When an atom is split, a great amount of energy is released. This is nuclear fission, and it can be used as a source of electricity or it can be used to destroy. Since the discovery of nuclear fission and the invention of atomic bombs, the world has lived in fear of nuclear war. Such bombs destroy huge areas when they explode, but they also send radiation and small bits of stuff into the air. It then moves around the world on the wind and poisons the environment.
That’s why it’s important for world leaders to get along well enough to agree not to drop such bombs on each other. In 1985, an agreement was signed called the Nuclear Nonproliferation Treaty, or NPT. The nations that signed it agreed to reduce the nuclear weapons and to work together for safe and peaceful nuclear energy. But North Korea didn’t stick to the agreement and secretly continued to grow its nuclear program.
President Donald Trump has done something no other United States president has done in the past. He has personally gone to North Korea to try to make peace with the country’s leader, Kim Jong-un, and to put an end to the North Korean nuclear weapons project. President Trump has already met with Kim Jong-un twice. There is a lot of tension between the two countries, but when the leaders talk, they seem to get along. Still, the two leaders haven’t come to a final agreement yet. Kim Jong-un recently sent a letter to President Donald Trump, inviting him to North Korea to talk once again. This is a good step in coming to an agreement.
North Korea has reached agreements with the United States and the United Nations before, but then ignored the agreement in secret. But the fact that Kim Jong-un is the one who reached out to Donald Trump gives some hope that progress can be made and a peaceful agreement can be made.
