In a significant diplomatic development, the second U.S.-Republic of Korea (ROK) Nuclear Consultative Group (NCG) meeting took place in Washington D.C. on December 15, 2023. Established under the framework of the Washington Declaration between President Biden and President Yoon Suk Yeol, the NCG aims to fortify the U.S.-ROK Alliance and enhance extended deterrence in the region.

Key Highlights:

- U.S. commitment to provide extended deterrence to the ROK, including nuclear capabilities.

- Clear stance: Any nuclear attack by North Korea against the U.S. or its allies is deemed unacceptable, promising severe consequences for the Kim regime.

- Deepened cooperation: Both nations acknowledged progress in nuclear deterrence cooperation through NCG working groups, covering various aspects such as guidelines, security protocols, nuclear consultation processes, strategic planning, and risk reduction practices.

- Notable achievements: The meeting highlighted strategic assets' enhanced visibility, demonstrated through significant events like the USS KENTUCKY ballistic missile submarine port visit, B-52 bomber flyover, and a joint observation of an ICBM test launch.

- Forward-looking plans: Principals approved a work plan for the first half of 2024, emphasizing substantive progress and swift action. Future plans include the third principal-level NCG meeting in Korea next summer.

This collaborative effort underscores the shared commitment of the U.S. and South Korea to maintaining peace and stability on the Korean Peninsula through robust deterrence measures. The NCG meetings serve as a crucial platform for strategic coordination and planning between the two nations.
