UN chief warns of greatest threat of nuclear disaster since the end of the Cold War.
The Treaty on the Non-Proliferation of Nuclear Weapons is credited with keeping the world safe.
Nearly every country has signed the agreement, which aims to prevent the proliferation of nuclear weapons and promote the peaceful use of nuclear technology.
But the United Nations Secretary-General warns that the world is only one dangerous miscalculation away from a nuclear conflict.
Antonio Guterres says the threat is at its highest level since the end of the Cold War.
Nuclear-armed powers, including the United States, have called for disarmament.
But do they have the will to eliminate nuclear weapons?
