Any reasonable person could see that disaster was imminent and sound the alarm. The defense minister did it and was fired (and then reinstated with street protests), and the chief of staff and the heads of security organizations did it, but the prime minister didn't want to hear.
One of Israel’s goals in this war is to avoid being dragged into a multi-front war, which could split Israel’s focus and attention and weaken its operation against Gaza.
After two days of being held by Hamas, villages in Israeli control but search for terrorists and victims continues, with the IDF "on the offensive." More than 700 Israeli residents dead in worst terrorist attack in Israeli history.
Like in the Yom Kippur War, the entire political and security leadership is accountable for the failure. The dire result is that even hours after the start of the attack, which erupted at 6:30 AM, there were still besieged towns, terrorists barricading themselves in houses, and a significant number of civilians and soldiers who had been kidnapped and taken into Gaza.
The political echelon should instruct the IDF to immediately create a 300-meter wide security zone on the Gazan side running the length of the border and declare that any Palestinian that enters this zone is placing his life at risk.
