This graphic, via Visual Capitalist's Bruno Venditti, visualizes the world's nuclear powers based on data from the Federation of American Scientists. The exact number of nuclear weapons each country possesses is a closely guarded national secret, so the estimates presented here come with significant uncertainty.

Nuclear Powers

Despite reductions since the Cold War, the global nuclear arsenal remains significant. The U.S. and Russia together hold around 88% of the world's nuclear weapons and 84% of the warheads ready for military use. Combined, both countries have over 10,000 warheads. A 2018 study suggests that 100 nuclear weapons would be the "pragmatic limit" for any country's arsenal.

While the U.S. has been reducing its nuclear arsenal, Russia, China, India, Pakistan, and North Korea are increasing their warhead stockpiles.
