In the Henty Mance interview, Joseph Nye, who coined term 'soft power,' says that the turmoil facing the United States and Harvard was worse in the 1960s.

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. 

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

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.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

 This article argues and seeks to demonstrate that "global history," with its roots in the study of empires and transnational integration, provides a useful intellectual framework for better understanding the powerful forces currently reshaping the international system—most significantly geopolitical competition and economic decoupling between the United States and China in the age of Covid-19.

China has the world’s largest army. Russia wields the most tanks. America owns the fanciest satellites. But who has the most cyber-power? A new National Cyber Power Index by the Belfer Centre at Harvard University ranks 30 countries on their level of ambition and capability. Offensive cyber-power—the ability to do harm in or through computer networks—is one measure. But so too are the strength of a country’s defences, the sophistication of its cyber-security industry and its ability to spread and counter propaganda.

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.
