Recent ballistic missile tests and military parades suggest that North Korea is continuing to build a nuclear warfighting capability designed to evade regional ballistic missile defenses. Such an approach likely reinforces a deterrence and coercive diplomacy strategy-lending more credibility as it demonstrates capability-but it also raises questions about crisis stability and escalation control. U.S. policy as well as U.N. resolutions call on North Korea to abandon its nuclear weapons and missile programs. Kim Jong Un has repeatedly rejected denuclearization talks. According to the U.S. intelligence community's 2023 annual threat assessment (ATA), North Korean leader Kim Jong-un views nuclear weapons and intercontinental ballistic missiles (ICBMs) as the ultimate guarantor of his autocratic rule and has no intention of abandoning those programs, believing that over time he will gain international acceptance as a nuclear power. The Korea People's Assembly adopted a new law in September 2022 that reportedly expands the conditions under which North Korea would use nuclear weapons to include possible first use in situations that threaten the regime's survival. In response to these developments, the United States and South Korea have conducted joint military drills and revived the bilateral Extended Deterrence Strategy and Consultation Group. The Biden Administration's 2022 Nuclear Posture Review said, Any nuclear attack by North Korea against the United States or its Allies and partners is unacceptable and will result in the end of that regime. Congress may choose to examine U.S. policy toward North Korea. Nuc'ar Testng North Korea has tested a nuclear explosive device six times since 2006. Each test produced underground blasts progressively higher in magnitude and estimated yield. North Korea conducted its most recent test on September 3, 2017. A North Korean press release stated it had tested a hydrogen bomb (or two-stage thermonuclear warhead) that it was perfecting for delivery on an intercontinental ballistic missile. In April 2018, North Korea announced that it had achieved its goals, would no longer conduct nuclear tests, and would close down its Punggye-ri nuclear test site. It dynamited the entrances to two test tunnels in May 2018. International Atomic Energy Agency (IAEA) reports say North Korea began restoring test tunnels in March 2022 and the test site remains prepared to support a nuclear test. Nuclear Material Production North Korea reportedly continues to produce fissile material (plutonium and highly enriched uranium) for weapons. North Korea restarted its plutonium production facilities after it withdrew from a nuclear agreement in 2009, and is operating centrifuge uranium enrichment plants at the Yongbyon nuclear complex and possibly at Kangson. In March 2023, the IAEA reported construction and operations at the Yongbyon uranium centrifuge enrichment plant, Radiochemical Laboratory plant and Experimental Light Water 5MW(e) Reactor. Spent fuel from that reactor is reprocessed at the Radiochemical Laboratory to extract plutonium for weapons. In September 2022, the IAEA reported ongoing uranium mining, milling, and concentration activities at Pyongsan. Fissile material production in large part determines the number and type of nuclear warheads a country is able to build. Nucdear Warheads Outside experts estimate that North Korea has produced enough fissile material for between 20 to 60 warheads. A 2021 U.S. Defense Intelligence Agency (DIA) report says that North Korea retains a stockpile of nuclear weapons. Another goal of a nuclear weapons program is to lower the size and weight of a nuclear warhead for deployment on missiles. A July 2017 DIA assessment and some outside observers asserted North Korea had achieved the level of miniaturization required to fit a nuclear device on weapons ranging from short-range ballistic missiles (SRBM) to intercontinental ballistic missiles (ICBM). Kim Jong-un in January 2021 said that the country was able to miniaturize, lighten and standardize nuclear weapons and to make them tactical ones. In his January 1, 2023 speech, Kim said the country would exponentially expand its nuclear arsenal and mass produce tactical nuclear weapons. Missile Testing North Korea has conducted over 80 ballistic missile test launches since 2022, according to U.S. government officials. U.N. Security Council (UNSC) resolutions prohibit North Korea's development of the means of delivering conventional and nuclear payloads, in addition to the nuclear weapons themselves. UNSC resolutions specifically ban all ballistic missile tests by North Korea. A ballistic missile is a projectile powered by a rocket engine until it reaches the apogee of its trajectory, at which point it falls back to earth using earth's gravity. Ballistic missiles can deliver nuclear and large conventional payloads at high speed and over great distances. They are categorized as short-range, medium-range, or long-range (intercontinental) based on the distance from the launch site to the target. North Korea is developing delivery systems that possess certain critical features: mobility, reliability, potency, precision, and survivability. Mobile weapons have
