Description
This policy brief assesses escalation risk in protracted missile exchanges during the U.S.–Israel–Iran conflict, using IRGC Operation True Promise 4 (Waves 1–13) as the empirical frame. It argues that escalation risk is driven less by average strike performance than by cumulative probability dynamics and the possibility of a single low-probability, high-impact strike against a critical node.
Abstract
This policy brief evaluates low-probability, high-impact escalation dynamics in protracted missile exchanges based on open-source reporting and cross-validated indicators concerning IRGC Operation True Promise 4 (Waves 1–13). It finds that estimated interception rates remain relatively high, no independently verified systemic military degradation has occurred among principal actors as of Wave 13, and the conflict remains below confirmed strategic escalation thresholds. However, prolonged launch tempo, interceptor consumption, and critical-node exposure can generate cumulative probability dynamics that narrow the margin of stability over time. The brief combines operational assessment, bounded cost modeling, critical-node escalation scenarios, and threshold indicators to clarify why apparently contained exchanges may still carry nonlinear escalation risk.
