The North Korea Nuclear Crisis

How North Korea became a nuclear-armed state, the failure of diplomacy, and what options remain.

The Road to the Bomb

North Korea's nuclear ambitions date to the 1960s, driven by security concerns after the Korean War and the presence of US nuclear weapons in South Korea. With Soviet assistance, North Korea built a research reactor at Yongbyon in the 1980s.

The first nuclear crisis erupted in 1993-94, when North Korea threatened to withdraw from the NPT after the IAEA found discrepancies in its plutonium declarations. The Agreed Framework, negotiated by the Clinton administration, froze North Korea's plutonium program in exchange for heavy fuel oil and two light-water reactors. The deal collapsed in 2002 when the US accused North Korea of a secret uranium enrichment program, and North Korea withdrew from the NPT in 2003.

North Korea conducted its first nuclear test in 2006, followed by tests in 2009, 2013, 2016 (twice), and 2017. Its sixth test in 2017 was estimated at 100-370 kilotons — a thermonuclear weapon many times more powerful than Hiroshima. North Korea has also developed intercontinental ballistic missiles (ICBMs) that can reach the continental United States.
