The signing of the Non Proliferation Treaty
After the Cuban Missile Crisis occurred the United Nations saw a growing need to stop the proliferation of nuclear weapons. The Nuclear Non Proliferation Treaty (NPT) is a treaty that's purpose is to stop the spread of nuclear weapons to non-nuclear powers and to deconstruct the nuclear weapons of the nuclear superpowers. The treaty was opened for signing in 1968, and came into effect in 1970. The Non-Proliferation Treaty promotes the use of nuclear energy for peaceful purposes such as providing power. A total of 190 countries, including the five nuclear powers, Russia, France, China, United Kingdom, and the US, have signed the treaty.
Today the treaty has done much in the way of nuclear weapons and technology. It has given safer guidelines on how to work with nuclear power. The treaty, however, has not been completely successful in stopping the spread of nuclear weapons. Countries like North Korea and Iran have been attempting to develop nuclear weapons for some time. This has been a huge negative impact on the world in regards that now we could be under a threat of nuclear war.
