The war called by Israel “Swords of Iron” began with an unprecedented surprise attack by Hamas that led to the death of hundreds of Israelis and the abduction of dozens more. The Institute for National Security Studies (INSS) is following the events carefully, providing situation updates and policy recommendations for decision makers and the general public.

28.06.25Why Deterrence Failed on October 7, 2023?
Israeli policymakers have relied on cumulative deterrence strategies to combat terrorism. However, Israel has consistently failed to deter Hamas’ attacks, not only on October 7 but also in 2008-09, 2012, 2014, and 2021. A critical yet often overlooked observation is that cumulative deterrence strategies coupled with robust denial capabilities can lead to an attrition trap, which serves as a victory strategy for weaker actors, ultimately resulting in deterrence failure rather than success. This article employs lessons from cases of both successful and failed deterrence in a longitudinal study of the Arab-Israeli conflict. It argues, firstly, that in challenging contests of resolve, actors can escape the attrition trap when they move beyond cumulative deterrence strategies and employ land maneuvers that systematically target the strategies of terrorist organizations, thus addressing the credibility problem. Secondly, such wars can potentially lead to overextension and further wars of attrition, which means defenders must know when to stop and disengage, ensuring the balance of legitimacy and resolve remains favorable to them. This paper asserts that Hamas remained undeterred throughout the conflict because Israel viewed reliance on cumulative deterrence strategies and its robust denial capability, the Iron Dome, as less costly than engaging in a war of maneuver, which was essential to resolving Israel’s credibility issue regarding its willingness to act.
