Swords and guns are just tools, derived from the history of human evolution and civilization (things that are beneficial to oneself), and the person who controls swords and guns is the human subject, and the human subject is thought. There is no difference between a rule that only knows swords and guns and a machine that only knows how to reproduce and survive. What is the purpose of launching a war? There is no point in fighting a war and it only brings unnecessary sacrifices. Napoleon revealed a secret of human history to a great extent - that is, ignoring the power of ideology makes it difficult to achieve a country's independence and prosperity. In a certain historical period, the victory of force can change the status quo. However, human actions are controlled by thoughts. Controlling a person's thoughts is equivalent to controlling the person. Those who work hard on their minds use the method of enslaving their actions by taming their thoughts.
