Title: Decoupling the Middle East: A Structural Analysis of Security Networks and the "Line-Cutting Test"

Abstract: Traditional geopolitical analysis of the Middle East, rooted in zero-sum competition and static balance-of-power models, struggles to explain the region's current volatility. This paper introduces "Huzhi" (Interweaving) Grammar (Yu, 2026), a novel structural framework that reconceptualizes regional security as a dynamic network of interdependent nodes. By applying the "Line-Cutting Test"—a heuristic for simulating structural failure—this study diagnoses the inherent fragility of the US-led hub-and-spoke system. It then examines the Red Sea crisis and the Israeli-Palestinian conflict as "Contradictory Huzhi Entities," arguing that these are symptoms of pathological network reconfiguration rather than isolated ideological battles. Finally, the paper analyzes the Saudi-Iran rapprochement as a case of successful node-to-node rewiring, contrasting it with hegemonic stabilization models. The conclusion posits that modern geopolitical security should be redefined as network resilience, where stability derives not from the elimination of threats, but from the redundancy and adaptive capacity of the Huzhi system.
