Nuclear Issues

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

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

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

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.

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.

Stephen Walt asks whether the United States is a good model for other liberal states and whether its policy judgments are ones that others should trust and follow, especially with respect to foreign policy.  He argues that—on balance—the answer to both questions is "no."

Today, the origins of the concept of RW have largely been forgotten.  Indeed, since 9/11, radiological weapons have been associated mainly with non-state actors, who may not have the means or motivations to acquire and use far more lethal nuclear explosives.  A fixation on the very real dangers posed by nuclear terrorism, however, should not obscure the risks that states also may again pursue radiological weapons.

Stephan Walt writes that Trump's foreign-policy instincts might be more sound—but he has forfeited the chance to lead.
