In which year did North Korea test nuclear weapons for the first time in its history?

North Korea is a country in East Asia constituting the northern part of the Korean Peninsula, with Pyongyang as its capital and the largest city in the country. The U.S. government treated North Korea as a rogue state, while North Korea redoubled its efforts to acquire nuclear weapons to avoid the fate of Iraq. On 9 October 2006, North Korea announced it had conducted its first nuclear weapons test. In the face of international condemnation, North Korea continued to develop its nuclear arsenal, possibly including a hydrogen bomb and a missile capable of reaching the United States.
