Russia’s invasion of Ukraine under President Vladimir Putin has brought global fears of a possible nuclear war. This geopolitical crisis’s escalation has also brought back serious discussions about the devastating consequences that could unfold if tensions escalate into nuclear warfare. The threat of nuclear warfare currently seems distant to many Americans; however, experts warn that major U.S. cities are at higher risk of being targeted in such a scenario. It is unlikely Russia and the U.S. will escalate to nuclear warfare over Ukraine. However, if nuclear conflict erupted between the superpowers, it could be catastrophic for the entire planet.
Russia’s Nuclear Arsenal Poses an Unprecedented Threat
Russia is currently the world’s largest nuclear weapons stockpile owner, possessing approximately 4,380 warheads in its military arsenal as of early 2024. According to the Federation of American Scientists, an additional 1,200 retired warheads await dismantlement. This brings Russia’s total inventory to roughly 5,580 nuclear weapons. Combined with the United States, both the U.S. and Russia own 87% of the world’s total inventory of atomic weapons. Approximately 83% of those warheads are stockpiled, ready for military use.
This concentration of destructive power in two nations creates a precarious global situation. Russia has continued modernizing its nuclear forces despite economic sanctions and international pressure following the Ukraine invasion. President Putin has repeatedly made veiled nuclear threats throughout the conflict, lowering the threshold for potential use in an updated doctrine released in November 2024. These developments have created what President Biden described in October 2022 as the highest nuclear risk since the Cuban Missile Crisis of 1962.
Major U.S. Metropolitan Areas Would Be Primary Targets

In the event of a nuclear conflict involving Russia, several major American cities are at significant risk of being targeted. New York, Chicago, Houston, Los Angeles, San Francisco, and Washington, D.C. would likely be among the first locations struck by Russian intercontinental ballistic missiles. These metropolitan areas house crucial government infrastructure, financial centers, and dense populations that make them strategic and devastating targets for the Russians. A map created using Federal Emergency Management Agency data and National Resources Defense Council information identifies these cities as probable first-strike locations. The map, originally compiled by journalist John Dodge in 2015 and reevaluated by The Independent in 2023, shows disturbing patterns of vulnerability across the nation.
Washington, D.C., a Primary Target

Washington, D.C., would most likely be targeted in the primary wave of attack, as it houses the core of the U.S. government and military command and control. The nation’s capital houses the Pentagon, White House, and countless defense-related facilities that Russia would target to weaken the the U.S. defense forces. New York City would be a target as it is America’s financial center. It also holds the U.S.’s largest population concentration, with over 8 million residents in New York City. Los Angeles and San Francisco would face targeting as they house major populations and economic hubs on the West Coast. Chicago’s central location and status as America’s third-largest city make it another inevitable target. Houston’s concentration of energy infrastructure and petroleum refining capacity adds strategic value as a Russian target.
Following an initial attack on major cities, Russian missiles would begin targeting more populous areas and other critical infrastructure across America. Radioactive fallout from distant nuclear strikes could contaminate almost all of California and much of coastal New England. Fallout from strikes on military bases and densely populated areas could heavily damage communities across the entire state of Florida.
Nuclear Missile Fields Create Target Clusters in Western States

Colorado, Montana, North Dakota, and Wyoming would all be targeted by Russia because these states house America’s intercontinental ballistic missile arsenal. 400 Minuteman III missiles sit in underground silos stretching across these 5 states, including small portions of Nebraska. These missile fields at Malmstrom Air Force Base in Montana, Minot Air Force Base in North Dakota, and F.E. Warren Air Force Base in Wyoming form the land-based leg of America’s nuclear triad. Russia would target these silos to eliminate America’s ability to launch any retaliatory strikes.
Scientific modeling based on open source data from the Federal Emergency Management Administration (FEMA) and the National Resources Defense Council was used by Dodge to plot likely Russian nuclear targets. It also shows that a concentrated nuclear attack on these existing U.S. silo fields would annihilate all life in the surrounding regions. Minnesota, Iowa, and Kansas would be subjected to high levels of radioactive fallout despite being outside the direct strike zones. Acute radiation exposure alone could cause several million fatalities across the central United States. The fallout would contaminate fertile agricultural land for years, devastating America’s food production capacity. Western Texas, most of Nevada, and Michigan would be relatively clear of immediate fallout, though long-term nuclear winter effects would still impact these regions.
Nuclear Power Plants Represent Critical Vulnerabilities

Approximately 94 nuclear reactors operate at commercial power plants across 30 U.S. states, which are significant potential targets in a nuclear conflict. Some of the larger nuclear facilities experts identify as vulnerable include active plants in Alabama, Arizona, Maryland, New Jersey, Pennsylvania, and Tennessee. The Vogtle Electric Generating Plant in Georgia is currently the largest nuclear facility in the United States, with four reactors producing 4,664 megawatts of capacity. Palo Verde in Arizona ranks second with three reactors generating 3,937 megawatts, while Browns Ferry in Alabama produces 3,775 megawatts from 3 reactors. These facilities contain radioactive materials and spent fuel that could create catastrophic secondary contamination if struck by nuclear weapons.
Russia might target nuclear power plants to maximize long-term environmental damage and render large American regions permanently uninhabitable. The concentration of nuclear plants in the eastern United States creates particular vulnerability, with multiple facilities in Pennsylvania, including Susquehanna, Peach Bottom, and Limerick plants. Illinois hosts several major nuclear installations, including Byron, Braidwood, and LaSalle stations, that could be targeted. Tennessee’s Sequoyah and Watts Bar plants, New Jersey’s Salem facility, and numerous reactors along the East Coast are all under threat if nuclear warfare breaks out.
The United Kingdom Faces Similar Devastation Risks

The United Kingdom has been a staunch supporter of Ukraine since the Russian invasion in 2022, providing military aid and imposing severe economic sanctions on Moscow. This is why it is most likely that the United Kingdom would be a potential target for a Russian nuclear attack if conflict erupts between the U.S. and Russia. According to a report by Newsweek, Russian officials threatened to bomb the United Kingdom at least 35 times between February and July 2022 alone.
Cold War-era maps discovered in Britain’s National Archives reveal which cities Russian forces planned to target during that era. Central London, Edinburgh, Teesside, Leicester, Manchester, Liverpool, Glasgow, Hull, York, Dover, Cambridge, Maidstone, Huddersfield, Wolverhampton, Coventry, and Sheffield all appeared on historical target lists. Experts believe these targets have changed little in the decades since, as they still house population-dense centers and important infrastructure. London alone could expect up to 4-5 megaton bombs, according to declassified government documents from the Cold War period. Glasgow and Edinburgh were expected to endure two blasts each of similar magnitude, which were 333 times more powerful than the Hiroshima bomb.
Cold War-era Maps Reveal Targets

The Cold War-era maps also revealed 23 Royal Air Force bases, 14 U.S. Air Force bases, 10 radar stations, 8 military command centers, and 13 Royal Navy bases would face targeting. This comprehensive strike plan would essentially blanket the entire British Isles in nuclear destruction and radioactive fallout. The naval base at HMNB Clyde, home to Britain’s submarine-based nuclear deterrent, would certainly be among the highest priority targets. An adversary would likely strike RAF Fylingdales in North Yorkshire first to blind British and American detection capabilities. The concentration of military and population targets in such a small geographic area means virtually nowhere in the United Kingdom would escape the effects of nuclear war.
NATO Allied Countries Would Face Widespread Targeting

While concrete data on which NATO countries Russia would target remains classified, Russian officials have made their intentions clear through public statements. Dmitry Rogozin, former head of Russia’s Roscosmos space agency, declared in May 2022 that “in a nuclear war, NATO countries will be destroyed by us in half an hour”. This provocative claim, while potentially exaggerated, reflects Russia’s view of NATO as an existential threat. The statement makes all NATO member states extremely dangerous places to be if nuclear conflict erupts between Russia and the United States.
Russia has been expanding its nuclear capabilities into neighboring Belarus, increasing the number of tactical weapons deployed at NATO’s border. Moscow announced in March 2023 that it would station tactical nuclear weapons in Belarus through Iskander short-range ballistic missiles and gravity bombs for fighter aircraft. Belarus confirmed receipt of these weapons in December 2023, marking the first time Russia placed nuclear arms outside its borders since the Soviet Union collapsed. This deployment mirrors NATO’s nuclear sharing practice, in which NATO stations U.S. weapons in Belgium, Germany, Italy, the Netherlands, Turkey, and, recently, again in the United Kingdom.
President Putin modified Russia’s nuclear doctrine in November 2024, stating that Russia would treat a conventional attack by an ally of a nuclear state as grounds for launching a nuclear strike. This lowered threshold means any NATO country providing military support to forces attacking Russia could face nuclear retaliation. The doctrine creates ambiguity about the exact conditions triggering nuclear use, allowing Putin maximum flexibility while maximizing NATO’s uncertainty. Germany, Poland, France, and other NATO allies actively supporting Ukraine face particularly elevated risks under this expanded doctrine.
Presidential Warnings Highlight Armageddon Scenarios

President Joe Biden issued his most blunt warning about nuclear war risk in October 2022, stating the world could face “Armageddon” if Putin uses tactical nuclear weapons. Speaking at a Democratic fundraiser in New York, Biden said: “For the first time since the Cuban Missile Crisis, we have a direct threat of the use of nuclear weapons”. The President’s remarks reflected highly classified intelligence indicating that Russian military officials were discussing the potential deployment of tactical nuclear devices in Ukraine. The CIA reportedly assessed that, although it detected no weapons movements at that time, the probability of nuclear use could surge to 50 percent or higher if Ukrainian forces appeared poised to reclaim Crimea.
Biden warned Putin that using even one tactical nuclear weapon would trigger devastating consequences for Russia. The President stated he was “trying to figure out what is Putin’s off-ramp” and where the Russian leader could “find himself in a position that he does not only lose face but lose significant power within Russia”. These concerns reflected the dangerous dynamic where battlefield losses might push Putin toward nuclear escalation. Biden’s characterization of the nuclear threat as the worst since 1962 was not mere rhetoric but based on concrete intelligence assessments of Russian military planning.
The United States and its NATO allies have repeatedly warned Russia that nuclear weapons use would lead to catastrophic consequences, though officials carefully avoid specifying exact responses. NATO Secretary-General Jens Stoltenberg stated that the alliance would “not engage in that same kind of reckless and dangerous nuclear rhetoric as President Putin”. British officials indicated Russia would face “devastating” consequences for nuclear use, though they emphasized any response would likely be non-nuclear. This deliberate ambiguity aims to deter Russian nuclear use while avoiding escalatory rhetoric that could make conflict more likely.

Nuclear Winter Would Cause Global Famine and Mass Death

Even a limited nuclear conflict could trigger worldwide famine through a phenomenon called nuclear winter, according to peer-reviewed research published in 2022 and 2023. Soot from burning cities would encircle the planet and cool it by reflecting sunlight back into space for years. This dramatic reduction in sunlight would cause global temperatures to plummet and crop yields to collapse across every continent. Research published in Nature Food found that a full-scale nuclear war between the United States and Russia could inject 150 million metric tons of soot into the stratosphere. This smoke would persist for 10 to 15 years, causing temperatures to drop by as much as 16 °C globally.
Scientists using climate and crop models estimate that more than 5 billion people would die from starvation in the aftermath of a full-scale U.S.-Russia nuclear war. This would equate to approximately 63% of the world’s current population perishing from just famine alone. Countries in Africa and the Middle East that depend heavily on food imports would face the worst outcomes, with nearly complete population losses in many regions. Even nations not directly involved in the conflict would see massive die-offs as agricultural production collapsed. India and Pakistan alone could lose more people to famine than the number killed in the actual combatant countries.
Relatively Safe: Australia and New Zealand

Australia and New Zealand would fare relatively better than other regions because they would avoid most bombs dropped in the Northern Hemisphere and rely on wheat crops somewhat more tolerant of cooler climates. However, even these nations would face severe challenges as global trade collapsed and temperatures dropped worldwide. The research makes clear that maintaining international food trade and rapidly implementing resilient food production strategies would be essential to preventing complete societal collapse. Without these adaptations, nuclear winter could trigger famines exceeding even the catastrophic direct casualties from nuclear weapons themselves.
The Reality Is That Nowhere Would Be Truly Safe

The sobering conclusion from extensive scientific research is that no place on Earth would be truly safe in a full-scale nuclear war between Russia and the United States. Even countries not directly involved in the conflict would face existential threats from nuclear winter, crop failures, and resulting famines. The interconnected nature of global food systems means that agricultural collapse in major producing regions would cascade globally within months. Researchers emphasize that preventing nuclear war must be the primary objective, as response and resilience measures alone cannot save most of humanity.
The nuclear threat that emerged during the Cold War never truly disappeared despite decades of arms reductions. Today’s geopolitical tensions, combined with massive nuclear arsenals, create conditions where a single miscalculation could trigger catastrophe. This reality should motivate continued efforts toward diplomacy, arms control, and policies that reduce rather than increase nuclear dangers. The alternative is, unfortunately, a world where 5 billion people perish from famine while survivors struggle in a devastated environment.
