Nuclear Issues

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Joseph S. Nye writes that evaluating ethics in international relations is difficult, and Kissinger's legacy is particularly complex. Over his long tenure in government, he had many great successes, including with China and the Soviet Union and the Middle East. Kissinger also had major failures, including in how the Vietnam War ended. But on net, his legacy is positive. In a world haunted by the specter of nuclear war, his decisions made the international order more stable and safer.

As the Biden administration and Congress struggle to get their heads around the challenge posed by China today, they should reflect on lessons learned in America’s success in winning the Cold War with the Soviet Union. Just because fundamental and irresolvable differences in values and interests compel the United States and China to be formidable rivals does not mean a hot war is a viable option.

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

For the United States, the dominant approach has been economic coercion. Despite applying stringent sanctions, the United States has been ineffective in convincing North Korea to give up its nuclear arsenal in return for a brighter economic and diplomatic future. The myriad U.S. sanctions have also failed to halt major progress in North Korea’s nuclear and missile programs. However, these setbacks have not caused the United States to change its strategy of economic coercion. On the contrary, the United States has considerably increased its use of this economic statecraft tool. In contrast, China has deepened its economic engagement with the North Korean regime since the late 2000s. Through the relationship between the Chinese Communist Party and its counterpart the Workers’ Party of Korea, China has cultivated and monetized political ties. Doing so has provided a powerful mechanism through which the Kim family regime—leaders of North Korea’s ruling and prosperous 1 percent—has shored up stability and thrived.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Proponents of “transactional” diplomacy argue that comprehensive deals to transform political relationships are unrealistic, and that zeroing in on the most pressing issue is the only way to make any tangible progress. The “grand bargainers” retort that any deal that isn’t comprehensive will face fatal opposition from important stakeholders.

Both arguments have some merit, but the perceived distinction between them is a false one: Past engagements with Iran and North Korea were premised on the hope that piecemeal transactions could provide a platform for more sweeping diplomacy. And the best nonproliferation progress has been achieved when all sides perceived diplomatic transactions as incremental steps toward broader reconciliation.

Trump tied American jobs to endless wars in the Middle East. Biden should link them to renewed diplomacy.
