Introduction
HENI OZI CUKIER: History has taught us many lessons, and we should pay attention to its signs because we might be heading towards World War III. One way to understand today’s events is to look for clues from the past, but cherry-picking historical events to forecast the future is a risky exercise that oftentimes only reinforces our biases. So I want to do something different. Instead of comparing historical examples with what is happening now, I will examine four major dimensions of life—the social, economic, political, and military dimensions. And I will analyze key trends within each one of those dimensions in three critical moments in history—before World War I, before World War II, and today.
The Social Dimension: Technology and Social Anxiety
So let’s begin with the social dimension. And there are many factors that shape societies, but I want to focus on how technological innovations have produced social anxieties and destabilized societies throughout history.
Before World War I, the Second Industrial Revolution was transforming life with electricity—cars, phones, mass production, and more. While many celebrated these advances, they also disrupted societies. For instance, machines replaced workers, and new farming techniques uprooted populations from the countryside. These led to insecurity and resentment. At the same time, traditional authorities, such as churches and monarchies, were questioned at that time, and new mass movements emerged, such as labor unions and nationalist leagues. People were afraid that progress was shaking the very foundation of societies.
Looking a little bit ahead, in the interwar years, before World War II, technology continued to affect life. The word robot was even coined in 1921, and it symbolizes fears of possibly machines substituting human jobs. At the same time, or a little bit later, the famous economist John Maynard Keynes warned us in 1930 of a new disease—namely, technological unemployment. During this period, we had communications revolutions that completely changed public discourse. So these media became powerful tools for propaganda, polarizing politics, and amplifying social fears. Traditionalists at that time worried that modern culture was simply eroding tradition, family, and religion.
Today, we are going through a technological revolution, driven by AI, digital media, and social platforms. The internet, smartphones, and social media have transformed the way we work, communicate, and even think. Psychologists debate how digital life is affecting children’s development, while concerns over privacy and surveillance and AI-driven job loss continue to grow. Technologies are spreading ideas across the globe, but also they are amplifying frustrations, fears, and divisions faster than ever before.
In short, technological progress brings incredible benefits, but they also breed insecurity, resentment, and uncertainty. Historically, such anxieties have made societies more unstable and vulnerable to extreme ideologies that fuel militarism and war.
The Economic Dimension: Two Perspectives on War and Prosperity
Now let’s talk about the economics. And I want to present two perspectives on the economics. The first one is related to a common idea that economic prosperity prevents wars. And the argument goes like this. I mean, it makes no sense for a nation to go to war and destroy its own wealth. They don’t want to go to war.
Before World War I, in 1914, Britain dominated global trade and finance. Germany was thriving industrially and expanding its exports. Both countries, they knew that there were no financial benefits that justify the enormous economic costs of going to war. However, World War I taught us a very important lesson. Economics may explain what can be done, but politics decides what will be done. Fear, ambition, miscalculation, all overrode by even the strongest economic success, showing us that simply war and peace are not decided by economic arguments alone. We have to take into consideration political, ideological, and strategic reasons.
Okay, so what is going on with the second perspective? And the common perspective says the following. People will assume that nations, they want to be wealth and powerful. It’s not that they don’t want that, they do, but they want something else. It’s better for them if they are wealthier or more powerful than their rivals, right? So what matters is the relative power. I want to be more powerful, I don’t want to be just powerful. I want to be more powerful than my enemy or my rival.
Let’s look at what happened at World War II. And in that moment, Germany and Japan, they did not see trade as mutually beneficial. Why? They were gaining less than their rivals, Britain, France, and the US, which made them vulnerable. What was their response? Searching for self-sufficiency and eventually war.
All right, so what is going on today? There are two main ideas that we see all over. The US-China economic interdependence will prevent war. Really, I just told you what happened in World War I, right? So economics alone do not determine geopolitical outcomes. We have to consider political, strategic, ideological, and many other factors. When we think of what is going on after, or what happened after, the COVID-19 pandemic and Russia’s invasion of Ukraine, at that moment, states realized that it’s too risky to be really dependent on your rival. So as nations reassess today their economic dependencies, they are all moving towards one thing, or actually two, self-sufficiency and economic nationalism, just like before World War II.
History reminds us that wars are not only caused by economic situations, but we have to take into consideration political factors and relative power.
The Political Dimension: Polarization and the Collapse of Order
All right, so let’s go to the political dimension. Here I want to talk about polarization, and polarization not only divides societies, but ultimately it might destroy the political order. Polarization comes in many forms. Divided media, political battles, legislative deadlocks, contested elections, and its worst form, political violence.
