North Korea’s Nuclear Arsenal and Prospects for Regional Peace

This article was originally published by The Rand Blog.

Nuclear talks between the United States and North Korea have hovered at a standstill since 2019, when then-President Donald Trump and Kim Jong-un walked away from the negotiating table in Hanoi with a “no-deal.” To date, there has been no contact between negotiators in Washington and Pyongyang aimed at resuscitating talks over the Kim regime’s nuclear weapons program. And to the consternation of U.S. officials, Pyongyang has continued expanding its suite of missile delivery capabilities and appears to have restarted operations at its main nuclear facility, Yongbyon (PDF), to produce plutonium to build nuclear weapons. The Democratic People’s Republic of Korea (DPRK) continues to accuse the United States of pursuing a hostile policy towards the Kim regime and even warned Washington of a response that could leave the country in a very grave situation.

This surely sounds foreboding. With the door to diplomacy seemingly closed and North Korea marching forward on weapons development and making threatening statements, what are the prospects for Pyongyang’s denuclearization and peace on the Korean Peninsula?

Pyongyang’s Nuclearization and Disinterest in Peace

Nuclear weapons are here to stay in North Korea. Earlier this year, Kim underscored the primacy of the DPRK’s nuclear weapons program for the country’s existence by describing it as its “strategic and predominant goal (PDF) in building our ideal powerful socialist state.” He also announced plans to further develop “ultra-modern tactical nuclear weapons,” including tactical rockets and ballistic missiles. True to its leader’s word, Pyongyang demonstrated an array of new missile capabilities, including a hypersonic missile capable of carrying a nuclear warhead, a submarine-launched ballistic missile, and a cruise missile.

These developments reinforce North Korea’s unbending position on preserving its nuclear weapons program, reflected in Kim’s bottom-line offer to Trump at the Hanoi summit—shutting down fissile material production facilities at Yongbyon in exchange for Washington’s sanctions relief. Not only would this have allowed Pyongyang to keep its nuclear weapons systems and facilities, the revenue generated from sanctions relief would have likely been funneled back into beefing up the very weapons programs the United States, South Korea, and the international community are trying to stop. Prospects for the Kim regime’s denuclearization, therefore, are faint at best.

North Korea’s intransigence on its nuclear weapons program has implications for the peace process on the Korean Peninsula. Kim’s determination to use these weapons to endanger the security of its most proximate neighbor, South Korea, as well as the stability of the region and U.S. interests, jeopardizes progress for peace and tension-reduction with Washington, Seoul, and the international community. In addition to its nuclear and missile threats, the DPRK also resorts to conventional military provocations to pressure its neighbors.

Pyongyang’s June 2020 demolition of the inter-Korean liaison office—a symbol of the development of inter-Korean cooperation and peace settlement—dashed Seoul’s hopes of fostering inter-Korean cooperation. The DPRK has also violated the Inter-Korean Comprehensive Military Agreement on several occasions, including conducting artillery drills near the Northern Limit Line and firing gunshots at a South Korean guard post in the demilitarized zone. The DPRK, therefore, appears to not only resist efforts to improve relations with Seoul; in fact, it appears to go the extra mile to convey the message to the international community that it has little appetite for a peace process.
