China bans seafood from Japan after Fukushima nuclear plant begins releasing wastewater

| Aug. 24, 2023

“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.

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.

Then What? Assessing the Military Implications of Chinese Control of Taiwan

| Summer 2022

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

The Nuclear Balance Is What States Make of It

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

Defending the United States: Revisiting National Missile Defense against North Korea

| Winter 2021/22

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Caught Red-Handed: How States Wield Proof to Coerce Wrongdoers

| Fall 2021

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.

Winning and Losing the Nuclear Peace: The Rise, Demise, and Revival of Arms Control

| January/February 2022

Michael Krepon’s book Winning and Losing the Nuclear Peace: The Rise, Demise, and Revival of Arms Control comes at the perfect time. On the one hand, 2021 was a relative boon for arms control compared to the past five years. In January, U.S. President Joe Biden and Russian President Vladimir Putin agreed to extend the 2010 New Strategic Arms Reduction Treaty (New START) for five years. Following a summit in June, they also committed to hold strategic stability dialogues to “lay the groundwork for future arms control and risk reduction measures.” On the other hand, the past 20 years have seen a steady erosion of arms control agreements due to Russian violations and U.S. withdrawals. This trajectory raises questions about how this era should be viewed in the context of arms control history and how arms control could contribute to future security. Enter Krepon, who provides both a comprehensive historical narrative and a call to action.

Japanese Public Opinion, Political Persuasion, and the Treaty on the Prohibition of Nuclear Weapons

| 2020

The Treaty on the Prohibition of Nuclear Weapons (TPNW) poses a challenge to decades of Japanese nuclear policy. While Japan has relied on the US nuclear umbrella since the aftermath of World War II, numerous pro-disarmament groups — including the Hibakusha — are calling for Tokyo to join the Treaty. The authors contribute to these discussions with commentary on a new national survey they conducted in Japan (N = 1,333). Their results indicate that baseline support for the Prime Minister signing and the Diet ratifying the TPNW stands at approximately 75% of the Japanese public.
