What A World Without Nuclear Weapons Would Free In Resources And Psychology

As of 2024, the global nuclear stockpile is distributed roughly as follows (Stockholm International Peace Research Institute estimates):

- Russia: ~5,889 warheads (1,674 deployed) - United States: ~5,244 warheads (1,770 deployed) - China: ~410 warheads (expanding rapidly) - France: ~290 warheads - United Kingdom: ~225 warheads - Pakistan: ~170 warheads - India: ~164 warheads - Israel: ~90 warheads (undeclared) - North Korea: ~40-50 warheads (estimated)

"Deployed" means mounted on missiles or stored at bases, ready to launch within minutes. The U.S. and Russia each keep roughly 900 warheads on hair-trigger alert — they can be launched within 15 minutes of a presidential order. There is no second vote. No congressional approval. No judicial review. One person decides.

The destructive capacity of these arsenals is difficult to comprehend in human terms. A single W88 warhead — the standard U.S. submarine-launched weapon — has a yield of 475 kilotons. The bomb that destroyed Hiroshima was 15 kilotons. A W88 is roughly 30 Hiroshimas.

A single Ohio-class submarine carries 20 Trident II missiles, each with up to 8 warheads. That's 160 warheads on one vessel. One submarine could destroy every major city in a continent.

The United States has 14 such submarines.

The Congressional Budget Office estimated in 2023 that the U.S. will spend $756 billion on nuclear forces over the decade from 2023-2032. The full 30-year modernization program, including new intercontinental ballistic missiles (the Sentinel program), new submarines (Columbia-class), new bombers (B-21 Raider), new warheads, and updated command and control systems, is projected at $1.7 trillion.

Globally, the International Campaign to Abolish Nuclear Weapons (ICAN) documented $82.9 billion in nuclear weapons spending in 2022 across the nine nuclear-armed states.

For comparison: - $83 billion/year is more than the entire annual budget of the UN system - It's roughly double what the world spends on international development aid - It would fund the WHO's recommended package of essential health services for the 47 poorest countries - It would build 2 million affordable housing units per year - It would cover the annual cost gap for achieving universal primary education globally

These are not hypothetical trade-offs. Every dollar spent maintaining nuclear arsenals is a dollar not spent on something else. Economists call this opportunity cost. Moralists call it a choice.

This is the dimension that rarely gets discussed in policy circles, and it may be the most important one.

Normalization of extinction risk. Since 1945, every human being on Earth has lived under the possibility of nuclear annihilation. Not as a distant, abstract risk — as an operational reality maintained by standing military orders. The Bulletin of the Atomic Scientists' Doomsday Clock, as of 2024, stands at 90 seconds to midnight — the closest it has ever been.

What does it do to a species to live like this?

Robert Jay Lifton's research on nuclear psychology — beginning with his studies of Hiroshima survivors and extending to general populations — identified a phenomenon he called "psychic numbing." When a threat is too large and too constant, the mind doesn't process it through normal fear responses. Instead, it goes numb. People know intellectually that nuclear war could happen. They don't feel it. They can't afford to. So they develop a background dissociation — a low-grade detachment from the future that pervades planning, investment, and imagination.

Deterrence as worldview. Nuclear deterrence theory — mutually assured destruction, or MAD — is built on a specific model of human relationships: the only thing preventing annihilation is the threat of counter-annihilation. Trust is irrelevant. Cooperation is secondary. The fundamental relationship between major powers is one of mutual hostage-taking.

This worldview leaks. If the most powerful nations on Earth organize their deepest security around threat rather than trust, that framing shapes everything downstream. International institutions, trade relationships, immigration policy, climate negotiations — all of them are influenced by a baseline assumption that the world is fundamentally adversarial and that safety comes from strength, not solidarity.

The imagination deficit. Perhaps the deepest cost is to the collective imagination. When extinction is always on the table, it becomes difficult to plan in truly long-term ways. Why build institutions meant to last a thousand years when a single miscalculation could end everything tomorrow? Nuclear weapons create a psychological ceiling on civilizational ambition.

The Treaty on the Prohibition of Nuclear Weapons (TPNW) entered into force in 2021. As of 2024, 93 states have signed and 70 have ratified it. None of the nuclear-armed states have signed. None of their NATO allies have signed.

The treaty establishes a comprehensive prohibition on nuclear weapons — their development, testing, production, stockpiling, transfer, use, and threat of use. It represents the will of the majority of the world's nations.

The nuclear-armed states dismiss it as irrelevant because it doesn't include them. But the same was said about the conventions banning landmines and cluster munitions, both of which changed state behavior and norms even among non-signatories.

The abolition argument is not that disarmament is easy. It is that the alternative — perpetual maintenance of arsenals capable of ending civilization, in the hands of fallible institutions led by fallible humans — is not sustainable over centuries. It is a bet that nothing will ever go wrong. Given enough time, that bet loses.

Beyond the material benefits — the redirected resources, the reduced risk — nuclear disarmament would constitute a civilizational decision of a different order.

It would mean: we have decided that our security depends on each other, not on the capacity to destroy each other. We have decided that trust, imperfect and effortful as it is, is a better foundation than terror. We have decided that the future matters enough to remove the single greatest threat to it.

This is Law 1 in its most demanding form. "We are human" is easy to say when the stakes are low. Saying it while dismantling the machinery of annihilation — that's the real test.

1. The fifteen-minute exercise. Set a timer for fifteen minutes. That's roughly how long it takes from a launch order to detonation on a target thousands of miles away. Sit with the knowledge that this is the timeframe in which civilization could end. Notice what your body does with that information.

2. Budget reallocation. Research your country's nuclear weapons spending (or, if your country isn't nuclear-armed, its spending on alliance contributions to nuclear states). Write down three things that money could fund instead. Be specific. Names of programs, numbers of people served.

3. The Hiroshima reading. Read one first-person account from a Hiroshima or Nagasaki survivor. Not an analysis. Not a documentary summary. A person's words about what happened to them. Let it be specific. The abstraction is how numbing works.

4. Future letter. Write a letter to a person who will be alive in 2124 — one hundred years from now. Tell them what the world's nuclear arsenal looks like today. Tell them what you think about it. Consider what they might think about your generation's choices.
