CHICAGO \u2212 In the fall of 2022, U.S. spies said the chances of Russia using tactical nuclear weapons against Ukraine<\/a> were 50% \u2212 a coin flip.
Nearly three years later, the risk of nuclear war has only increased, top experts say. The Bulletin of the Atomic Scientists’<\/em> famed “Doomsday Clock” is the closest it has ever been<\/a> to midnight.
Humanity is \u201cheading in the wrong direction\u201d on the one threat that \u201ccould end civilization in an afternoon,\u201d warned an assembly of Nobel laureates, nuclear experts, and diplomats gathered at the University of Chicago to mark the 80th anniversary of the planet\u2019s first nuclear explosion<\/a> in 1945 when the U.S. conducted the Trinity test in New Mexico.
Although Russia didn\u2019t nuke its neighbor, the brutal war of attrition continues in Ukraine.
Two nuclear-armed countries, India and Pakistan, attacked each other<\/a> in May. The U.S. and Israel<\/a>, which both have nuclear weapons, bombed Iran in June to destroy its nuclear program<\/a>. Popular support for building nuclear weapons grows<\/a> in countries like Japan and South Korea.
Against this backdrop, more than a dozen Nobel Prize winners and numerous nuclear experts signed a \u201cDeclaration for the Prevention of Nuclear War<\/a>\u201d on July 16 with recommendations for world leaders to reduce the increasing risk of nuclear conflict.
\u201cDespite having avoided nuclear catastrophes in the past, time and the law of probability are not on our side,\u201d the declaration says. \u201cWithout clear and sustained efforts from world leaders to prevent nuclear war, there can be no doubt that our luck will finally run out.\u201d
The declaration emerged from days of discussion and debate, said assembly leader David Gross, a University of California, Santa Barbara, physicist and 2004 Nobel Prize winner.
\u201cWe are calling on our leaders in the world to consider our suggestions and heed our warnings,\u201d Gross said.
Longtime Vatican diplomat and nuclear advisor Cardinal Silvano Maria Tomasi argued that faith leaders should embrace a role in providing world leaders with independent moral and ethical assessments of nuclear policy and technology.
The declaration and speakers at its unveiling spoke extensively of the crucial role diplomacy and treaties played in building trust between countries with nuclear weapons and shrinking their arsenals after the Cold War.
But a key treaty remains unenforced, and the last remaining arms control agreement between the U.S. and Russia expires in February 2026.
The Comprehensive Nuclear Test Ban Treaty, or CTBT, is a 1996 international agreement that aims to ban explosive nuclear tests.
Although the CTBT Organization, headquartered in Vienna, Austria, successfully detects even underground nuclear tests (and identifies when suspicious seismic events aren\u2019t<\/em> test explosions), the treaty is not in force. Nine more countries, including the U.S. and Russia (which de-ratified the CTBT in 2023), must formally approve the treaty before it becomes binding international law.
At the assembly, CTBTO leader and former Australian diplomat Robert Floyd joined the Nobel winners in calling the international community to formally approve the testing ban.
Floyd argued that if countries with nuclear weapons resumed testing to build more destructive nukes, it could lead \u201cother states to develop nuclear weapons and \u2026 a renewed global nuclear arms race.\u201d
The declaration also highlighted the need for the U.S., Russia, and China to enter arms control discussions. The 2010 New START treaty, which limits American and Russian nuclear weapons deployments and enables the rivals to verify the other\u2019s cooperation, expires in February 2026.
Artificial intelligence and its role in nuclear weapons matters also weighed heavily.
The declaration emphasized the \u201cunprecedented and serious risks posed by artificial intelligence\u201d and implored \u201call nuclear armed states to ensure meaningful and enhanced human control and oversight over nuclear command and control.\u201d
Tomasi, the Vatican\u2019s representative, said scientists, disarmament experts and faith leaders need to study \u201cthe ethical implications of emerging technologies,\u201d such as AI, on \u201cnuclear stability.\u201d
World leaders, including former President Joe Biden and Chinese President Xi Jinping<\/a>, generally agree that humans \u2212 and not AI algorithms \u2212 should control nuclear launch buttons.
But debate rages over the ideal, and safe, extent of integrating AI into other nuclear functions such as early warning, targeting, and communications.
A February 2025 report<\/a> from the Center for a New American Security think tank on AI nuclear risk warned that \u201coverreliance on untested, unreliable, or biased AI systems for decision support during a crisis\u201d could potentially lead decision-makers down an escalatory path during a nuclear crisis.
Ultimately, argued Nobel winner Gross, progress in reducing the risks of nuclear weapons hinges on popular pressure on world leaders.
\u201cThe main motivation for the advances in reducing the risk of Armageddon was the fear of many \u2026 people throughout the world who demanded (action) from their leaders,\u201d Gross said.
