Moreover, a tougher ROK administration might move in unpredictable directions. A popular majority has supported a South Korean nuclear deterrent for years, with seven in ten currently in favor. Further recognition of allied impotence would likely fuel South Korean support for building an ROK bomb.

The Biden administration should consider a significant change in emphasis, from denuclearization to arms control. Since the latter—such as capping the North’s program, reducing the size of its arsenal, imposing proliferation safeguards, forestalling development of some weapons, and more—would move the peninsula toward the former, Washington need not admit that it had abandoned comprehensive and verifiable denuclearization. However, this appears to be the only practical means to forestall or at least limit a nuclear arms race on the Korean Peninsula.

North Korea has oft been said to be the land of only bad options. That is ever more so as the North rapidly moves ahead with missile and nuclear development. With the promise of the Trump-Kim summits an increasingly distant memory, the Biden administration needs to find a new approach. And quickly.
