Asia & the Pacific

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.

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

Stephen Walt argues that Henry Kissinger's concerns about the destabilizing impact of ideas made him hypersensitive to the smallest perturbations in strategically marginal countries and inclined him to overreact to them in ways that other realists opposed.

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

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.

Stephen Walt writes that it may seem harder to give thanks this year, but it's not impossible. He enumerates five things for which to be grateful, including that none of the outside parties in the Middle East seem inclined to expand the conflict beyond Israel, Gaza, and the West Bank.

Among the many issues surrounding China’s ongoing military modernization, perhaps none has been more dramatic than its nuclear weapons program. For decades, the Chinese government was content to maintain a comparatively small nuclear force. As recently as 2020, China’s arsenal was little changed from previous decades and amounted to some 220 weapons, around five to six percent of either the U.S. or Russian stockpiles of deployed and reserve warheads.

“This is not a decision or set of steps that are happening in haste by any means, and this is a practice that is common and consistent around the world and with the nuclear energy industry,” said Marina Lorenzini of the Belfer Center for Science and International Affairs at the Harvard Kennedy School of Government.

According to data posted online by the Japanese Ministry of Economy, Trade and Industry, water with much higher levels of tritium has been discharged by nuclear facilities in countries including China, South Korea, Canada and France in line with local regulations.

Lorenzini said that the IAEA’s active engagement in the Fukushima process “makes me feel a lot more comfortable and confident with the events we see playing out today.”

The IAEA said this week that it would maintain an onsite presence at the Fukushima plant, where it opened an office last month, and publish real-time and near real-time monitoring data.

“I think we have good reason to believe that this will be a well-monitored and well-maintained operation,” Lorenzini said.

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.
