Imagine a bomb so powerful it could wipe out an entire city in just seconds—that’s what nuclear weapons are. They unleash an enormous amount of energy through nuclear reactions, causing devastation not just from the explosion, but also from intense heat and dangerous radiation that lingers long after. Countries started building these weapons, especially during tense times like the Cold War, mainly to defend themselves and keep others from attacking.
It’s no wonder people are deeply afraid of nuclear weapons. Just one can kill millions and leave the environment damaged for decades. The radiation can even cause diseases, cancer, and genetic problems that are passed on through generations. Nations like the United States, Russia, China, and India hold on to these weapons for what they call strategic security.
That’s why world leaders are always talking about how to control them—because if a big nuclear war ever broke out, the damage wouldn’t just stop at borders or economies.
