Game Theory #22: Twilight of the Nation-State (Transcript)

Editor’s Notes: In this Game Theory lecture, Professor Jiang explores the evolving nature of global conflict and the “twilight of the nation-state.” This lecture argues that 21st-century warfare has shifted from battlefield maneuvers to a strategy of economic strangulation and infrastructure sabotage designed to turn civilian populations against their governments. By tracing the history of the social contract and the rise of nationalism, the episode provides a framework for understanding current geopolitical tensions, including the ongoing conflict between the U.S. and Iran. Finally, it addresses the potential for a surge in religious extremism and “eschatological” fanaticism as the only remaining psychological counter to this modern form of total societal pressure.

The First War of the 21st Century

PROFESSOR JIANG: There is a ceasefire now between Iran and the United States, but most analysts expect that this war will resume in a week, two weeks, a month, but it will resume because it is impossible for the United States and Iran to come to a mutually beneficial and satisfying arrangement. So today I want to look at how this war will evolve. And my argument to you today is that this U.S.-Iran war, it’s really the first war of the 21st century. And so I want to explain to you how warfare has evolved these past few hundred years.

How Warfare Has Evolved Over the Centuries

So the simplest way to fight a war is you would destroy a state’s capacity to fight by killing as many soldiers as possible, right? You would arrange to fight the enemy on a battlefield, whoever wins this battle would win the war. And that was how, traditionally, wars were fought for hundreds and hundreds of years.

But in the 21st century, something happened, which is that the state, a nation-state, developed the capacity to have a lot of people, millions of people. And so the state could always replenish its forces on the battlefield. And so now what you had to do was you had to destroy the state’s capacity to produce, to manufacture, okay? And this is really… And so the point is to kill as many civilians as possible before you want to kill as many soldiers as possible. But in the 20th century war, mainly World War II, you’re trying to kill as many civilians as possible.

But in the 21st century, it’s different, because we have nuclear weapons now, and there are too many people. So it is impossible for you to kill everyone. And if you use nuclear weapons, then others will use nuclear weapons on you, okay? So now, in the 21st century, our goal is to use the population against the state, to turn the civilians against the government by sowing as much discord and dissent as possible within society. And you do that through economic sabotage, economic strangulation, okay? So that’s the argument I will make to you today.

Eight Billion People and the Nation-State

The first thing I want to look at is, why is it that we have 8 billion people, 8 billion people are living on this planet? And for most of us, we think this is a tremendous achievement. But if you think about it, it’s not that nice, because there aren’t that many resources to share. There’s not that much space. In fact, if it were not for fertilizers, we would only be able to support 1 to 2 billion people. So how did we get to a stage where 8 billion people in this world, and most of us are not very happy with the state of affairs, okay?

And scientists will tell you, it’s because of the center of evolution. It’s because of this revolutionary technology and understanding that’s allowed us to progress. That’s not true, okay? The real reason is because of the nation-state, and the nation-state, it is a revolution in politics that came to us because of the French Revolution, all right?

Jean-Jacques Rousseau and the Social Contract

So the main architect of the French Revolution, his name is Jean-Jacques Rousseau. He was not French, he was actually Swiss. But he’s important because he developed a theory that underpinned the French Revolution called social contract theory. Before, we didn’t really think about what the individual’s relationship with the state was. Basically, you were born in a community, and you just did what tradition and custom and family asked you to do.

And Jean-Jacques Rousseau was the first to say, no, we are born free because God gave us freedom. So why do we choose to surrender our freedom in order to join a community, okay? And so his theory is that we join society to become more free. So by ourselves, we together, okay, all of us together, we create something called a common will. And think of this as democracy. Democracy is basically the idea that to make a decision, we just vote. And then whatever comes, whichever is the majority wins.

The General Will and the Categorical Imperative

So for example, we might debate whether we’re going to McDonald’s or Pizza Hut, okay? There’s three of us, if two of you say, let’s go to Pizza Hut, we go to Pizza Hut, and that’s just democracy. For Jean-Jacques Rousseau, this is not a good system, because we should strive to be higher than we are. We should strive for total freedom, and that’s the idea of the general will, okay? The common will is who we are. The general will is who we could be if we came together as a people, okay?

And the best way to understand the general will is through Kant’s theory of the categorical imperative, which is for him the highest moral law. So as human beings, what makes us truly human? What allows us to achieve our ideal state, our three principles, okay?

The first principle is the principle of universality. So imagine that all your actions will be reflected throughout the universe.
