A Massive and Dangerous Arsenal
Right now, Earth is home to more than twelve thousand seven hundred nuclear weapons. Most of them belong to two countries, the United States and Russia. The rest are held by nations including China, France, the United Kingdom, Pakistan, India, Israel, and North Korea.
Even the smallest of these weapons can destroy an entire city. A single detonation would bring unimaginable suffering. At first glance, sending these devices off the planet seems like a smart way to protect ourselves. But the plan is not as safe or simple as it might appear.
