Matthew Evangelista examines the precedents and possibilities for postwar European security in an interview with International Security Executive Editor Jacqueline L. Hazelton.

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.

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.

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. 

There seems to exist a general consensus on how to conceptualize cooperation in the field of international relations (IR). The authors argue that this impression is deceptive. In practice, scholars working on the causes of international cooperation have come to implicitly employ various understandings of what cooperation is. Yet, an explicit debate about the discipline's conceptual foundations never materialized, and whatever discussion occurred did so only latently and without much dialog across theoretical traditions. In this article, the authors develop an updated conceptual framework by exploring the nature of these differing understandings and situating them within broader theoretical conversations about the role of cooperation in IR.

With rational decision-making, the likelihood of strategic nuclear exchange should be zero. But emotions can create uncertainty, contradicting the expectations of the rational cost-benefit assumptions undergirding deterrence theory.

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.

A new theory of war duration suggests that strategic narratives explain why the U.S. war in Afghanistan endured and ended. A robust anti-terrorism narrative generated audience costs for presidential inaction. As the narrative weakened, these costs declined, and the war ended.
