Leadership of Kim Jong Il

The Soviet Union was dissolved on 26 December 1991, ending its aid and support to North Korea. In 1992, as Kim Il Sung's health began deteriorating, his son Kim Jong Il slowly began taking over various state tasks. Kim Il Sung died of a heart attack in 1994; Kim Jong Il declared a three-year period of national mourning, afterward officially announcing his position as the new leader.

North Korea promised to halt its development of nuclear weapons under the Agreed Framework, negotiated with U.S. president Bill Clinton and signed in 1994. Building on Nordpolitik, South Korea began to engage with the North as part of its Sunshine Policy. Kim Jong Il instituted a policy called Songun, or "military first".

Flooding in the mid-1990s exacerbated the economic crisis, severely damaging crops and infrastructure and leading to widespread famine that the government proved incapable of curtailing, resulting in the deaths of between 240,000 and 420,000 people. In 1996, the government accepted UN food aid.

The international environment changed once George W. Bush became U.S. President in 2001. His administration rejected South Korea's Sunshine Policy and the Agreed Framework. Bush included North Korea in his axis of evil in his 2002 State of the Union Address. The U.S. government accordingly treated North Korea as a rogue state, while North Korea redoubled its efforts to acquire nuclear weapons. On 9 October 2006, North Korea announced it had conducted its first nuclear weapons test.

U.S. President Barack Obama adopted a policy of "strategic patience", resisting making deals with North Korea. Tensions with South Korea and the United States increased in 2010 with the sinking of the South Korean warship Cheonan and North Korea's shelling of Yeonpyeong Island.
