The Nuclear Threat

There are 14,000 nuclear weapons on Earth. The US has about 5.8K, Russia 6.3K, and the rest are distributed between France, China, the UK, Pakistan, India, Israel, and North Korea*.

There are about 4,500 cities with at least 100,000 people. Even if you assume 3 bombs per city (as some are bigger than others), every city on Earth would be destroyed in an all-out global nuclear conflict.

This would kill roughly 3 billion people, or half of humanity almost immediately. Then there would be the fallout, the radiation sickness, the nuclear winter, the failure of food, water, and medical supplies, and the collapse of society as we know it.

And the living would envy the dead.

We're 100 seconds away.
