Forty-four years after the nuclear Non-Proliferation Treaty (NPT) came into force, the world still finds itself perilously close to the edge of the nuclear cliff. The cliff is perhaps not quite as steep as it was in the 1980s, when there were more than 70,000 nuclear weapons compared to today's 17,000, but going over it would be fatal for planet Earth.
Authoritative road maps exist to walk us back to the relative safety of a denuclearized world, but a perverse mixture of hubris and arrogance on the part of the nine nuclear-armed states (China, France, India, Israel, North Korea, Pakistan, Russia, the United Kingdom and the United States) exposes us to the risk of sleepwalking into a nuclear disaster.
For nuclear peace to hold, deterrence and fail-safe mechanisms must work every single time. For nuclear Armageddon to break out, deterrence or fail-safe mechanisms need to break down only once. This is not a comforting equation.
