Across more than a hundred medical and health journals, editors have turned to the same question at once: what does the nuclear age ask of those who heal. Nine states spent nearly $119 billion on their arsenals in 2025, a rise of 19 percent, while models suggest that even a limited exchange could starve populations far from any battlefield.

Medical Journal Editors Urge Health Sector to Keep Nuclear Risk at the Center of Public Debate
Models cited suggest a limited nuclear war could cause global starvation affecting populations in megacities.
$3,768 every second on nuclear arsenals
Mark
Why are medical journals writing about nuclear weapons at all?
Mimi
Because the editors argue the consequences are a health matter. Their concern is what a nuclear war would do to people, and they want clinicians and researchers in the public debate.
Mark
The spending figure is striking. $3,768 per second.
Mimi
Yes, just under $119 billion in 2025 across nine states, up 19% from the year before. That is the authors' figure.
Luke
Worth saying it's the authors' calculation, and the piece doesn't tell us how it was built or who compiled the underlying data.
Mark
And the starvation claim? Two to three percent of weapons seems small.
Mimi
That's the point they make. Models suggest even a limited war could cause global starvation and civilizational collapse, especially with so many people in megacities.
Luke
Those are models, not evidence. The article doesn't say which models or what assumptions they rest on, so the confidence of the sentence outruns what we can check here.
Mark
What's genuinely new in the institutional picture?
Mimi
The UN review due in 2027 and the WHO update by 2029 are the first major reassessments by those bodies in nearly 40 years.
Luke
And the treaty news cuts both ways. Seventy-five countries are bound, but no nuclear-armed state has signed. The editorial is advocacy, and the pressure it describes hasn't yet changed that.
Der Puls
- Over 100 health journals have printed a single editorial, a rare show of unified alarm from the medical world.
- Nuclear-armed states poured just under $119 billion into arsenals in 2025, a 19% jump that the authors call a race in the wrong direction.
- Models suggest a limited nuclear war using 2-3% of warheads could trigger global starvation, threatening megacity populations.
- The TPNW review conference closes in 2026 with none of the nine nuclear-armed states signed on, leaving the treaty's reach in doubt.
- The UN and WHO are reopening nuclear war assessments due in 2027 and 2029, the first major reviews in nearly 40 years.
Across more than a hundred medical and health journals, editors have turned to the same question at once: what does the nuclear age ask of those who heal. Nine states spent nearly $119 billion on their arsenals in 2025, a rise of 19 percent, while models suggest that even a limited exchange could starve populations far from any battlefield. The editors ask that health remain at the center of public talk about these weapons, because the human body is where their consequences would finally be counted. Their plea sits between a treaty still waiting for the nuclear powers to sign and reviews that will not report until 2027 and 2029.
More than a hundred medical and health journals, from The BMJ and The Lancet to the National Medical Journal of India, have printed the same editorial. Its request is simple: doctors, nurses and researchers should keep health at the center of public conversation about nuclear risk, especially as geopolitical tensions grow.
The editors begin with money. In 2025 the nine nuclear-armed states spent just under $119 billion on their arsenals, a 19 percent increase over the year before. They then turn to consequences. Modeled projections suggest that even a limited nuclear war, using only 2 to 3 percent of existing weapons, could trigger global starvation and the collapse of modern civilization, a threat that would fall hardest on the large populations now living in megacities.
International bodies are beginning to look again. The UN General Assembly's comprehensive review is due in 2027, and the World Health Organization will update its studies by 2029, the first major reassessments by either body in nearly forty years. Meanwhile, 75 countries are legally bound by the Treaty on the Prohibition of Nuclear Weapons and 26 more have signed, but none of the nine nuclear-armed states has joined as the treaty approaches its review conference at the end of 2026.
The editors also challenge the case for deterrence, calling its security fragile and dependent on permanent catastrophe. Their conclusion is a call for a verifiable, deadline-driven agreement to eliminate nuclear weapons, and for the health sector to keep insisting that every country join the treaty.
More than 100 medical and health journals have printed the same editorial on the same subject: nuclear weapons, and the role of doctors, nurses and researchers in talking about them. It appears in The BMJ, The Lancet, the Medical Journal of Australia, the East African Medical Journal, the National Medical Journal of India and International Nursing Review, among others. The editors say they are responding to growing geopolitical tensions, and their request is plain. Health professionals should keep health at the center of public discussion about nuclear risk.
The authors begin with money. In 2025, the nine nuclear-armed states spent just under $119 billion on their arsenals, which works out to $3,768 every second. Those states are China, France, India, Israel, North Korea, Pakistan, Russia, the United Kingdom and the United States. The authors put the figure at a 19% increase over the previous year.
Then they turn to what the weapons could do. More than 12,000 nuclear warheads exist worldwide, and large populations now live in megacities. The authors cite models showing that even a "small" nuclear war, using only 2% to 3% of existing weapons, could set off global starvation and the collapse of modern civilization. These are modeled projections, not observed events.
International bodies are beginning to look at the question again. The United Nations General Assembly has started a comprehensive review of current knowledge about the consequences of nuclear war, due in 2027. The World Health Organization will update its studies on the public health effects of nuclear war by 2029. The authors note that these are the first major reassessments of the subject by either body in nearly 40 years.
Treaty work has also picked up, they say, especially around the Treaty on the Prohibition of Nuclear Weapons, or TPNW. Seventy-five countries are now legally bound by it, and another 26 have signed. But as the treaty approaches its first review conference at the end of 2026, none of the nine nuclear-armed states has signed or ratified it, despite rising pressure.
The editors also take on the main case for keeping the weapons: that deterrence prevents nuclear war. They call the security it offers fragile and asymmetric, dependent on the permanent threat of catastrophe, and blind to the needs of non-nuclear states. They add that insights from psychology and neuroscience suggest decisions about nuclear weapons are not rational. Emerging AI and drone technologies, along with misinformation and disinformation, raise the risk further.
Their conclusion is a demand for a verifiable, deadline-driven agreement to eliminate all nuclear weapons. To safeguard human survival, they write, the health sector must keep insisting that every country, nuclear-armed states included, join the TPNW. The next markers are the treaty's review conference at the end of 2026, the UN review in 2027 and the WHO update by 2029.
