The Israeli military and Shin Bet have conducted investigations into the failures that led to the Oct. 7 Hamas massacre, revealing that the catastrophe could have been prevented. The investigations are beginning to provide a full picture of the truth and will allow for identified shortcomings to be fixed. The Israeli military failed in its mission to protect Israeli civilians, and senior commanders have taken responsibility and retired, but no politicians, including Prime Minister Benjamin Netanyahu, have admitted any responsibility for the failure. The investigations have revealed misperceptions and preconceived ideas about the intentions of the attacker and their capabilities that led to the calamity. The author calls for an apolitical state commission of inquiry to thoroughly investigate the mistakes that led to the calamity.
