Sun Zi: Adam, you speak of free markets and prosperity through trade. Yet nations wage economic wars, imposing tariffs and restrictions. If trade is truly beneficial, why do rulers seek to hinder it?
Adam Smith: Ah, my friend, it is often due to misplaced fears and short-term interests. Leaders believe protecting domestic industries will strengthen their economy, but they fail to see that such policies weaken all in the long run. Free trade allows nations to specialize and prosper together.
Sun Zi: You say they fail to see, yet they act with deliberate intent. Is this not a strategy of control rather than ignorance? A ruler does not block a road unless he fears what may come through it.
Adam Smith: Quite so. Some fear dependence on foreign powers, seeing trade as a weapon that might be turned against them. They view commerce not as mutual gain but as a battlefield. Yet war, even economic war, exhausts both sides. If a nation blocks trade, it injures itself as well.
Sun Zi: You speak wisely, yet you assume rulers seek the prosperity of all. In war, one does not always seek balance—one seeks dominance. If trade can make both sides rich, can it not also be used to make the enemy poor?
Adam Smith: A troubling thought, yet true. Some nations do use trade as a weapon—sanctions, embargoes, and tariffs to weaken rivals. But such tactics, like prolonged sieges, can be costly and unpredictable. Trade wars often lead to stagnation, not victory.
Sun Zi: Then would it not be wiser to master the art of interdependence? To make one’s enemy so reliant on trade that he dare not strike?
Adam Smith: That is, in essence, the invisible chain of commerce. If nations are bound together by trade, war becomes too costly for all. Yet rulers are not always rational. Some would cut off their own hand to wound another.
Sun Zi: Then, the greatest victory is to win without fighting. To weave trade so tightly that war is unthinkable. But tell me, if greed blinds rulers to this, how does one persuade them?
Adam Smith: By revealing that true wealth is not in hoarded gold, but in the free exchange of goods, ideas, and labor. Prosperity does not come from conquest, but from cooperation. Even the mightiest warrior needs supplies.
Sun Zi: Hmm… Perhaps the battlefield is not of swords and shields, but of wisdom and patience. A war fought not with armies, but with mutual need.
Adam Smith: Exactly. Trade, properly understood, is not a war—it is the end of war.
