IDF and Shin Bet reports exposed strategic blind spots in Israel's October 7 defense. The investigations revealed failures in Israel's security establishment and a lack of preparation for a mass attack by Hamas. Despite prior knowledge of the threat, the IDF left the border undefended, allowing Hamas to mobilize thousands of men and defeat the IDF on the ground. The reports highlight the need for a change in mindset and a more serious approach to security threats in order to prevent future disasters.
