Nuclear Issues

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Joseph Nye argues that official statements about India and America's "shared values" do not make an alliance. Following the basic logic of balance-of-power politics, India and the United States seem fated not for marriage but for a long-term partnership — one that might last only as long as both countries remain preoccupied with China.

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.

Grant Golub writes: For decades, Washington has called on U.S. allies to sustain greater shares of the defense burden while largely neglecting to take concrete actions to make this happen. This has helped allow other countries to become dependent on American military protection while letting their own defense capabilities atrophy.

Stephen Walt critiques Henry Kissinger's professional life by dividing it into three parts: as an academic at Harvard; as national security advisor and secretary of state; and as an author, pundit, and sage, much of it conducted as the head of Kissinger Associates, the consulting firm he founded after leaving government.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

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. 

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. 

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.

Joseph Nye considers U.S. options for risk reductions as nuclear threats escalate and China-Taiwan tensions rise.
