South Korea faces a complex security dilemma, grappling with the specter of North Korean aggression and a rapidly evolving geopolitical landscape. With an increasing sense of vulnerability amidst North Korea’s nuclear provocations , a significant portion of the South Korean public has shown support for the nation to acquire its own nuclear weapons. Surveys reflect that over 70% of South Koreans favor the development or redeployment of nuclear arms on the peninsula, a stark uptick in pro-nuclear sentiment since the withdrawal of American nuclear weapons in 1991.
This notion of nuclear armament has found its way into the mainstream of South Korea’s national security discourse. The public’s desire for a nuclear deterrent is born out of a fear of North Korean nuclear threats and doubts about the continued reliability of the U.S. to extend its nuclear umbrella in the face of its own security challenges. In 2023, South Korean President Yoon Seok-yeol publicly expressed these concerns, acknowledging for the first time the possibility of redeploying U.S. tactical nuclear weapons or launching indigenous development.
However, experts and analysts caution that the pursuit of nuclear weapons by South Korea could destabilize regional security and be counterproductive to the nation’s interests. The ROK already has the conventional capabilities needed to strike any target in North Korea through the use of short-range ballistic missiles and precision strike weapons, has recently committed $81 billion toward strengthening its pre-existing defense capabilities. Furthermore, South Korea is shielded by the United States’ reaffirmed commitment to extended deterrence as evidenced by the Washington Declaration and the updated Tailored Deterrence Strategy agreement between the two allies.
The political, military, and economic ramifications of South Korea’s potential nuclearization are considerable. As an active participant in international non-proliferation agreements, South Korea risks undermining its moral stance against North Korea’s nuclear activities, as well as damaging its standing in the international community and straining its primary alliance with the United States.
