Earth’s doomsday inventory: Why 12,000 nukes could kill us 40 times over

Forget 12,000 warheads—just 100 to 300 detonations could erase modern civilization. That’s all it takes to trigger famine, blackout skies, and collapse economies worldwide.

Scientists say an all-out U.S.-Russia nuclear war wouldn’t just kill millions on impact—it could starve 5 billion people through nuclear winter and global agricultural collapse.  

Just 150 nukes over cities could block 20% of sunlight for a decade. Crops would fail, temperatures would crash, and hunger—not radiation—would be humanity’s main killer.  

Radiation isn’t the worst part. The real killer is famine. Smoke from city fires could choke the sky, causing crop failure on a scale never before seen in human history.  

There are over 12,000 nuclear warheads on Earth. Scientists agree: we only need a few hundred to end the world. Why are we stockpiling extinction?  

Russia holds the most nuclear warheads—over 5,500. The U.S. is close behind. Together, they hold nearly 90% of the world’s doomsday devices.  

Even North Korea’s estimated 50 warheads could devastate global climate if used strategically. In the nuclear game, size isn’t everything—placement is.  

Most warheads are never meant to be used. Their real purpose? Psychological leverage, deterrence, and the illusion of control over global annihilation.  

There’s no “safe” nuclear war. Even a so-called “limited” exchange could end civilization. The only true insurance policy is total abolition—before someone tests the odds.
