But here's the twist: saying a country has "zero military" is rarely black and white. Some maintain no army but keep coast guards or police units trained for combat. Others outsource defense to allies. The reality is more nuanced than a simple yes-or-no answer. We’re far from it, actually. And once you peel back the layers, you start to see how fragile—and sometimes clever—the concept of peace can be when it isn't backed by tanks.
The Meaning of “No Military” – More Complicated Than It Seems
When people say a country has zero military, they usually mean no army, navy, or air force. But that doesn’t mean total defenselessness. Some nations have abolished their militaries by constitutional decree, like Costa Rica. Others simply don’t maintain one due to size, geography, or political alignment. The thing is, absence of an army doesn’t always translate to absence of armed personnel.
Take Iceland. No army. Never had one. Yet it hosts U.S. military forces under NATO agreements and maintains a small armed coast guard. Is that “zero military”? Technically, yes. Practically? Not quite. And that’s exactly where semantics start to blur. The issue remains: how do you define “military” when borders, threats, and alliances keep shifting?
Constitutional Disarmament – When Peace Becomes Law
Costa Rica is the gold standard here. In December 1948, President José Figueres Ferrer symbolically dismantled the country’s military barracks with a sledgehammer. Since then, Article 12 of the Costa Rican Constitution bans a standing army. Instead, public security falls to the Fuerza Pública, a civilian police force. The money once spent on defense—roughly 3% of GDP in the 1940s—now funds schools and hospitals. Today, Costa Rica spends seven times more on education than on defense.
But this didn’t happen in a vacuum. The 44-day civil war of 1948 killed over 2,000 people and sparked deep reforms. Figueres wasn’t just idealistic—he was strategic. By eliminating the military, he prevented future coups. And it worked. Costa Rica has remained stable, democratic, and peaceful for decades despite regional turbulence.
Civilian Policing as National Defense
In post-military countries, law enforcement often absorbs defense responsibilities. Panama, for example, dissolved its military in 1990 after the U.S. invasion that ousted Manuel Noriega. Now, the Servicio Nacional de Fronteras (SENAFRONT) handles border security with light arms and surveillance. They’re technically police, but they operate in military-like conditions—jungle patrols, anti-smuggling ops, joint exercises with U.S. Southern Command.
Likewise, Monaco has no army. Its 130-person Compagnie des Carabiniers du Prince performs ceremonial duties and guards the royal family. For real threats? It relies on France, per a 1918 treaty. So while Monaco spends zero on military hardware, it’s not defenseless. It’s just outsourced. And that’s a choice many microstates quietly make.
Small Nations, Big Alliances: The Power of Protection Pacts
Tiny countries often skip militaries because they can’t afford them—or don’t need to. Instead, they piggyback on powerful neighbors or alliances. This isn’t weakness. It’s pragmatism. Liechtenstein, nestled between Switzerland and Austria, abolished its army in 1868 after sending 80 soldiers to a war and having one go missing (he’d opened a pub in Italy). Since then, it’s relied on Switzerland for defense under an informal agreement.
Switzerland, by contrast, maintains a robust militia system. But Liechtenstein? It spends $0 on defense. Zero. Not a single franc. Still, it’s never been invaded. Why? Geography helps. So does neutrality. And that’s a pattern across Europe: small states avoiding armies because they’re surrounded by stability—or protected by treaties.
And yet—what happens when alliances falter? What if NATO weakened tomorrow? Iceland, with no army and only a 230-member coast guard, would be exposed. It’s a calculated risk. But for now, the math works. The cost of an army could exceed 20% of their defense budget. Without one, they invest in cybersecurity and disaster response. Smart? Absolutely. Foolproof? Honestly, it is unclear.
Iceland’s Unique Security Model
Iceland hasn’t had a standing army since 1869. It’s the only NATO member without one. But since 1951, it’s hosted U.S. troops at the Keflavík Air Base—off and on. The U.S. withdrew in 2006, then returned in 2016 amid Russian aerial activity in the North Atlantic. So Iceland’s “no military” status depends heavily on external actors.
Its coast guard, though small, has intercepted Russian reconnaissance planes and conducted search-and-rescue missions in Arctic waters. In 2021, they deployed drones for maritime surveillance. Not tanks, but tech. And that’s the shift: modern defense isn’t always about boots on the ground. It’s about sensors, satellites, and partnerships. To give a sense of scale: Iceland’s entire defense apparatus is smaller than a single U.S. Marine battalion.
Costa Rica vs. Panama: Two Paths, One Decision
Both countries scrapped their armies decades ago. But their reasons—and results—diverge sharply. Costa Rica abolished its military voluntarily, driven by democratic idealism. Panama did so under pressure, after the U.S. invasion dismantled Noriega’s repressive forces. The outcomes? Costa Rica ranks among the most peaceful nations in Latin America. Panama, while stable, still battles corruption and drug trafficking.
Costa Rica reinvested military savings into literacy programs. Today, it boasts a 98% literacy rate—higher than the U.S. Panama spends less on education (about 4% of GDP) and more on infrastructure. And that changes everything when you consider long-term resilience. One focused on human capital. The other on economic growth. Both avoided military rule. But only one made peace a national brand.
Which is better? I find the Costa Rican model more sustainable. Not because it’s perfect—crime rates have risen recently—but because it built institutions instead of quick fixes. Panama still struggles with police militarization. Costa Rica didn’t just disband an army. It redefined security.
Environmental Protection as National Strategy
Costa Rica spends nearly 5% of its budget on environmental programs—more than most countries spend on defense. Its national parks cover 25% of the territory. Eco-tourism generates over $1.7 billion annually. That’s not coincidence. It’s policy. By protecting nature, Costa Rica strengthens its economy and global image.
It’s a bit like using forests as a deterrent. Invading a country beloved for its green credentials? Politically messy. And that’s the point. Soft power can be as effective as hard power—if you play it right. Other nations watch. Some, like New Zealand, emulate this approach in foreign policy. Not with zero militaries, but with values-driven diplomacy.
Why Most Countries Can’t Follow Suit
Let’s be clear about this: abolishing a military only works under specific conditions. You need stability, trusted allies, and no active threats. Japan, for example, has a Self-Defense Force limited by its pacifist constitution—but in practice, it’s one of the world’s most advanced militaries. South Korea spends $46 billion on defense because it faces a nuclear-armed neighbor. Geography matters. History matters. Power matters.
Imagine Haiti trying to abolish its military. It already struggles with gang violence and political chaos. Without armed forces, who would respond to coups or invasions? The same goes for Ukraine—before 2014, it had a modest military. After Russia’s annexation of Crimea, it ramped up spending to $8.5 billion in 2023. Context is everything.
So why do we romanticize demilitarization? Because it feels noble. And it is. But it’s not universally applicable. The fantasy of a world without armies is beautiful. The reality is messier. Because peace isn’t the absence of weapons. It’s the presence of justice, equity, and trust.
Frequently Asked Questions
Can a Country Survive Without Any Armed Forces?
Yes—but only under the right conditions. Costa Rica, Iceland, and Liechtenstein survive without armies because they’re either neutral, allied with powerful nations, or face minimal threats. They replace traditional defense with diplomacy, policing, and deterrence through reputation. But in conflict-prone regions, going unarmed is extremely risky. Data is still lacking on long-term viability for larger or more vulnerable states.
Does the United Nations Provide Military Protection?
No. The UN doesn’t defend individual countries. It deploys peacekeepers to conflict zones—but only with host-nation consent and Security Council approval. Countries like Vanuatu or Samoa have no military and rely on regional partners (e.g., Australia or New Zealand) for emergencies. The UN won’t send troops if you get invaded. That’s on your allies—or lack thereof.
What Happens If a No-Military Country Gets Attacked?
It depends. Costa Rica faced incursions from Nicaraguan rebels in the 1980s. It responded with police and diplomatic pressure. Iceland relies on NATO’s collective defense clause (Article 5). If attacked, the U.S. and others would respond. But what if the attacker is a non-state actor? Or a cyberpower? That’s where gaps emerge. And that’s exactly why some experts argue for minimal defensive capabilities—even in pacifist states.
The Bottom Line
Several countries operate without traditional militaries—Costa Rica most famously. But “zero military” doesn’t mean “zero defense.” It means redefining security. Some use alliances. Others invest in soft power. A few, like Liechtenstein, get by on trust and treaties. The common thread? They’re small, stable, and shielded by geopolitics. For larger or threatened nations, this model doesn’t work. And that’s okay.
I am convinced that demilitarization isn’t a universal solution—but it’s a bold experiment worth studying. Because maybe, just maybe, the future of peace isn’t more weapons. It’s smarter choices. Suffice to say, Costa Rica’s gamble has paid off—for now. But history is long. And neutrality doesn’t guarantee safety. It just changes the odds.
