Nuclear Issues

Calder Walton writes that Soviet espionage inside the Manhattan Project would change history. By the end of World War II, Stalin's spies had delivered the secrets of the atomic bomb to the Kremlin. This accelerated Moscow's bomb project. When the Soviets detonated their first atomic weapon in August 1949, it was a replica of the weapon built at Los Alamos and dropped by the Americans on Nagasaki.

Joseph Nye argues that official statements about India and America's "shared values" do not make an alliance. Following the basic logic of balance-of-power politics, India and the United States seem fated not for marriage but for a long-term partnership — one that might last only as long as both countries remain preoccupied with China.

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. 

Joseph Nye considers U.S. options for risk reductions as nuclear threats escalate and China-Taiwan tensions rise.

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

Joseph Nye writes that Russian aggression and nuclear saber rattling have reminded us that the likelihood of nuclear war is a matter of both independent and interdependent probabilities. Paradoxically, reducing the probability of an all-out catastrophe requires that we learn to accept a certain degree of risk and uncertainty.

Joseph Nye posits that the real lesson from Russia's war in Ukraine is that the international community must reinforce the existing NPT and refrain from actions that erode it.

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

Stephen Walt argues that the ultimate goal should be conflict resolution in Ukraine—not just an end to the fighting but a political arrangement that makes a resumption of war later on less likely.

Stephen Walt offers a tentative and far-from-comprehensive survey of what scholars have to say about the war in Ukraine.
