Defending oneself is essential to the human condition. While soft power can achieve peace, it is only effective with the threat of violence. Learning self-defense deters attackers by creating the perception that potential victims will not be weak. It also provides confidence, empowerment, and physical fitness. If everyone knew self-defense, it could make the world a better place by requiring attackers to better themselves through education and jobs, leading to a more peaceful society where citizens are responsible.
