When they explode, nuclear weapons release a lot of energy, burn everything around and kill thousands of people. That’s what happened in the Second World War, in 1945, when the United States dropped 2 nuclear bombs on Japan. The world discovered the horror of these weapons that are so dangerous for men and for the planet.
So… why do we still make nuclear weapons?
Today, 5 countries have nuclear weapons: the United States, Russia, France, the UK and China. Others are trying to make them like India, Pakistan or North Korea. It takes complicated technology and a lot of money to make nuclear weapons; countries think it shows their power. But those who have nuclear weapons don’t necessarily want to use them. The aim is to make other countries afraid. Because you think twice before attacking those who have them… Some countries say that making others afraid, keeps the peace. But …it doesn’t always work that way. The danger is if these nuclear weapons are stolen, go off accidentally… or even kill all life on Earth… So, for 50 years now, some countries are trying to agree to reduce the number of nuclear weapons. And more and more countries want to ban them, perhaps before 2030, …to have some peace at last!
