But many other countries, including the U.S., have known stockpiles of nuclear weapons.

More than two dozen nations have nuclear power. Only nine possess actual nuclear weapons: Russia, the United States, China, India, Israel, France, North Korea, Pakistan and the United Kingdom.

The Ploughshares Fund, a global security foundation, estimates there are more than 15,000 nuclear weapons around the world; the U.S. and Russia possess 93 percent of them. The former Cold War foes keep nearly 2,000 nuclear weapons at the ready for immediate launch against each other, according to the Nuclear Threat Initiative.
