Nuclear Ethics Revisited

| Spring 2023

Scott Sagan asked Joseph S. Nye to revisit Nuclear Ethics, a book he published in 1986, in light of current developments in world affairs. In doing so, he found that much had changed but the basic usability paradox of nuclear deterrence remains the same.

Madman or Mad Genius? The International Benefits and Domestic Costs of the Madman Strategy

| 2023

According to the "Madman Theory" outlined by Daniel Ellsberg and Thomas C. Schelling, and embraced by Presidents Richard Nixon and Donald Trump, being perceived as mad can help make seemingly incredible threats—such as starting a nuclear war—more credible. However, recent research has largely concluded that the Madman Theory does not work.

| Spring 2023

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.

Why Biden and Yoon’s Agreement Is a Big Deal

| Apr. 27, 2023

The Washington Declaration signed by U.S. President Joe Biden and South Korean President Yoon Suk-yeol yesterday should be a ringing reminder of one of the greatest achievements of U.S. national security strategy: its decadeslong success in preventing the proliferation of nuclear weapons. The agreement strengthened nuclear deterrence coordination between the two allies and offered a greater sense of assurance that South Korea falls under the U.S. nuclear umbrella.

Mariana Budjeryn's Inheriting the Bomb tells the story of how Ukraine came into possession of the world's third-largest nuclear arsenal—larger than the combined stockpiles of China, France, and the United Kingdom at the time—and decided to disarm peacefully a few years later. Ukraine's denuclearization was far from a straightforward process. After initially renouncing nuclear weapons, Ukrainian officials sought recognition that their newly independent country was a rightful heir to part of the Soviet cache, deserving of equal treatment, financial compensation, and pledges that disarmament would not endanger Ukraine's security. 

The 2010 nuclear security summit in Washington, DC, was aimed at preventing nuclear terrorism.

Why Biden’s New Nuclear Security Agenda Might Not Work as Planned

| Apr. 04, 2023

Early in March, the Biden administration unveiled its 19th National Security Memorandum. While the operational part of this memorandum is classified, the White House shared a factsheet on the new strategy, which is centered around three main pillars: countering weapons of mass destruction terrorism, advancing nuclear material security, and improving radioactive material security. The three-pronged strategy aims to reinvigorate long-standing approaches to risks from weapons of mass destruction (WMD) and nuclear security and introduce new ways to deal with emerging threats.
