The War Economy

Military Keynesianism: War as Economic Policy

The most inconvenient truth in American economics is this: the New Deal did not end the Great Depression. World War II did.

In 1939, after six years of FDR's ambitious domestic programs — the WPA, CCC, Social Security, Tennessee Valley Authority — unemployment still stood at 17.2%. The economy had recovered from its 1933 nadir but remained deeply depressed. It was not until the massive mobilization for World War II that the American economy truly roared back to life.

Between 1940 and 1944, real GDP roughly doubled. Unemployment fell from 14.6% to 1.2% — effectively zero. Sixteen million Americans served in the armed forces; millions more built ships, planes, tanks, and ammunition in factories running 24 hours a day. Women entered the workforce en masse. The government spent money on an unprecedented scale — military spending reached 41.9% of GDP in 1944, a figure that would be considered insane in any other context.

The lesson was not lost on policymakers. If government spending on the military could end the worst economic crisis in American history, then perhaps permanent military spending could prevent the next one. This insight — that war spending is the most politically palatable form of Keynesian stimulus — became the foundation of the American economic order for the next 80 years.

NSC-68: The Document That Made War Permanent

In 1950, Paul Nitze authored NSC-68, a classified National Security Council document that would become the blueprint for American military spending for the next 75 years. The document argued that the Soviet threat required a permanent, massive military establishment — not just in wartime, but in peacetime. It explicitly invoked Keynesian economics, arguing that military spending would stimulate the economy rather than drain it.

“The United States could achieve a substantial absolute increase in output and could increase the allocation of resources to a build-up of the economic and military strength... One of the most significant lessons of our World War II experience was that the American economy, when it operates at a level approaching full efficiency, can provide enormous resources for purposes other than civilian consumption while simultaneously providing a high standard of living.”

Translation: We can spend massively on the military and still grow the economy. War spending is not a sacrifice — it's stimulus. This argument won the day. Truman tripled the defense budget. It never came back down. Before Korea, defense spending was about 5% of GDP. After Korea, it never fell below 3%, even in the most peaceful years. The permanent war economy was born.

Cold War R&D: The Military Gave Us the Modern World

The strongest argument for military spending as economic policy is the extraordinary list of technologies that originated in military R&D and transformed civilian life. The digital revolution — the internet, GPS, microchips, touchscreens, voice recognition — was substantially funded by the Department of Defense and its research arm, DARPA.

This is not an accident. During the Cold War, the Pentagon was the largest single funder of R&D in the world. Military contracts sustained entire industries. The semiconductor industry was literally created by military demand — the Pentagon was buying 100% of American chip production in the early 1960s for missile guidance systems. Without those purchases, Silicon Valley might not exist.

The Counter-Argument: Could We Have Done It Without War?

The military-funded-everything narrative is powerful, but it raises an uncomfortable question: did we need to route R&D through the Pentagon? Could civilian agencies have produced the same innovations at lower cost and without the weapons attached?

Economist Seymour Melman argued in The Permanent War Economy (1974) that military spending actuallyharms the civilian economy by diverting the best engineers, scientists, and capital away from productive uses. While the US was building ICBMs, Japan and Germany were building cars and consumer electronics. By the 1980s, those countries had higher-quality manufacturing and faster productivity growth — precisely because their engineers were building things people could use, not weapons they hoped never to fire.

The internet could have been developed by a civilian research agency. GPS could have been a civilian navigation project. The fact that these technologies came through the military says more about American political culture — where military spending is easy to approve and civilian R&D is not — than about any inherent military advantage in innovation.

The Revolving Door: Personnel as Policy

The war economy is sustained not just by contracts and spending, but by people. The revolving door between the Pentagon and the defense industry is the mechanism that ensures military spending never decreases, weapons programs are never cancelled, and the definition of “threat” always expands to justify larger budgets.

The pattern is systematic. A general or admiral retires from the Pentagon, waits the legally required one year (sometimes less with a waiver), and joins a defense contractor at 5–10× their government salary. They bring with them relationships, insider knowledge, and the ability to shape future procurement. The contractor gets access. The official gets wealth. The taxpayer gets the bill.

This isn't corruption in the traditional sense — there are no suitcases of cash. It's structural corruption. The system is designed so that the people who decide how to spend $886 billion per year have a personal financial interest in spending more, not less. It's a feature, not a bug.

Company Towns: When the Base IS the Economy

The political power of military spending is concentrated in specific communities where the military base or defense plant is the dominant employer. These towns are, functionally, company towns — except the company is the Department of Defense, and the product is war.

When a senator from Texas votes against closing a military base, they're not making a strategic assessment of national defense needs. They're protecting the 45,000 military and 9,000 civilian jobs at Fort Cavazos that account for 73% of Killeen's economy. When a representative from Connecticut defends submarine procurement, they're protecting the 10,000 General Dynamics jobs in Groton that account for 52% of the local economy.

BRAC: The Impossible Politics of Cutting

The Base Realignment and Closure (BRAC) process was invented specifically because Congress could not bring itself to close military bases on its own. The process — where an independent commission recommends closures and Congress must vote on the entire package, no cherry-picking — was the only way to overcome the political impossibility of each member protecting their own bases.

Even so, BRAC rounds have been extraordinarily painful. The 2005 BRAC round was the last one completed. Congress has refused to authorize a new round for 20 years, despite the Pentagon repeatedly requesting one. The reason is simple: every base closure means lost jobs, and no member of Congress wants to explain to constituents why they voted to eliminate the town's largest employer.

The result is that the US maintains bases it doesn't need, in locations chosen for political rather than strategic reasons, at a cost of billions per year. The war economy doesn't just grow — it calcifies. Once military spending is embedded in a community, removing it becomes politically impossible.

The Scale of It

To understand the war economy, you have to understand the scale. The United States spends more on its military than the next 10 countries combined. This is not an exaggeration — it is arithmetic.

The Trap

The war economy is a trap because it works just well enough to be politically unassailable. Military spending does create jobs. It does fund R&D. It does sustain communities. These are real benefits with real beneficiaries who will fight to protect them.

But military spending is also the least efficient form of government stimulus. According to the Political Economy Research Institute at UMass Amherst, $1 billion in military spending creates approximately 11,200 jobs. The same $1 billion spent on education creates 26,700 jobs. Healthcare: 17,200 jobs. Clean energy: 16,800 jobs. Infrastructure: 17,000 jobs.

For every dollar spent on war, we get fewer jobs, less economic growth, and less public benefit than if that dollar were spent on almost anything else. But military spending has one advantage that no other form of government spending possesses: bipartisan support. Try getting Congress to spend $886 billion on education. Try getting Congress to spend $886 billion on healthcare. Try getting Congress to spend $886 billion on infrastructure. You can't. But military spending? Rubber-stamped every year, often with increases beyond what the Pentagon even requests.

This is the trap. The United States has built an economy that depends on military spending not because military spending is the best use of resources, but because it is the only form of large-scale government investment that American political culture permits. We don't have an industrial policy — we have a defense budget. We don't have a technology strategy — we have DARPA. We don't have a jobs program — we have military bases in every state.

Eisenhower saw it coming. In his 1961 farewell address, he warned of the “military-industrial complex” and its “unwarranted influence.” He was right. But he was also part of the system that created it. The highway system he championed was justified as the National Defense Highway System. The science education boom he oversaw after Sputnik was framed as a national security imperative. Even Eisenhower, who saw the danger, could only get things done by routing them through the military.

“Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children.”

The Bottom Line

The American economy is addicted to war spending. The addiction started with the genuine emergency of World War II, was institutionalized by the Cold War, and has become self-perpetuating in the War on Terror era. Every community with a military base, every worker at a defense plant, every engineer at a contractor, every member of Congress with military facilities in their district has a personal interest in the continuation of high military spending — regardless of whether there is a genuine threat to justify it.

The war economy doesn't need enemies. It creates them. When the Soviet Union collapsed, the military budget barely dipped before 9/11 provided a new justification. When the War on Terror wound down, the “pivot to Asia” and “great power competition” with China emerged. Now Iran. There will always be a next threat, because the economy requires one.

The question is not whether military spending benefits some Americans — it clearly does. The question is whether there is a better way to create jobs, fund R&D, and sustain communities that doesn't require building weapons and finding enemies to use them on. The answer is obviously yes. The political will to do it is obviously absent. And so the war economy rolls on.
