Kim Jong Un is the leader of North Korea. He wants to make the military stronger. This is called Aufrüstung. It means building more weapons. He says: We need weapons for our protection. He blames the USA and South Korea for danger. He says: These countries risk a nuclear war.
A new submarine is one reason. South Korea plans a submarine with nuclear power. Kim Jong Un wants better Abschreckung. This means he wants to scare his enemies. His sister Kim Yo Jong speaks for the country. She says: North Korea is an Atommacht. This is not open for talks. North Korea keeps its nuclear weapons.
The United Nations makes many punishments. These are called Sanktionen. The punishments stop the country. But North Korea builds rockets and nuclear weapons. The law says this is the goal since 2023. Many countries in the world are afraid.
