A prominent feature of the 12-Day War was the cultural-social resilience demonstrated by Iranians in response to Israeli aggression against Iran. Throughout the conflict, a distinct manifestation of social cohesion and national unity emerged among Iranians, centered around the concepts of homeland and Islam. The central research question of this study is: What were the attitudes of Iranians toward the 12-Day War, and what role did cultural-social components play in fostering resilience against the Israeli assault? The article hypothesizes that the Iranian populace perceived the 12-Day War as an attack on Iran’s independence and territorial integrity and, due to shared cultural-religious elements and a strong spirit of patriotism, displayed a significant degree of cultural-social resilience. Research data were collected through library and internet-based methods and analyzed using a descriptive-analytical approach within the theoretical framework of Émile Durkheim. The findings indicate that Iranians considered their country the victor of the war and advocated for the preservation of missile programs to ensure national security. While demonstrating resilience in the face of conflict, they also acted to strengthen national cohesion within the digital sphere. In accordance with Durkheim’s theoretical perspectives, within Iranian society, components such as the conscience collective (collective consciousness), social similarities, religion and tradition, simple social structures, and holism have contributed to social cohesion.
