Addressing Russian and Chinese Cyber Threats: A Transatlantic Perspective on Threats to Ukraine and Beyond

| May 2023

In an interconnected world, cyberattacks are becoming more frequent and sophisticated. Building resilience against this asymmetric threat is critical for countries to protect their economies, critical infrastructure, and democratic institutions. However, cyberattacks do not respect borders, and no country can address this threat alone. The strength and longevity of the transatlantic partnership between the EU and the U.S. presents a unique opportunity to address this strategic threat through international cooperation. Through an analysis of cyberwarfare in the ongoing war in Ukraine, this paper proposes policy recommendations to enhance transatlantic coordination and cooperation against current and future adversaries in a new era of strategic competition. Ultimately, a stronger transatlantic partnership is critical for protecting international democratic norms, building resilience against cyber threats, and strengthening global security and stability.

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.

Guest Editors' Introduction: Nonviolent Resistance and Its Discontents

| 2023

In the past decade, myriad studies have explored the effects of nonviolent resistance (NR) on outcomes including revolutionary success (short-term and long-term) and democratization, and how nonviolent mobilization can play a similar role to violence in affecting social change in some settings. This special issue seeks to advance scholars' and policymakers' understanding of the role of nonviolence by tackling some key assumptions in existing work that are complicated by historical and contemporary realities of deepening polarization worldwide. This issue addresses four key areas within conflict and peace research that limit scholars' and policymakers' ability to make sense of NR: (a) the fragmented nature of civil resistance campaigns in terms of supporters and demands; (b) the increasing prevalence of authoritarian or anti-egalitarian nonviolent campaigns; and (c) the complicated nature of revolutionary success. Cutting across all three of these substantive areas is another key area, which is: (d) the United States as an increasingly salient site of conflict and contention.
