International Security & Defense

This week in Say More, Project Syndicate talks with Joseph S. Nye, Jr., an emeritus professor at Harvard Kennedy School, a former U.S. assistant secretary of defense, and the author, most recently, of A Life in the American Century.

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. 

Stephen Walt argues that if the world is entering a period of defense dominance—and if the resolve of most states is greatest in their immediate surroundings—then the ability of any country to wield vast and unchallenged global influence will decline. In such a world, the United States will have to pick its battles more carefully than it has in the past.

In this deeply personal book, Joseph Nye shares his own journey living through the American century.

Stephen Walt analyses the past thirty years of U.S. foreign policy toward the Middle East, focusing on five events.

Dominant normative theories of civil-military relations focus on ideal-type scenarios that do not reflect the messy, inherently political character of elite decision-making. A case study of civil-military dynamics during the Iraq War identifies four decision-making strategies that George W. Bush and Barack Obama used to avoid incurring a domestic political penalty for rejecting the military’s preferences.

Around the world, the United States relies heavily on security assistance to gain influence and make its allies more formidable. When actual war breaks out, however, many long-time recipients of such assistance fight poorly or otherwise do not seem to have heeded the lessons that U.S. trainers tried to impart. The Naval War College’s Rachel Tecott Metz examines this track record, arguing that the United States relies too much on teaching and persuasion and should instead emphasize conditionality more. 

The lessons from our wartime folly are stark, but we should learn them.

Stephen Walt argues that in a multipolar world, the United States will be in an ideal situation to play the other major powers off against each other, and it can let its partners in Eurasia bear more of the burden of their own security. 

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.
