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

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.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

Unilateralism and isolationism are making a comeback in the United States. Are Trump and his America First approach to the world a cause or a symptom? What are the ideological sources of the intimate connection between isolationism and the American experience? Will the COVID-19 pandemic undercut or deepen globalization? What impact will it have on U.S. grand strategy? The United States seems headed for an inevitable pullback of its global commitments. What should retrenchment look like? Can Americans find the middle ground between doing too much and doing too little?

The geopolitical and geo-economic forces wrought by the coronavirus pandemic, as examined previously in this series, are likely to slow the transition to a more sustainable global energy mix. Fortunately, the pandemic has also resulted in governments gaining vastly greater influence over whether this shift stalls or accelerates.

For most people, there was nothing to celebrate when the International Monetary Fund downgraded its outlook for global economic growth in June, anticipating a contraction of 4.9% for 2020. Yet for others, such as the small but persistent group of economists and others known as the “degrowth movement,” the Covid-induced economic slowdown has a silver lining.

The search for silver linings to the coronavirus pandemic has come up woefully short. But one hopeful — and much talked of — prospect is that the disruption will accelerate the global shift to a more sustainable energy future.

For months, the coronavirus has crawled across the globe. One person at a time, it has passed through millions, reaching every corner of the earth. And it has not only infected people, but every aspect of our human cultures. Policymakers and the public sector face their biggest test in generations—some say ever—as lives and livelihoods hang in a terrible, delicate balance. Facing health crises, economic collapse, social and political disruption, we try to take stock of what the pandemic has done and will do. We asked Harvard Kennedy School faculty, in fields ranging from climate change to international development, from democracy to big power relations, to tell us how this epochal event has changed the world.
