They’re the most dangerous invention the world has ever seen. Can we prevent them from being used again?
What we're facing

nuclear weapons in the world's arsenals
Today, some 12,700 nuclear weapons remain in the world’s arsenals, with about 90 percent owned by the United States and Russia. Both countries are actively planning to build new weapons, sparking a 21st century arms race and increasing the risk of nuclear war.
Meanwhile, many of the Cold War’s most absurd and dangerous nuclear policies remain unchanged. In the United States, the president can order the launch of nuclear weapons without consulting anyone—in essence, starting a nuclear war.
These policies and plans threaten the world in very real ways, and they need to change. You can help.
