"The declaration moves beyond what could be characterized as nuclear sharing … to address the more fundamental goal of developing a joint approach to military planning for, and operating in, nuclear contingencies, including through new exercises and simulations to improve operational readiness," the unnamed official said.
The remarks feed into the debate triggered after the South Korean President’s state visit to the US, where Yoon Suk-yeol had been met with much pomp to commemorate the 17th anniversary of the two countries’ security alliance. Ahead of the visit, there had been speculations as to what manner of upgrade, so to say, might be offered for the reinforced US-ROK alliance, especially under the pretext of North Korea’s (DPRK) schedule of missile simulations and test firings.The most important outcome of the visit was the signing by the South Korean President and his US counterpart, Joe Biden, of the Washington Declaration. The deal provides for the establishment of a regular bilateral consultation mechanism called the US-South Korean Nuclear Consultative Group on extended deterrence and strategic planning. The Republic of Korea (ROK) also secured a US promise to promptly deploy “the entire force of the alliance,” including nuclear weapons, in the event of a nuclear attack by North Korea. The US also promised to send nuclear missile submarines to the Korean Peninsula. Seoul, meanwhile, reaffirmed its nonproliferation obligations under the Nuclear Non-Proliferation Treaty (NPT).It should be clarified that “nuclear sharing” is a NATO deterrence concept, allowing member countries without nuclear weapons of their own to participate in planning for the use of nuclear weapons by the alliance. South Korea is not a NATO member. However, interpretation of the term had opened up a debate in the wake of Yoon Suk-yeol’s Washington foray. ROK’s deputy national security adviser, Kim Tae-hyo, had openly enthused:”Going forward, our citizens will de facto feel as if we are sharing nuclear weapons with the US.”But a Biden administration official was quick to wade in with clarifications. Edgard Kagan, special assistant to the president and senior director for East Asia and Oceania of the National Security Council (NSC), said that the Washington Declaration was not a “nuclear-sharing” arrangement. He said the declaration emphasized America’s commitment to consult with South Korea on any possible nuclear weapons employment on the Korean Peninsula. “So let me just be very direct. I don’t think that we see this as a de facto nuclear sharing,” said Kagan.
