The Laws of War by Sun Tzu (literally translated as the world-famous Art of War) is an ancient (over 2500 years old!) Chinese treatise attributed to the general and strategist Sun Tzu, who lived in the late Chunqu period or early Zhangguo period.
Don't think that this text is just an echo of ancient times, interesting only to historians. Instead, it is still being studied today, for example, in the US army, in philosophy and political science departments of leading universities around the world.
Sun Tzu considered war a necessary evil. It is desirable to wage war quickly to avoid economic losses and gradually growing internal resistance (opposition of the nobility and discontent of the population), or to wage it on the enemy's territory to use his resources rather than our own.
He believed that strategy is not planning in the sense of working through a list of tasks, but rather that it requires a quick and adequate response to changing conditions. Thus, this treatise is not so much about military action as it is about organising the thinking and masses of people.
