Nuclear Weapons
The world’s nuclear powers have more than 12,000 nuclear warheads. These weapons can kill millions directly and, through their impact on agriculture, likely have the potential to kill billions .
Nuclear weapons killed between 110,000 and 210,000 people when the United States used them against the Japanese cities of Hiroshima and Nagasaki in August 1945. 1 They have come close to being used again more than a dozen times since.
This is why countries have worked to limit the proliferation and number of nuclear weapons.
On this page, you can find writing, visualizations, and data on how many states have nuclear weapons, how many warheads they possess, how many oppose them, and how this has changed over time.
