Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

At a moment when arms control is deeply troubled and may be dying, two eminent scholars, Marc Trachtenberg and the late Robert Jervis, have taken a fresh look at the beginnings of strategic arms control fifty years after the signing in Moscow of the SALT I agreements in May of 1972. They do so from different vantage points, writes Steven E. Miller.

Peaking great powers facing a slowdown in growth are likely to try to violently shake up the world. These findings amend classic theories of great power conflict. They help explain some of the most consequential geopolitical events in modern history. And they have ominous implications for contemporary Chinese foreign policy. 

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. 

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.

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.

Days before the midterms, The Harvard Crimson sat down with three scholars for a conversation about U.S. democracy. The mood was anxious.

Ernest May Fellow in History & Policy Grant H. Golub discussed the World War II–era expansion of the now-defunct U.S. Department of War during a virtual International Security Program seminar on October 13, 2022.

As diplomats, activists, and researchers converged on Vienna in June for the first meeting of states-parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW), recent tragic world events highlighted how critical it was to convene this multilateral forum on nuclear disarmament.

Since February, Russia’s war against Ukraine has epitomized the grave dangers of a world where nine states possess approximately 12,700 nuclear weapons.¹ That Russia could invade a sovereign state and indiscriminately target its civilian population, while using nuclear threats to deter NATO from intervening, has stunned the world. It offers a stark reminder that possessing nuclear arms can enable abhorrent violations of international law

Hostile foreign states are using weaponized information to attack the United States. Russia and China are disseminating disinformation about domestic U.S. race relations and COVID-19 to undermine and discredit the U.S. government. These information warfare attacks, which threaten U.S. national security, may seem new, but they are not. Using an applied history methodology and a wealth of previously classified archival records, this article uses two case studies to reveal how and why a hostile foreign state, the Soviet Union, targeted America with similar disinformation in the past
