Who has 90% of the world’s nuclear weapons?
The exact number of warheads is secret, so these are some of the best estimates based on publicly available information, historical records, and occasional leaks. Nine countries are thought to have nuclear weapons today, but over 80% of warheads are held by just two: Russia and the United States. Russia has the most confirmed nuclear weapons, with over 5,500 nuclear warheads. The United States follows behind with 5,044 nuclear weapons, hosted in the US and 5 other nations: Turkey, Italy, Belgium, Germany and the Netherlands.
