North Korea


Last Updated: August, 2019

North Korea (formally, the Democratic People's Republic of Korea or DPRK), has active and increasingly sophisticated nuclear weapons and ballistic missile programs, and is believed to possess chemical and biological weapons capabilities.

North Korea unilaterally withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in January 2003, is not a party to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), and has conducted six increasingly sophisticated nuclear tests since 2006. The DPRK is not a party to the Chemical Weapons Convention (CWC), and is believed to possess a large chemical weapons program. Despite being a state party to the Biological and Toxin Weapons Convention (BTWC) and Geneva Protocol, evidence suggests North Korea may maintain an offensive biological weapons program.

In defiance of the international community, which has imposed heavy sanctions on North Korea for its illicit behavior, the country has continued to escalate its WMD activities. In July 2017, North Korea successfully tested its first intercontinental ballistic missile (ICBM), and in September 2017 it conducted a test of what it claimed was a thermonuclear weapon. [1]

After years of heightened regional tensions and frequent North Korean nuclear and ballistic missile tests, early 2018 saw a thaw in diplomatic relations. In April, North Korean leader Kim Jong-un announced a halt to all nuclear and ICBM tests, and participated in a summit meeting with the leader of South Korea. [2] On 12 June 2018, Kim met with U.S. President Donald Trump in Singapore, the first face-to-face meeting between leaders of North Korea and the United States in history. At the summit, the DPRK pledged “to work toward complete denuclearization of the Korean Peninsula.” [3]

The second summit between the two leaders, held from 27-28 February 2019 in Hanoi, Vietnam, did not yield an agreement between the two countries nor any substantive progress toward denuclearization. [4] A post-summit stall in diplomatic talks was punctuated by North Korea's resumption of short-range ballistic missile tests in May 2019, the first such tests in over 18 months. [5] These were followed by a series of SRBM tests in July and August 2019.

North Korea’s nuclear ambitions date to the Korean War in the 1950s, but came to the attention of the international community in 1992, when the International Atomic Energy Agency (IAEA) discovered that its nuclear activities were more extensive than declared. [6] The revelations led North Korea to withdraw from the IAEA in 1994. In an effort to prevent North Korean withdrawal from the NPT, the United States and North Korea negotiated the Agreed Framework, in which Pyongyang agreed to freeze its nuclear activities and give access to IAEA inspectors in exchange for U.S.-supplied light water reactors and energy assistance. [7] The Agreed Framework broke down in 2002. [8] North Korea unilaterally withdrew from the NPT in January 2003, prompting China, Japan, Russia, South Korea, and the United States to engage North Korea in the Six-Party Talks in a further attempt at a diplomatic solution to the country’s nuclear program. The talks fell apart in 2009, and no serious diplomatic initiatives to denuclearize North Korea occurred until 2018. [9] At the June 2018 U.S.-North Korean summit, Kim Jong-un “reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean Peninsula,” although North Korea’s definition of “denuclearization” is ambiguous. [10] No agreement on a method or timetable for dismantling North Korea’s nuclear weapons has been reached. [11]

North Korea produces both weapons-useable plutonium and enriched uranium, with one U.S. government estimate in 2017 suggesting the country may be producing enough nuclear material each year for 12 additional nuclear weapons. [12]


North Korea signed the Geneva Protocol and acceded to the Biological and Toxin Weapons Convention (BTWC) in 1987. U.S. intelligence sources consider North Korea capable of biological weapons production and weaponization. [13] However, open source information on the status of the DPRK's biological weapons program varies. The 2016 Defense White Paper by South Korea's Ministry of National Defense estimates that the DPRK possesses the causative agents of anthrax and smallpox, among others. [14] The U.S. Secretary of Defense’s 2015 report assesses that North Korea may consider the use of biological weapons as an option, contrary to its obligations under the Biological and Toxins Weapons Convention (BTWC), but does not reference specific agent stockpiles. [15]


North Korea is not a signatory to the Chemical Weapons Convention (CWC). [16] The DPRK’s pursuit of chemical weapons dates to 1954, and it most likely obtained indigenous offensive CW production capabilities in the early 1980s. [17] A South Korean 2016 Defense White Paper estimates that North Korea has stockpiled between 2,500 and 5,000 tons of CW agent. [18]

Pyongyang has concentrated on acquiring mustard, phosgene, sarin, and V-type chemical agents. Reports indicate that the DPRK has approximately 12 facilities where raw chemicals, precursors, and agents are produced and/or stored, as well as six major storage depots for chemical weapons. [19] The United Nations Human Rights Council reported that North Korea may have tested chemical weapons on prisoners and the disabled in February 2014, though it could not independently confirm the accuracy of defector accounts. [20] In February 2017, the half-brother of North Korean leader Kim Jong-un, Kim Jong-nam, was assassinated in the Kuala Lumpur international airport. Following the attack, Malaysian officials announced that Kim Jong-nam was killed by suspected North Korean agents wielding the nerve agent VX. [21]


North Korea possesses a large and increasingly sophisticated ballistic missile program, and conducts frequent missile test launches, heightening East Asian tensions. In 2017, North Korea successfully tested the Hwasong-14 and Hwasong-15, its first ICBMs, which some experts believe gives North Korea the capability to deliver a nuclear payload anywhere in the United States. [22]

North Korea’s initiated its ballistic missile program in the late 1970s and early 1980s, when it acquired Soviet Scud-type missiles from Egypt and reverse-engineered them. [23] In the early 1990’s, with assistance from Iran and several other countries, North Korea began producing Nodong medium-range ballistic missiles (MRBM). [24] North Korea has developed and tested a number of new missiles since Kim Jong-un’s ascension to leadership in 2011, such as the Intermediate-Range Hwasong-12 and the extended range (ER) Scud. [25] In May 2019, North Korea began a series of tests of the KN-23, a road-mobile solid-fueled short-range ballistic missile which resembles the Russian Iskander-M. [26]

In addition to its land-based ballistic missiles, North Korea has successfully tested a submarine-launched ballistic missile, the Pukguksong-1. [27] North Korea also has a Space Launch Vehicle, the Unha, which uses technologies closely related to its ballistic missiles. [28] North Korea is not a member of the Missile Technology Control Regime (MTCR).
