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. 

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.

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.

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.

This article examines the trilateral relations between Russia, China, and Iran through their engagement in various issues from domestic, regional, and international levels. It explores the practices and coordination between Russia, China, and Iran in the international order, the Iranian Nuclear Program, the Shanghai Cooperation Organisation, domestic regime security, and economic connectivity. The article concludes that although Russia, China, and Iran have had overlapping interests and approaches in terms of contesting the Western created and dominated international "liberal" order, strengthening domestic regime security, defending authoritarian governance, and supporting de-dollarization, all of which have brought the three sides closer, a Russia–China-Iran axis has not thus far materialized. Rather, due to the lack of regularized and institutionalized mechanisms, the tripartite relationship remains an illusory entente, which is essentially driven by the bilateral ties followed by modest trilateral coordination in ad-hoc situations.

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 examines both the premise and prescription of the argument to integrate renewable electricity in developing countries through elements of the standard model (such as a wholesale spot market, or an independent system operator for dispatch). This is done by highlighting the differences between power sector reform experiences in the developing and developed worlds, and the causal mechanisms underlying these differences.

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.

In his new book, Do Morals Matter? Presidents and Foreign Policy from FDR to Trump, Joseph S. Nye developed a scorecard to determine how U.S. presidents since 1945 factored questions of ethics and morality into their foreign policy. In an interview, Henry Farrell asked him a few questions to get to the heart of his findings.
