The Tacit Rules of Iran-Israel Escalation May Be Breaking Down

Iran and Israel have traded ballistic missiles twice in 2024—April and October—then each time backed away from further strikes within hours. This cycle of measured escalation mirrors Cold War logic: costly enough to signal resolve, bounded enough to manage. But both sides now face a shift: if Israel's 86% missile intercept rate convinces planners that Iranian salvos are containable, or if Tehran concludes missiles cannot deter Israeli action, the restraint architecture collapses. The next trigger could push toward harder targets—leadership, nuclear sites—where miscalculation costs spiral unpredictably.
