What A World Without Standing Armies Would Free Up In Resources And Trust

Let's be precise about the numbers, because precision matters when the stakes are this high.

According to the Stockholm International Peace Research Institute (SIPRI), global military expenditure in 2023 reached approximately $2.44 trillion. This represents about 2.3% of global GDP. The top five spenders — the United States, China, Russia, India, and Saudi Arabia — account for roughly 63% of the total.

The United States alone spends more on its military than the next ten countries combined. The Department of Defense budget for fiscal year 2024 was approximately $886 billion. When you add in nuclear weapons programs (Department of Energy), veterans' affairs, homeland security, intelligence agencies, and interest on debt from past military spending, the true national security expenditure exceeds $1.1 trillion.

These are not abstract line items. They represent physical realities:

- Over 750 US military bases in at least 80 countries - Approximately 13,000 aircraft in the US military fleet - 11 nuclear-powered aircraft carriers (no other country has more than 2) - An estimated 5,500 nuclear warheads in the US arsenal (Russia has approximately 6,200) - Over 1.3 million active-duty US military personnel

Globally, approximately 27 million people serve in armed forces worldwide. Add private military contractors, weapons manufacturers, intelligence operatives, and the entire supply chain that supports military operations, and the number of people whose livelihoods depend on the continuation of military spending is staggering.

This is the mechanism by which military spending becomes self-perpetuating. It's not just a budget line — it's an employment program, an industrial base, a network of political constituencies, and a cultural identity. President Eisenhower warned about the military-industrial complex in 1961. It has grown every year since.

The opportunity cost of military spending is the most consequential economic discussion that almost never happens. Here's what global military expenditure could fund, annually, if redirected:

End world hunger: The UN Food and Agriculture Organization and various estimates place the cost at $30-45 billion per year. That's roughly 1.5-2% of current global military spending.

Universal primary and secondary education: The UNESCO estimate for the global education funding gap is approximately $40 billion per year. Under 2% of military budgets.

Universal basic healthcare: The Lancet Global Health Commission estimates $274 billion per year for essential health services in low- and middle-income countries. About 11% of military spending.

Clean water and sanitation for everyone: WaterAid and the WHO estimate $28-35 billion per year. About 1.3%.

Address the climate financing gap: Developing nations estimate they need $1 trillion per year in climate financing. That's about 41% of current military spending. So even cutting military budgets by half globally would cover it.

Global infrastructure for renewable energy: The International Energy Agency estimates that reaching net-zero by 2050 requires approximately $4 trillion per year in clean energy investment. Military spending alone wouldn't cover it, but it would close a significant portion of the gap.

Tally it up: you could end hunger, educate every child, provide universal healthcare, deliver clean water to everyone, and make a massive down payment on solving climate change for roughly $400-420 billion per year. That's about 17% of what the world currently spends on military. We could do all of it and still have 83% of the military budget left over.

Let that sit for a moment.

The idea of a country without an army sounds utopian until you look at the list of countries that have actually done it. There are currently 22 sovereign states with no armed forces, plus several more with only minimal ceremonial or police forces.

Costa Rica is the most instructive case. In 1948, following a brief civil war, President Jose Figueres Ferrer abolished the military, redirecting the budget to education and healthcare. The decision was written into the constitution. Today, Costa Rica has: - A higher life expectancy than the United States - A literacy rate above 97% - Universal healthcare coverage - One of the highest happiness indexes in Latin America - A biodiversity conservation record that is the envy of much larger, richer nations

Costa Rica is not defenseless. It has a police force and border patrol. It benefits from regional security agreements. But it made a categorical decision: we will not maintain a standing army, and we will invest those resources in our people instead. The result, over seven decades, speaks for itself.

Iceland has never had a standing army in its modern history. It's a NATO member and hosted a US military base during the Cold War, but it has no armed forces of its own. It ranks consistently among the top countries in the Global Peace Index and the Human Development Index.

Panama dissolved its military in 1990, five years after the US invasion that removed Noriega. The constitution was amended to prohibit a standing army. Military spending was redirected to education, healthcare, and infrastructure. Panama's HDI has improved steadily since.

Japan is a more complex case. Article 9 of its postwar constitution renounces war and prohibits maintaining war potential. In practice, Japan has the Self-Defense Forces (SDF), which function as a de facto military. But the constitutional constraint has shaped Japanese foreign policy and spending priorities for 75 years, and Japan's per-capita military spending remains far below that of the United States.

Beyond the economic argument, there's a psychological one that goes to the heart of Law 1.

A standing army is, at its core, a materialized statement of distrust. It says: we expect that someone will try to harm us, and we are prepared to harm them in return. This is presented as realism, and in the current geopolitical context, it often is realistic. But it is also self-reinforcing. When every nation maintains the capacity for organized violence, every other nation must do the same. This is the security dilemma, and it is the most expensive trap in human history.

The security dilemma works like this: Country A builds up its military for defensive purposes. Country B sees the buildup and, unable to verify that it's purely defensive, builds up its own military in response. Country A sees Country B's buildup and increases its own spending. Each side is acting rationally from its own perspective. The result is an arms race that makes everyone poorer and no one safer.

Breaking this cycle requires what international relations scholars call "security communities" — groups of states that have developed such deep levels of mutual trust that the use of force between them has become inconceivable. The European Union, whatever its flaws, is the most successful security community in history. The idea of France and Germany going to war with each other — which happened three times between 1870 and 1945, killing millions — is now so absurd that it doesn't even register as a possibility.

How did that happen? Through economic integration, institutional interdependence, cultural exchange, and decades of deliberately building trust. It was not inevitable. It was a choice, sustained over generations, backed by resources and political will.

The question for the planet is whether this model can scale. If Western Europe — the bloodiest neighborhood in human history — can become a security community, what prevents the same process elsewhere? The answer is usually "but the threats are real" — and they are. But the threats in 1945 Europe were also real, and vastly more immediate than most current geopolitical tensions.

Nobody serious proposes that all nations disarm overnight. That would be destabilizing and dangerous. The question is whether there's a credible path from the current system to one with dramatically reduced military spending and eventually, for most nations, no standing armies.

A phased approach might look like:

Phase 1: Transparency and caps. Global agreement on military spending transparency (many nations currently obscure their true military budgets) and voluntary caps at a declining percentage of GDP. The Organization for Security and Co-operation in Europe (OSCE) already has mechanisms for military transparency that could be expanded.

Phase 2: Regional security communities. Building on the EU model, developing regional security architectures in which member states agree to mutual defense through shared institutions rather than individual military buildups. ASEAN, the African Union, and CARICOM are all potential foundations for this.

Phase 3: Force consolidation. Replacing national armies with robust international peacekeeping capacity under reformed UN command. This requires UN Security Council reform — specifically, eliminating the veto power that the five permanent members currently hold, which paralyzes collective security.

Phase 4: Demilitarization. As trust deepens and institutions prove reliable, individual nations begin reducing and eventually eliminating standing armies, following the Costa Rica model. Military budgets are constitutionally redirected to human development.

This is a multi-generational project. It won't happen by 2030 or 2050. But neither was the abolition of slavery a quick project, and yet it happened — because enough people decided that a practice the entire world had accepted as normal was, in fact, an abomination.

Here's where this connects to the premise of the entire book.

If every person said yes — yes, your children's lives are as valuable as mine, yes, I would rather build a school than a bomber, yes, I will trust you if you trust me — the military-industrial complex would collapse not from force but from irrelevance. Armies exist because we haven't collectively said yes. They are the physical infrastructure of our refusal to trust each other.

Every dollar spent on a missile is a dollar that says: I believe you might try to kill me, and I want to be ready to kill you first. That belief may be justified in the current system. But the current system is a choice. It was built by humans, and it can be rebuilt by humans.

The world without standing armies isn't a fantasy. It's a budget reallocation. The fantasy is believing that we can spend $2.4 trillion a year on preparing for war and still be surprised that we don't have peace.

1. Find out what percentage of your country's national budget goes to military spending versus education, healthcare, and infrastructure. Does the ratio reflect your values?

2. Calculate your personal contribution to military spending. If you pay taxes, you can estimate the portion that funds the military. How do you feel about that number? What would you rather it fund?

3. Research one country that has no standing army. What surprises you about how it functions?

4. If your country announced tomorrow that it would reduce military spending by 50% over ten years and redirect the funds to domestic priorities, what would your first reaction be? Fear? Relief? Excitement? Sit with whatever comes up and trace it to its source.
