The purpose of this paper is to analyse the threats and actions of the North Korean government, which is challenging international peace and order with nuclear explosive tests and intercontinental ballistic missile tests that are of particular concern to the United States due to its recent direct threats to the island of Guam. Critical events throughout history from 1953 to date and sanctions imposed by international bodies such as the UN and inspections by the IAEA (International Atomic Energy Agency) will be analysed. This is why we point out in this essay that North Korea, by defying UN Resolutions, defies the whole world. The reasons for the North Korean government's actions will be discussed in this paper.
