Although China's motives for developing the Belt and Road Initiative (BRI) have been well studied, scholars have yet to comprehensively examine why states seek to join the initiative. The authors fill this gap by examining how and why states join the BRI. Countries join by signing a Memorandum of Understanding (MOU) with China on cooperation under the BRI framework.

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.

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. 

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.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

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.

Two variables help determine whether ideological enemies are likely to ally against a shared material threat. States’ susceptibility to domestic ideological changes and the nature of states’ ideological differences are two contending forces that influence alliance formation or failure.

Former President Bill Clinton reflected on the foreign policy challenges of his presidency at the inaugural Stephen W. Bosworth Memorial Lecture in Diplomacy, hosted Wednesday by the Harvard Kennedy School.

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