Nuclear Issues

Assaf Zoran examines the dynamics of Iran's shift from operating in the shadows or behind partners and proxies to directly attacking Israel and Pakistan.

Stephen Walt explains why Putin understood that Ukraine's fate was more important to Russia than it was to the West.

Abolghasem Bayyenat argues that without the JCPOA restrictions in place, Iran's nuclear program will expand and continue to acquire irreversible technical knowledge and competencies.

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.

Russia's war in Ukraine has brought questions of nuclear deterrence back to the fore, reminding world leaders that risk reduction must remain a top item on the global agenda. Because political and technological change will always introduce new issues, the work of maintaining a "just deterrence" is never done.
