Throughout history, nations have used military investment to stimulate their economies, secure resources, and project power. One of the most notable examples is Nazi Germany, whose pre-World War II economic recovery relied heavily on massive state-sponsored rearmament. This policy, which aimed at rebuilding the military-industrial base, became unsustainable without the outbreak of war. In the modern world, powerful countries have adopted different approaches to sustaining their military-industrial complexes. The United States, as one of the most notable examples, has shifted away from direct internal military spending, instead promoting external support to foreign countries like Israel and Ukraine, encouraging them to purchase American-made arms and services. This economic model has significant effects on both global security and domestic industry. This article explores the similarities and differences between Nazi Germany’s direct military investment and the modern U.S. approach, analyzing how both economies have leveraged military spending to drive economic growth and global influence.
Unsustainability without War
Many historians argue that the Nazi war economy simply could not stand on its own without the outbreak of World War II. The heavy government deficits and fixed labor policies meant Germany lacked the normal market mechanisms to keep the economy balanced. A comprehensive analysis concludes that the regime’s financing methods were “unsustainable” and that by September 1939 the economy was in “dangerous disarray”. In other words, by the eve of war Germany was effectively poised on a fiscal cliff – high unemployment was artificially low, trade deficits were growing, and the state had little reserve.

This aligns with the infamous “guns or butter” trade-off: in peacetime democratic societies, such rearmament would be politically impossible to sustain. But Nazi ideology willingly sacrificed consumer welfare. As a history resource notes, the fall in unemployment was “mostly bad”, driven by deficit spending on infrastructure and arms rather than genuine productivity, and required conscription and exclusion of women and Jews from the workforce. In practice, the system “made war pretty much necessary by itself,” since economic growth could only continue through conquest. In sum, without war the Nazi economic buildup would likely have collapsed under its own financial weight. The regime’s leaders understood this: Hitler’s writings and speeches anticipated war as the means of sustaining the German economy’s recovery, and the Four-Year Plan explicitly linked domestic employment to military expansion.

US Military-Industrial Complex and Foreign Aid
In contrast, the modern United States supports its defense industry largely through global networks of allies and aid, rather than direct domestic rearmament alone. The US maintains a large standing military and high defense budgets (around 3–4% of GDP), but an ever-greater share of the benefit to industry comes from arms exports and foreign military assistance. The term “military–industrial complex” – coined by President Eisenhower – describes this nexus of Pentagon procurement, defense contractors, and policymakers. By Eisenhower’s warning, this system’s “economic influence” is “felt in every city, every statehouse, [and] every office of the federal government”. In practice, the US government underwrites arms sales and grants in ways that channel foreign aid dollars into American factories.

This foreign-aid-driven model has substantial economic effects at home. The defense industrial base – companies like Lockheed Martin, Boeing, Northrop Grumman, RTX (Raytheon Technologies), General Dynamics, and others – relies heavily on exports. In fact, as of 2019 the five largest US contractors alone accounted for most of the industry’s $100+ billion in annual foreign arms sales. According to industry data, the F-35 Joint Strike Fighter program (an international project led by Lockheed Martin) generates about $72 billion per year in US economic impact and supports roughly 290,000 jobs nationwide. Lockheed Martin itself employs some 121,000 people, and similar numbers work at other major defense firms or their large supply chains. For example, Raytheon (now RTX) builds the interceptor missiles for Israel’s Iron Dome in its Arizona factories. These factories, and the thousands of smaller suppliers across all 50 states, are kept busy by foreign orders.

A recent illustration: in May 2025 the Department of Defense announced potential deals totaling about $200 billion to Saudi Arabia and Qatar, involving American-made drones, missiles, and aircraft. Analysts noted that this is “huge potential business for major U.S. defense contractors like RTX, Lockheed Martin, Northrop Grumman and General Atomics”. Such deals translate into concrete jobs and economic growth in communities with weapons plants. Supporters often argue that foreign arms sales “strengthen our defense industrial base” and keep factories open – as Sen. Lindsey Graham put it, US allies are subsidized but they do “buy American equipment”, preserving US jobs.

Critics dispute that any large fraction of US jobs hinge on a single sales package (the entire US defense industry is still <0.5% of total US employment). Nevertheless, many states count defense as a key industry. President Trump’s 2017 visit to Saudi Arabia even featured a map showing thousands of American jobs tied to an $110 billion sale, underscoring how such arms deals are politically portrayed as local economic boons. Congressional supporters of FMF explicitly point to the potential for “lost U.S. jobs” (for example, in Maryland) if these subsidies were removed.

Strategic Logic: Direct vs. Outsourced Militarization
Comparing the two approaches highlights the divergent strategic rationales. Nazi Germany’s model was one of direct internal buildup: the state itself embarked on accelerated rearmament, expanding its own military-industrial base. This maximized control but also made the economy hostage to the regime’s military ambitions. In contrast, the US model is closer to outsourcing militarization through alliances. Instead of rebuilding an exhausted economy around its own armies, the US enables proxy and allied militaries to handle much of the fighting (and spending) with American support.
In theory, the US approach allows the US to project power globally without mobilizing a comparably large fraction of its own population. Allies and partners receive advanced weaponry, which contributes to regional deterrence. Each major arms sale or aid package is justified as strengthening collective security or countering rivals (e.g. selling F-35s to Taiwan is pitched as deterring China). In practice, it also keeps US manufacturers profitable. This “Indo-Pacific tilt” or Middle East strategy makes US allies into force multipliers for American defense, using US dollars.
Nazi strategy, however, was explicitly conquest-driven. Hitler aimed to use newly-rearmed armed forces to grab Lebensraum (living space) and resources, thereby sustaining the economy. That turned out to be disastrous: unchecked rearmament made war nearly inevitable and ultimately overwhelmed Germany’s capacity. The US strategy ostensibly hedges against outright war on American soil by keeping adversaries’ militaries at bay, but it has its own risks. Critics warn that flooding regions with US arms can spur arms races or draw the US into conflicts indirectly.
Implications: Conflict, Proliferation, Dependency
The consequences of the two models also differ. Nazi rearmament directly precipitated World War II and the devastation of Europe. Today’s US arms export model has not prevented war, but it spreads weaponry widely. In 2019 American companies accounted for the majority of global arms exports. US weapons are now ubiquitous from Ukraine to Yemen, Israel to the Indo-Pacific. This “proliferation” raises stability concerns: hostile actors often acquire advanced arms, and some US-supplied systems have been used controversially (e.g. US bombs in Yemen).
The U.S., while positioning itself as a global peacekeeper, arms allies, promotes regional conflicts, and directly benefits from global instability through its military-industrial complex. Ironically, the industries that profit from these arms sales, like Lockheed Martin and Raytheon, often advocate for more military intervention, perpetuating a cycle of violence under the guise of maintaining peace. As long as global peace remains tied to the interests of arms industries and military alliances, the rhetoric of peacekeeping rings hollow. True peace cannot be achieved while the economic models of powerful nations thrive on the continuation of war.
