The 10 Safest Countries in a Third World War

This question gets asked in waves. Tensions rise somewhere, the headlines get louder, and people start searching for where they would go.

I want to answer it seriously, because it deserves a serious answer. The serious version is less dramatic than the bunker-and-canned-goods version the internet usually supplies, and a good deal more useful. Judging where this industry's advice is worth listening to is its own exercise — I wrote up one of its larger conferences as an attendee.

I am not a geopolitical analyst. What I do professionally is help families build second residencies and citizenships, which means I have this conversation constantly with people who are genuinely thinking about it. The useful framing is not where do I hide. It is what would make a country resilient, and whether you have the legal right to be there before you need it.

Last reviewed 1 August 2026. The five criteria below are structural and move slowly. The geopolitical backdrop and the processing timelines do not, so I have dated those where they appear. If you are reading this a long way from that date, take the framework and check the timings.

The five things being scored

A ranking is only as good as what it measures, and most versions of this list measure vibes. Here is what I think genuinely determines whether a country holds together, and why each one earns its place.

Political neutrality. Not stated neutrality — credible neutrality, with a history behind it and no treaty obligation that drags the country in automatically.

Geographic isolation. Distance and water still work. An island or a country at the end of a long supply line is harder to reach, harder to pressure, and less useful as anyone's forward position.

Food and energy self-sufficiency. The one people skip, and the one that decides how a country's third year goes rather than its first. A nation that imports most of its calories or its fuel is exposed long before anything reaches it militarily.

Credible defence or deterrence. This is not the same as military size. It is whether attacking the place is more expensive than leaving it alone.

Social stability. Institutions that function under stress, and a population that does not fracture when rationing starts. This is the criterion that quietly disqualifies several countries that score well on the other four.

Ten countries score well against those five, one sits just outside, and a handful of very small states — including a couple in this region — score considerably better than their size suggests.

Before the list, though, the sentence that matters more than any ranking on this page: safety you cannot legally access is not safety. Residency or citizenship has to exist before a crisis, not during one, and every route to acquiring one is measured in years rather than weeks. Borders close to the people who need them most, at exactly the moment they need them. That is why the useful version of this question is not "where is safest" but "where do I already have the right to be" — and why the last section decides more outcomes than the list does.

The ten that score best

Ten countries, ranked. The ranking is my own judgement against the five criteria above. It is a reasoned ordering, not a computed index, and I would not defend the difference between seventh and eighth very hard. What I would defend is the shape of the list — particularly that the top three are not the top three for the same reasons.

1. New Zealand — the perennial answer: extremely isolated, food-exporting, largely renewable electricity, stable institutions. It is also the reason "billionaire bunker in New Zealand" became a genre. The catch is that immigration is not easy. It is also not neutral in the Swiss sense — it sits inside Western intelligence-sharing arrangements — but it is a long way from anywhere that matters militarily.

2. Switzerland — neutral for centuries, mountainous, famously prepared. It maintains civil-defence infrastructure at a scale no other developed country matches, and food and fuel reserve requirements written into law. This is the only country on the list where preparedness is a legal obligation rather than a national temperament.

3. Iceland — remote North Atlantic, tiny population, essentially all electricity and heating from geothermal and hydro. Genuinely energy-independent in a way almost nowhere else is. Two weak points, and they are real: it imports most of its food, and it is a founding NATO member with no standing army of its own. Isolated, but not neutral, and not self-defending.

4. Uruguay — the strongest all-round answer in South America: stable, democratic, agriculturally self-sufficient, far from any plausible flashpoint, non-aligned, and unusually open to foreign residents. It is the one on this list that is easiest to act on.

5. Chile — the Atacama, the Andes and the Pacific make it one of the most naturally defended countries on earth. It has a diversified economy and serious agriculture, and it is non-aligned. The weak point is political volatility rather than geography.

6. Fiji and the Pacific island states — extreme isolation and no strategic value to anyone. The dependence on imported fuel and goods is real, and the Pacific is markedly more contested than it was a decade ago.

7. Ireland — militarily neutral, an island, agriculturally productive, in the EU without being in NATO; energy import dependence is the weakness.

8. Costa Rica — abolished its military in 1948, politically stable, high renewable generation, agriculturally rich. No army is a genuine deterrence gap; it has worked for seventy-five years.

9. Australia — resource-rich, food-secure and enormous, with the caveat that it sits firmly inside Western alliance structures. That cuts against neutrality and makes it a participant rather than a bystander.

10. Canada — the same profile as Australia, and for the same reasons: abundant food, energy and space. That is offset by NATO membership, and by a border with the country most likely to be at the centre of any global conflict.

Just outside: Japan — advanced, orderly and unusually resilient to disaster, but resource-import-dependent and in the most contested neighbourhood on earth. It would make the ten on stability and competence alone; geography and imports keep it out.

The scorecard

The same ten against the same five criteria, so you can see where each one is strong rather than taking a ranked list on faith. The High/Moderate/Low ratings are my assessment, not scores lifted from an index. The alliance facts in the neutrality column — NATO membership, EU membership, formal neutrality, no standing military — are matters of public record. That is the part of this table you should hold me to.

Read down the neutrality column and the tension in the whole exercise becomes obvious. The countries that feed and defend themselves best are mostly inside alliances, and the countries that are genuinely neutral mostly cannot feed or defend themselves. Nobody scores well on everything, and anyone telling you otherwise is selling.

I have kept this scorecard qualitative on purpose. The numeric version — food self-sufficiency ratios, share of electricity domestically generated, Global Peace Index rank — is the version I would rather publish. I will not put figures in a table until I can date them and cite them properly.

The ones people overlook

Here is where my own bias is relevant, so treat it accordingly — this is the region I work in.

Several Eastern Caribbean island nations score surprisingly well against those five criteria. They are small, non-aligned, of negligible strategic value, geographically isolated and politically stable. Critically, a few of them are among the very few places on earth where you can hold citizenship rather than a revocable permit.

Dominica is the strongest on self-sufficiency: abundant fresh water, serious agricultural land, and geothermal energy in development. I wrote about it as the region’s last true frontier market.

St. Kitts & Nevis combines low strategic profile with the world’s oldest citizenship-by-investment program, a stable legal system and a property market with actual depth.

The limits are real: these are small islands that import most manufactured goods and fuel. Hurricanes are an annual risk, and medical infrastructure is limited for anything serious. They are not a fortress; what they are is a legally accessible, low-profile, politically stable base — a different and more achievable thing.

The uncomfortable part

Three things worth saying plainly, because most articles on this topic skip them.

No country is immune. A genuinely global conflict disrupts trade, finance, communications and supply chains everywhere. "Safest" means relatively less affected, not untouched.

Nuclear risk does not respect distance the way conventional war does. Fallout, EMP effects and the collapse of global systems are not solved by being far away. Anyone selling geographic distance as a complete answer is overselling.

The real risk for most people is not war. It is currency crisis, capital controls, political instability, or simply being unable to leave when they want to. Those are far more probable, and the same preparation addresses them — which is the actual argument for a Plan B, and a much better one than war.

What a real Plan B looks like

This is the part I can speak to with some authority, because it is what I do.

It is also the part most people arrive at last and should arrive at first. Almost everyone who reaches this article typed some version of "where would be safe." Very few typed "how do I get a second passport before I need one." That is the same question with the fantasy removed, and the only version of it that has an answer you can act on. The country list above is context; what follows is the actual work, and it has a lead time measured in years.

Legal right of entry, secured in advance. This is the whole thing: in a crisis, borders close, visas stop being issued and flights fill. A tourist visa is not a plan. What works is permanent residency or citizenship, obtained years before you need it, when the process is calm and cheap rather than impossible. The distinction matters, because residency versus citizenship solve different problems, and citizenship is the only one nobody can revoke at a border.

Somewhere you would go. People acquire status in places they have never visited and would hate. If you would not spend a month there in ordinary times, you will not go there in extraordinary ones.

Assets outside a single jurisdiction. Property, banking and structures in more than one country — not exotic, just not all in one place. For families with real assets, that is where trusts and foundations come in.

Practical self-sufficiency where you would go. Water, power, and the ability to function for a period without imports. This is where the Caribbean’s realities cut both ways: excellent water and solar potential, poor manufactured-goods resilience.

Do it early, or not at all. Every route I work with — citizenship by investment, residency programs, property purchase — takes months to years. As at August 2026, processing on Caribbean citizenship runs well past a year on most of the five programs, and longer still on the slowest of them. That figure has moved in one direction only since 2023, so treat it as a floor rather than an estimate, and confirm the current position with the relevant Citizenship by Investment Unit. A Plan B assembled during a crisis is not a Plan B.

I will end where I started. I do not think you should organise your life around a third world war, and I am wary of anyone using that fear to sell something. But the same preparation that would help in an extreme scenario is straightforwardly useful in the ordinary ones — and that, not doomsday, is why the families I work with do it.

If you want to think through what a genuine second base looks like for your situation, apply for a private call, or start with who should buy a second citizenship — including the case for deciding you do not need one.

The ten, and the caveat

• The five criteria that matter: neutrality, isolation, self-sufficiency, deterrence and social stability.
• The ten, ranked: New Zealand, Switzerland, Iceland, Uruguay, Chile, Fiji, Ireland, Costa Rica, Australia, Canada — with Japan just outside.
• No country scores well on all five. The ones that feed and defend themselves are mostly inside alliances; the genuinely neutral ones mostly cannot feed or defend themselves.
• Food and energy self-sufficiency is the most underrated factor — supply chains break before borders do.
• Several Eastern Caribbean nations score well and, unusually, offer citizenship rather than a revocable permit.
• No country is immune; "safest" means relatively less affected.
• The realistic risks are currency crises, capital controls and instability — not invasion. Same preparation, far higher probability.
• Legal status must exist before a crisis. Every route takes months to years.

Frequently asked questions

Which country is safest in a world war? On the combined criteria of neutrality, isolation, self-sufficiency and stability, New Zealand and Switzerland score highest. New Zealand scores for isolation and food security, Switzerland for neutrality and civil-defence preparedness. My full ranked ten, as at August 2026, is New Zealand, Switzerland, Iceland, Uruguay, Chile, Fiji, Ireland, Costa Rica, Australia and Canada, with Japan just outside. It is a reasoned ordering rather than a computed index.

Which countries are on the list of the ten safest? New Zealand (1), Switzerland (2), Iceland (3), Uruguay (4), Chile (5), Fiji (6), Ireland (7), Costa Rica (8), Australia (9) and Canada (10). Japan falls just outside on import dependence and geography. Several Eastern Caribbean nations score better than their size suggests on neutrality, low strategic value and stability, though not on self-sufficiency.

Is any country completely safe in a nuclear war? No. Fallout, atmospheric effects and the collapse of global trade, finance and communications would reach everywhere. Southern-hemisphere countries far from likely targets — New Zealand, Uruguay, Chile — would be less directly affected, but no location offers immunity.

What makes a country safe during a global conflict? Political neutrality, geographic isolation, the ability to feed and power itself without imports, credible defence or deterrence, and internal social stability. Self-sufficiency is the most underrated of these, because supply chains fail long before borders are threatened.

Can you get citizenship somewhere safe before a crisis? Yes, and that is the point of doing it early. Several countries offer citizenship or residency by investment, including five in the Caribbean. Processing there, as at August 2026, runs well past a year on most programs and considerably longer on the slowest. Applying during a crisis is generally not possible, so the planning has to be done in calm conditions. This is the commercially useful version of the "safest country" question, and the only one with an answer you can act on.

Are Caribbean islands safe in a world war? They score well on neutrality, low strategic value, isolation and political stability, and a few offer full citizenship rather than a revocable permit. The limits are real: dependence on imported fuel and manufactured goods, annual hurricane exposure, and limited medical infrastructure.

Is planning for World War III sensible? Organising your life around it is not. But the same preparation — a second legal residence, assets in more than one jurisdiction, somewhere you would genuinely go — is useful against far likelier events. Those are currency crises, capital controls or political instability. That is the sounder reason to do it.
