This is very true. The Japanese saw honor in dying while attacking, especially if attacking against insurmountable odds. This ensured that their best men were dead. They would not fall back to regroup, restructure their setup and attack again. Once the attack began, it was final until everybody was dead. This was an untold advantage for the United States.
