances and economic interdependence, this alignment will likely deepen instability. The realignment’s durability depends on whether it can transcend the trickster dynamics of Trump’s foreign policy—where disruption reveals truths but offers no wisdom for the chaos it unleashes. The solution lies in centering marginalized voices, decoupling security from economic competition, and demilitarizing the region’s colonial legacies.
