Nuclear Issues

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

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.

What sounded so simple during last year’s presidential campaign has turned out, like everything related to Iran, to be quite complicated.

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

The move of President Donald Trump to visit Baghdad on Wednesday is a small, good one, amid a week of calamitous decisions. The press will understandably highlight the time that Trump spends with U.S. troops. Yet a key objective of the trip will have been to shore up the new Iraqi government's confidence in the U.S., as Iraqi officials must be high on the list of those shocked by the president’s recent decisions to rapidly withdraw U.S. forces from Syria and Afghanistan. Perhaps the president has realized that his administration has some hard work to do if there is any hope of keeping his latest determinations from dramatically strengthening Iran.
