Rising tensions after U.S. and Israeli airstrikes on Iran have revived fears of a wider global conflict and the question of where people might be safest in a nuclear war. The anxiety echoes Cold War memories, when “duck and cover” drills offered more comfort than real protection. Today, the threat feels just as real, even if the geopolitical landscape has changed.
U.S. officials, including President Donald Trump, claim Iran has restarted its nuclear program and could rapidly build a bomb, though reporting by *The New York Times* says these claims remain disputed. Despite this uncertainty, joint strikes hit major Iranian cities, and some reports allege that Supreme Leader Ayatollah Ali Khamenei was killed. Analysts warn that retaliation could target U.S. nuclear infrastructure, sharply raising the risk of catastrophic escalation.
The U.S. stores about 2,000 nuclear warheads, mostly in missile silos across Montana, North Dakota, and Nebraska, with smaller stockpiles in Wyoming and Colorado. These areas would likely be primary targets. Studies estimate radiation levels could reach up to 84 gray (Gy), far beyond lethal levels, leading experts to suggest that areas farther from silos may offer slightly better short-term survival odds.
States considered lower risk include much of the Northeast, Mid-Atlantic, Southeast, and parts of the Midwest, along with Washington, Utah, New Mexico, and Illinois. However, experts stress that “lower risk” does not mean safe, as fallout patterns depend on wind, strike scale, and the number of detonations.
Long-term survival poses even greater challenges. *Scientific American* warned that strikes on silo regions would devastate farmland, while nuclear winter could collapse global agriculture. Journalist Annie Jacobsen said, “Places like Iowa and Ukraine would just be snow for 10 years,” adding, “So agriculture would fail, and when agriculture fails, people just die.” She suggested New Zealand and Australia might fare better due to agricultural resilience.
Ultimately, experts agree there is no truly safe place in a full-scale nuclear war. Modern arsenals could reshape the planet’s climate, disrupt food systems, and cause lasting global devastation, leaving no real winners—only varying degrees of loss.
