War and Economics: How They Feed Each Other

In the winter of 1840, a British naval fleet sailed into the Pearl River Delta near Canton, China, carrying the most cynical cargo in the history of commerce. The ships were not there to trade silk or tea. They were there to force China to buy opium.

For decades, the British East India Company had been growing opium poppies in Bengal, processing the harvest into blocks of raw opium, and shipping it to China, where millions had become addicted. The trade was enormously profitable. It was also, by Chinese law, illegal. When the Qing Dynasty's commissioner, Lin Zexu, seized and destroyed over a thousand tons of British opium in Canton harbor in 1839, the British government did not apologize. It did not negotiate. It sent gunboats.

The First Opium War lasted three years. China, with its ancient civilization and vast population, was no match for British industrial firepower — steam-powered warships, rifled muskets, artillery that could blast through fortress walls. The Treaty of Nanking in 1842 forced China to cede Hong Kong, open five ports to British trade, and pay an indemnity of 21 million silver dollars. It said nothing about stopping the opium trade. That was the point.

This war was not about territory. It was not about religion. It was not about ideology. It was about money. A government went to war to protect its right to sell drugs to another country's people. And it won.

If you want to understand the relationship between war and economics, start here. Start with the purest case, stripped of all pretense: a war fought for profit, by a nation that wrapped its greed in the language of free trade.

This chapter is about that relationship — the deep, tangled, often invisible ways that economics causes wars, wars reshape economies, and the two feed each other in a cycle that has defined the last five centuries of human history.


Look Around You

The next time you hear about a war — any war — ask yourself a question that is almost never asked on the news: who profits? Not which country wins or loses. Who, specifically, makes money? Which companies sell the weapons? Which industries benefit from the destruction and the rebuilding? Which resources change hands? Wars are covered as political events. They are experienced as human tragedies. But they are also, always, economic events. Follow the money, and the war looks different.


Every War Has an Invoice

Let us begin with a statement that will sound cold but is precisely true: every war in modern history has had an economic dimension. Not every war is caused purely by economics — religion, nationalism, ethnic hatred, and the ambitions of individual leaders all play their part. But scratch beneath the surface of any major conflict, and you will find an economic motive, an economic cause, or an economic consequence that shaped everything.

This is not cynicism. It is observation. And it is important because if we understand the economic roots of war, we have at least a chance of addressing them before the killing starts.

"War is a racket. It always has been. It is possibly the oldest, easily the most profitable, surely the most vicious." — Major General Smedley Butler, US Marine Corps, 1935

Butler was not a pacifist or an academic. He was one of the most decorated soldiers in American history, a man who had fought in wars from the Philippines to China to Central America. And he came to a conclusion that haunted him: the wars he had fought had enriched a few and impoverished many. The patriotism was real. The sacrifice was real. But the profits went to people who never fired a shot.

Let us trace this pattern through history.

Colonial Wars: Markets, Resources, and the Flag

The era of European colonialism — roughly the sixteenth through the twentieth centuries — produced more wars than any period in history. And nearly every one of them was, at its core, about economics.

The Opium Wars were the most brazen example, but hardly the only one. Consider the Scramble for Africa.

In the 1880s, European powers carved up an entire continent among themselves. At the Berlin Conference of 1884-85, representatives of fourteen nations drew lines on a map of Africa, dividing territories they had never visited among peoples they had never met. No African was invited to the conference. The carving was done with rulers and pencils, cutting through ethnic groups, kingdoms, and ecosystems with a bureaucrat's indifference.

Why? Because Africa had what Europe wanted: rubber, ivory, gold, diamonds, copper, palm oil, and — most critically — labor. King Leopold II of Belgium claimed the entire Congo basin as his personal property. Under his rule, an estimated ten million Congolese died — from forced labor, starvation, disease, and outright murder — as they were worked to death extracting rubber for the bicycle and automobile tires that European consumers demanded. Leopold never visited the Congo. He managed it as a business, from his palace in Brussels.

Every border drawn in Africa, every colony established, every "protectorate" declared was an economic claim dressed in political language. The flag followed the trade, and the trade followed the profit.

  Result: The rich got richer.
  The colonized got poorer.
  And every expansion was backed by force.

India was the crown jewel of this system. As we will explore more fully in later chapters, the British did not simply rule India — they reorganized its entire economy to serve British needs. Indian cotton was shipped to Manchester, processed in British mills, and sold back to India as finished cloth. India's own textile industry — once the finest in the world — was systematically destroyed. When Indians protested, they were met with force. The economic extraction was enabled by military power, and the military power was funded by economic extraction.


What Actually Happened

The Opium Wars reshaped China's trajectory for over a century. The treaties that followed — the so-called "unequal treaties" — forced China to open its markets, cede territory, grant extraterritorial rights to foreigners, and accept opium imports. The Qing Dynasty, already weakened, never recovered. The humiliation contributed to the Taiping Rebellion (1850-1864), which killed an estimated 20 to 30 million people — more than World War I. The economic and political chaos continued through the fall of the dynasty in 1912, decades of civil war, Japanese invasion, and ultimately the Communist Revolution of 1949. When Chinese leaders today speak of "the century of humiliation," they are not being theatrical. The wound began with a war fought over drug profits.


World War I: When Industrial Rivals Collide

The First World War is taught as a story of alliances, assassinations, and nationalism. And those are real factors. But beneath them lies a deeper story: the collision of industrial economies competing for markets, colonies, and resources in a world that was running out of unclaimed territory.

By 1914, the major European powers had industrialized. Britain had led the way, but Germany had caught up and, in many sectors, surpassed it. German steel production exceeded Britain's. German chemical and electrical industries were the most advanced in the world. German shipping was challenging British dominance of the seas.

This was not just an economic statistic. It was a strategic threat. Britain's wealth and power depended on its empire and its control of global trade routes. A rising Germany, with its growing navy and its ambitions for "a place in the sun," threatened to upset the entire order.

France, meanwhile, had lost the industrial region of Alsace-Lorraine to Germany in 1871 and wanted it back — not for sentimental reasons, but because it contained some of Europe's richest iron ore and coal deposits. Without those resources, France's industrial capacity was permanently diminished.

Russia was industrializing rapidly, threatening to become so powerful that Germany's window of military advantage would close within a decade. Germany's military planners calculated that if they were going to fight Russia, better now than later — before Russian railways connected its vast territory and its enormous population could be mobilized.

The assassination of Archduke Franz Ferdinand in Sarajevo was the match. But the kindling had been stacked for decades — by industrial competition, colonial rivalry, and the desperate logic of nations that believed economic dominance required military supremacy.

"The lamps are going out all over Europe. We shall not see them lit again in our lifetime." — Sir Edward Grey, British Foreign Secretary, August 3, 1914

The war that followed killed approximately 17 million people and destroyed the economic order that had produced it. Empires collapsed — the Ottoman, Austro-Hungarian, Russian, and German. The financial center of the world shifted from London to New York. And the peace settlement — the Treaty of Versailles — planted the seeds for an even worse catastrophe.

Economic Collapse Breeds Extremism

The Treaty of Versailles imposed reparations on Germany so severe that John Maynard Keynes, who attended the peace conference as a British Treasury representative, resigned in protest and wrote a prophetic book: The Economic Consequences of the Peace.

Keynes argued that crushing Germany economically would not bring stability — it would breed resentment, extremism, and eventually another war. He was exactly right.

The reparations, combined with war debts, destabilized the German economy. As we discussed in Chapter 1, the hyperinflation of 1923 wiped out the savings of the German middle class. When the Great Depression hit in 1929, Germany was devastated. Unemployment soared to 30 percent. Banks failed. Businesses closed. Families that had rebuilt after the hyperinflation were ruined again.

Into this despair walked Adolf Hitler, offering simple answers to complex problems: blame the foreigners, blame the Jews, blame the treaty. The economic suffering was real. The anger was real. The scapegoating was politically useful. By 1933, Hitler was chancellor. By 1939, Europe was at war again.

This pattern — economic collapse leading to political extremism leading to conflict — is one of the most dangerous feedback loops in human history. And it did not end with World War II.

Think About It

Think about what happens in your own community when people lose their jobs and cannot feed their families. Do they become more tolerant or less? More patient with democratic processes or less? Now scale that up to an entire nation. Can you see why economists consider mass unemployment a security threat, not just an economic problem?


World War II: The Economics of Total War

The Second World War was history's most expensive conflict. The United States alone spent an estimated $4 trillion in today's dollars. Total global spending — military and civilian losses combined — may have exceeded $15 trillion. Approximately 70 to 85 million people died.

But the economics of World War II is not just a story of destruction. It is also a story of creation. The war effort drove technological innovation at a pace never seen before or since. Governments poured unlimited money into research, and the results transformed the world.

Radar was developed from laboratory curiosity to battlefield technology in just a few years, and after the war became the foundation of air traffic control and modern aviation.

Computing was born from the need to crack codes and calculate artillery trajectories. The British built Colossus to break German ciphers. The Americans built ENIAC to compute firing tables. These machines were the ancestors of every computer, smartphone, and server that exists today.

Jet engines were developed simultaneously by Britain and Germany during the war, and within two decades revolutionized commercial aviation, shrinking the world.

Nuclear energy — for better and worse — emerged from the Manhattan Project.

Antibiotics were mass-produced for the first time to treat battlefield infections, and penicillin became available to civilians after the war, saving millions of lives.

Synthetic rubber, nylon, and plastics were produced at industrial scale because Japan's conquest of Southeast Asia had cut off natural rubber supplies.

The cruel irony is that war, the most destructive human activity, has been one of the most powerful engines of technological progress. Governments that would never spend billions on pure research will spend without limit when national survival is at stake. And the technologies they produce, once the war ends, reshape civilian life in ways no one predicted.

"In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military-industrial complex." — President Dwight D. Eisenhower, Farewell Address, January 17, 1961

The Military-Industrial Complex

Eisenhower's warning is one of the most quoted — and least heeded — statements in modern political history. He was not a pacifist. He was a five-star general who had commanded the D-Day invasion. He understood war. And he was terrified by what he saw happening in peacetime.

During World War II, American industry had been mobilized for war production. Car factories made tanks. Appliance manufacturers made ammunition. Shipyards that had built freighters now built aircraft carriers. When the war ended, this industrial capacity did not simply disappear. It looked for new customers. And the biggest customer was still the government.

The Cold War provided the justification. The Soviet threat was real, but it was also enormously useful for defense contractors, military planners, and politicians whose districts depended on defense spending. A permanent war footing meant permanent defense budgets. By the 1960s, the US defense budget exceeded the GDP of most nations. Companies like Lockheed Martin, Boeing, Raytheon, and General Dynamics became some of the largest corporations in the world, and their primary customer was the US government.

The result was a self-reinforcing system: defense companies lobbied for larger budgets, funded political campaigns, and employed former military officers. Military leaders advocated for more weapons. Politicians supported defense spending because it created jobs in their districts. Journalists and think tanks, often funded by defense money, produced analysis that emphasized threats.

This does not mean every war was started by arms manufacturers. But it means that there is always a constituency that benefits from conflict — or at least from the threat of conflict. Peace is bad for business if your business is war.

India has its own version of this dynamic. The Indian military is the world's largest arms importer, spending tens of billions of dollars on weapons from Russia, France, Israel, and the United States. Every purchase creates dependencies, relationships, and interests that shape foreign policy. The push for defense self-reliance — "Make in India" in defense — is partly about reducing cost and partly about breaking these dependencies. We will explore this more in the next chapter.

Oil and the Middle East: Every War Has a Pipeline

If there is one resource that has shaped modern war more than any other, it is oil.

The story begins in World War I, when the British navy — the most powerful military force on earth — switched from coal to oil. Winston Churchill, then First Lord of the Admiralty, made the decision. Oil-powered ships were faster, more efficient, and easier to refuel. But Britain had coal in abundance and almost no oil. The decision made the British Empire dependent on oil from the Middle East — and that dependency has shaped global politics ever since.

After World War I, Britain and France carved up the Ottoman Empire's Middle Eastern territories. The borders they drew — Iraq, Syria, Jordan, Palestine — were not based on ethnic, tribal, or geographic logic. They were based on oil concessions and strategic interests. Iraq was assembled from three Ottoman provinces — Kurdish, Sunni, and Shia — that had little in common, because the British wanted the oil fields in the north (Kirkuk) and the south (Basra) under one administration they could control.

The pattern continued throughout the twentieth century. The 1953 CIA-backed coup in Iran overthrew a democratically elected government because it had nationalized the oil industry. The 1991 Gulf War was triggered by Iraq's invasion of Kuwait — a tiny, oil-rich emirate. The 2003 invasion of Iraq was justified on many grounds, but its critics pointed out that Iraq sat atop the world's third-largest proven oil reserves, and that the contracts for post-war reconstruction went largely to American companies.

The 1973 oil crisis — when Arab oil producers embargoed exports in retaliation for Western support of Israel — showed the world just how powerful the oil weapon could be. Prices quadrupled overnight. The American economy, the most powerful on earth, was brought to its knees by a handful of countries turning off a tap. Gas stations ran out of fuel. The stock market crashed. The entire global economy entered recession.

Oil is not just a commodity. It is a strategic weapon. And as long as the world depends on it, the politics of oil will be the politics of war.


What Actually Happened

The economics of the Ukraine conflict that began in 2022 revealed how deeply energy is woven into the fabric of war and peace. Russia, the world's second-largest oil exporter and largest natural gas exporter, invaded Ukraine and was met with unprecedented Western sanctions. But Europe had spent decades building dependence on Russian gas — Germany alone imported over 55 percent of its gas from Russia. Cutting off Russian energy meant economic pain for Europe: soaring energy prices, factory shutdowns, a cost-of-living crisis. Russia, in turn, earned record oil revenues in the first year of the war even as it was being sanctioned, because high oil prices more than compensated for reduced volumes. The war demonstrated a bitter lesson: you cannot sanction your energy supplier without sanctioning yourself. Europe's dependence on Russian gas was not just bad energy policy. It was a security failure. It gave Russia leverage that it used to devastating effect.


Internal Security: When Stomachs Are Empty, Governments Fall

Wars between nations capture headlines. But the most common form of conflict — the kind that affects far more people — is internal: civil wars, insurgencies, coups, and revolutions. And these are almost always rooted in economic failure.

The pattern is remarkably consistent across centuries and continents. When food becomes scarce, when unemployment soars, when prices for basic necessities rise beyond what ordinary people can afford, the social contract breaks down. People who cannot feed their families stop caring about political stability. They have nothing left to lose.

The French Revolution of 1789 was triggered, in its immediate sense, by bread prices. Harvests had failed, bread prices had doubled, and the urban poor were starving while the aristocracy feasted. The storming of the Bastille was an act of political rebellion, but it was hunger that put people on the streets.

The Arab Spring of 2011 followed the same pattern. Global food prices had spiked in 2010-11, driven by drought in Russia, speculation in commodity markets, and biofuel mandates that diverted grain into fuel production. In Tunisia, Egypt, Libya, Syria, and Yemen, populations that were already frustrated by corruption, unemployment, and authoritarian rule were pushed over the edge by the price of bread. The Tunisian revolution began when Mohamed Bouazizi, a street vendor who had been repeatedly harassed by authorities, set himself on fire. But behind his desperation was an economy that offered young people no jobs, no dignity, and no hope.

India understands this viscerally. As we noted in Chapter 1, no Indian government has survived an onion crisis. The connection between food prices and political stability is not abstract — it is the most immediate political reality in a country where hundreds of millions of people spend the majority of their income on food.

The Naxalite insurgency in India — one of the longest-running internal conflicts in the world — has its roots in economic deprivation. The tribal and marginalized communities in central and eastern India that have supported the Maoist movement are among the most marginalized in the country: landless, poorly educated, lacking access to basic services. The state failed them economically long before they turned to armed rebellion.

"A hungry man is not a free man." — Adlai Stevenson

This is why economists argue that economic policy is security policy. A country that cannot feed its people, that cannot provide basic employment, that allows inequality to grow unchecked, is not just failing economically. It is creating the conditions for its own destabilization.

The War-Economics Feedback Cycle

Let us now step back and see the full picture. War and economics do not simply cause each other in a straight line. They form a cycle — a feedback loop where each amplifies the other.

  THE CYCLE CONTINUES

  Breaking the cycle requires:
  - Economic interdependence (so war is too costly)
  - Strong international institutions
  - Addressing root causes: poverty, inequality,
    resource scarcity
  - Domestic economic stability: jobs, food, dignity

This cycle has played out repeatedly across history. The economic competition between European empires led to World War I, which led to the punitive peace of Versailles, which led to economic collapse in Germany, which led to World War II, which led to the Bretton Woods system and the Cold War, which led to arms races and proxy wars, which led to new economic arrangements, which led to new competitions.

Understanding this cycle does not make it inevitable. The European Union was founded precisely to break this cycle — to bind France and Germany so tightly together economically that war between them would become unthinkable. It has worked, remarkably well, for almost eighty years. Economic interdependence is not a guarantee of peace, but it raises the cost of war so high that rational leaders think twice.


Think About It

The European Union began as the European Coal and Steel Community in 1951 — an agreement to pool the production of the two materials most essential for making weapons. The logic was deliberate: if you share control of the raw materials of war, war becomes harder to wage. Can you think of other examples where economic integration has reduced the risk of conflict? Can you think of cases where economic interdependence was not enough to prevent war?


Wartime Innovation: Destruction as a Perverse Engine of Progress

We have already noted the technologies born from World War II. But the pattern extends far beyond that single conflict.

The internet — the technology you are most likely using to read these words, or one that shaped the world in which these words reach you — began as ARPANET, a US Department of Defense project designed to create a communications network that could survive a nuclear attack. The idea was that if any single node was destroyed, messages could be routed through the remaining nodes. This decentralized architecture, born from Cold War paranoia, became the foundation of the global internet.

GPS — the satellite navigation system in your phone — was built by the US military to guide missiles and coordinate troop movements. It was opened to civilian use in the 1980s and is now essential to everything from ride-hailing apps to precision agriculture.

The jet engine, as we mentioned, emerged from wartime research. So did microwave ovens (from radar technology), duct tape (originally called "duck tape," used to seal ammunition cases), and even the EpiPen (derived from a military autoinjector for nerve agent antidotes).

This creates a troubling moral question. If war drives innovation, should we be grateful for war? The answer is clearly no — because the innovation could have happened without the destruction. The problem is not that war creates technology. The problem is that governments, left to peacetime incentives, tend to underinvest in basic research. War removes the budget constraint. When survival is at stake, money is no object. The lesson is not that we need war for progress. The lesson is that we need the same willingness to invest in peacetime that we display in wartime.

The Gulf Wars and the New World Order

The 1990 Iraqi invasion of Kuwait is often presented as a story of a dictator's aggression. And Saddam Hussein was indeed a dictator who invaded a sovereign nation. But the economic backdrop is essential.

Iraq had fought an eight-year war with Iran (1980-1988) and was deeply in debt — owing an estimated $80 billion. Much of that debt was owed to Kuwait and Saudi Arabia, who had lent generously during the war because they feared Iran more than Iraq. When the war ended, Iraq expected its debts to be forgiven. Kuwait refused. Worse, Kuwait was producing oil above its OPEC quota, driving down the global oil price at a time when Iraq desperately needed high oil revenues to service its debts.

Saddam's invasion was an act of economic desperation as much as territorial ambition. Kuwait was small, rich, and sitting on some of the largest oil reserves in the world. Seizing it would eliminate Iraq's debt, increase its oil reserves dramatically, and give it enormous leverage over global oil markets.

The US-led response — Operation Desert Storm — was justified in terms of international law and the sovereignty of nations. But the speed and scale of the response was also driven by a very specific economic interest: the world's oil supply. Had Kuwait produced turnips instead of oil, it is hard to imagine the same reaction.

The Economics of the Current Moment

The conflicts of the 2020s — the war in Ukraine, tensions over Taiwan, instability in the Sahel — all have deep economic roots.

The Ukraine conflict is inseparable from the economics of energy. Russia's leverage over Europe came from its gas pipelines. Europe's inability to respond decisively in the early stages came from its energy dependence. The sanctions regime — the most extensive in modern history — was designed to cripple Russia's war-making capacity by targeting its economy. Whether it has succeeded is debated, but the principle is clear: in the modern world, economic warfare and military warfare are intertwined.

The tension over Taiwan is, at its core, partly about semiconductors. Taiwan produces over 90 percent of the world's most advanced chips through TSMC. These chips are essential to everything from military systems to smartphones. A Chinese takeover of Taiwan would give Beijing control over the global semiconductor supply — an economic weapon of unprecedented power. The US CHIPS Act, which dedicates over $50 billion to building semiconductor manufacturing capacity in America, is as much a national security measure as an economic one.

In the Sahel region of Africa — Mali, Burkina Faso, Niger — military coups have overturned democracies in rapid succession. The underlying cause in each case was the same: governments that failed to provide economic security lost their legitimacy. Poverty, unemployment, food insecurity, and the perception that democratic institutions served only a corrupt elite created fertile ground for military leaders who promised order and national dignity.


Think About It

India spends approximately 2 to 3 percent of its GDP on defense. This amounts to roughly Rs 6 lakh crore in recent budgets — making India one of the top five military spenders in the world. Is this too much, too little, or about right? What are we not spending on because we are spending on defense? And what would happen if we spent less? These are not questions with easy answers. But they are questions every citizen should think about.


The Price of Peace

If war is so destructive and so expensive, why does it keep happening? Part of the answer lies in the feedback cycle we described. Part of it lies in the military-industrial interests that benefit from conflict. Part of it lies in the ancient human tendency to see the world in terms of us and them.

But part of the answer is also this: peace is expensive too. Maintaining peace requires investment — in diplomacy, in international institutions, in economic development that addresses the root causes of conflict. Preventing war means spending money on schools, hospitals, roads, and jobs in places that are volatile. It means funding the United Nations, the World Food Programme, and peacekeeping operations. It means foreign aid that is not charity but investment in global stability.

The world spends roughly $2.2 trillion per year on military expenditure. It spends roughly $200 billion on foreign aid. For every dollar spent trying to prevent conflict, ten dollars are spent preparing for it.

"If you want peace, prepare for peace — not just for war." — Adapted from the Latin proverb "Si vis pacem, para bellum"

There is an alternative reading of the ancient proverb. "If you want peace, prepare for war" has been the dominant philosophy for millennia. But perhaps the evidence suggests a modification: if you want peace, prepare for both — a military that deters aggression, and an economy that removes the conditions in which aggression breeds.

The Bigger Picture

We began with British warships in the Pearl River Delta, forcing a nation of four hundred million to buy opium at gunpoint. We have traveled through the trenches of World War I, the rubble of World War II, the oil fields of the Middle East, the corridors of the Pentagon, and the streets of Tunis and Kyiv.

What have we learned?

First, that war and economics are inseparable. Every war has economic causes, economic motives, or economic consequences — usually all three. To understand any conflict, you must understand the money behind it. "Follow the money" is not just advice for detective novels. It is advice for understanding history.

Second, that economic failure is the most reliable predictor of conflict. Hungry people revolt. Unemployed young men are recruited by extremists. Nations that feel cheated by the economic order seek to overturn it by force. The most effective defense policy any nation can have is an economy that provides jobs, food, and dignity to its people.

Third, that war creates as well as destroys — but the creation is accidental, while the destruction is certain. The technologies born of war could have been born of peace, if we had the wisdom and the will to invest in them. The lesson of wartime innovation is not that war is useful. It is that we are capable of far more than we normally attempt.

Fourth, that the military-industrial complex is real, and its interests do not always align with the interests of the people it claims to protect. Eisenhower's warning was not the raving of a peacenik. It was the considered judgment of a man who had seen war up close and knew its true costs.

And finally, that the cycle can be broken. The European Union broke it for Europe. Economic interdependence, strong institutions, and democratic accountability can raise the cost of war so high that it becomes unthinkable. This is not idealism. It is engineering — the engineering of incentives, institutions, and relationships that make peace more profitable than war.

The question is whether we have the wisdom to apply this engineering everywhere, or whether we will keep learning the same lesson the hard way — in blood, in rubble, and in the quiet, devastating arithmetic of lives unlived.

"The central problem of our age is how to act decisively in the absence of certainty." — Bertrand Russell

The next time you hear about a conflict — anywhere in the world — do not just listen to the political narrative. Ask the economic questions. Who profits? Who pays? What resources are at stake? What economic failures created the conditions? And what economic arrangements might prevent it from happening again?

Those are the questions that might, someday, help us break the cycle.
