This study analyzes the Gaza crisis through Michael Brecher's Crisis Management Model, focusing on its evolution across four main stages: onset, escalation, de-escalation, and impact. The central question explores the factors influencing the development of the crisis. Using the process-tracing method, the study aims to identify and explain these dynamics. Findings show that in the onset stage, Israeli policies—such as illegal settlements, economic blockade, and disregard for international resolutions—created conditions for growing tension. The escalation phase began with Hamas’s large-scale attack on October 7 and was met with a strong Israeli military response, expanding to regional clashes with Hezbollah and Iran. The de-escalation stage involved diplomatic efforts and ceasefires among key actors, including agreements between Hezbollah and Israel, and between Hamas and Israel, which helped contain the crisis. Finally, the impact stage reflects strategic shifts in the region, weakening of the resistance axis, failure of Israeli deterrence, and possible redefinition of security policies by major players, including the Islamic Republic of Iran. Data were collected from written sources such as books, articles, documents, and online materials.
