TRANSCRIPT:

Understanding Realism vs. Liberalism

JOHN ANDERSON: Well, John, thank you so very much for joining us. We really appreciate your time. You’re coming from Chicago in the afternoon. I’m coming from my farm in Northwest New South Wales early in the morning, and it’s very kind of you to give us your time. Can you kick us off? Your approach to international relations might be called realism as opposed to liberalism. Can you tell us what that means and how you go about viewing this very troubled world we live in, which we’re going to talk about quite a bit?

PROFESSOR JOHN MEARSHEIMER: Sure. Realists believe that power is the currency in international politics, and that states care above all else about the balance of power. The reason states care about the balance of power is because they operate in a world where there’s no higher authority that can come to their rescue if they get in trouble. And at the same time, they can never be sure that a really powerful state in that system won’t come after them, won’t attack them.

If that happens, of course, there’s no one that they can turn to. So what that mandates is that states be as powerful as possible relative to the other states in the system. This is what drives the concern about the balance of power.

What drives many people in the West crazy about realism is the fact that it says that all states behave that way, democracies as well as authoritarian states as well as communist states. All states, in effect, are locked in an iron cage and behave roughly the same way.

As you can imagine, most people in the West who are quite liberal want to believe that there’s a difference between liberal democracies on one hand and authoritarian states on the other. But that’s not the realist view. That is the liberal view.

Let me just lay out very quickly the most prominent liberal theory because I think it’ll be quite clear how it contrasts with realism. That theory is democratic peace theory. It argues that in a world where you have lots of democracies, those democracies will not fight each other. In other words, those democracies, when they think about each other, won’t worry about the balance of power the way realists say they will. But because they’re liberal democracies, they will live in peace. A realist would not accept that argument. But in the liberal West, that’s obviously going to be an argument or a theory that is very attractive.

So I think in capsule form, that summarizes the difference between realism and liberalism.

Power, Morality, and Strategic Interests

JOHN ANDERSON: For me, John, I understand what you’re saying. I get it clearly as two different models, but it immediately raises the question then, does that mean that power is always or might is always right, that power is always about, if you like, authority over others, or does it leave room for higher ideals versus lower ideals? Another way of putting it, is there such a thing as a good nationalism, or is it always competitive and inclined to bear its fangs?

PROFESSOR JOHN MEARSHEIMER: Well, I like to argue that there are instances where doing the right thing, the moral thing, the correct thing from an ethical point of view is consistent with what’s the correct thing to do from a realist point of view.

In other words, if you go to war against Adolf Hitler, that’s the morally correct foreign policy as well as the strategically correct foreign policy. And here we’re talking about the United States during World War II. So the arrows are lined up in a very important way.

But you sometimes run into circumstances where doing the strategically correct or the realist way of acting is in conflict with what is correct from a moral point of view. And the realist argument is that in those cases, you will act according to the dictates of realism.

Going back to World War II, the United States, as you know very well, formed a very close alliance with Joe Stalin and the Soviet Union and worked closely with the Soviet Union to defeat Nazi Germany. Having a close alliance with the Soviet Union is not the ethically correct thing to do. But from a strategic point of view, it made eminently good sense. So we did it. And we, in the process, dressed up Joseph Stalin as a burgeoning democrat, and we were hardly ever critical about the Soviet Union because of its political system. We did all of this because the Soviets were our allies. We needed them to defeat Nazi Germany.

So a lot depends on whether ethical considerations and strategic considerations are in sync or out of sync.

Post-War American Leadership

JOHN ANDERSON: Let’s think that one through a little bit. I hear what you’re saying, and it makes perfect sense. But then I sometimes say to people that at its best, America after the Second World War as a leader of the allies, the victorious side if you like, in many ways behaved, I would have thought you could say very wisely and ominously. You might simply say realistically in relation to both the rebuilding of Europe, think the Marshall Plan, think putting the place back together, strings attached to the thirteen billion, which was a lot of money in those days. These days, it seems to be pocket change, but it was a huge amount of money.
