75 Years On, How Will The Nuclear Age End?

Seventy-five years ago, U.S. nuclear weapons devastated Hiroshima and Nagasaki. For individual human beings, 75 years signals nearness to the end of life. But for the nuclear age, does this anniversary mark the beginning, the middle, or the end?

Nuclear Policy

The Nuclear Policy Program aims to reduce the risk of nuclear war. Our experts diagnose acute risks stemming from technical and geopolitical developments, generate pragmatic solutions, and use our global network to advance risk-reduction policies. Our work covers deterrence, disarmament, arms control, nonproliferation, and nuclear energy.

Seventy-five years ago, U.S. nuclear weapons devastated Hiroshima and Nagasaki. For individual human beings, 75 years signals nearness to the end of life. But for the nuclear age, does this anniversary mark the beginning, the middle, or the end?

There are two dramatic ways in which the nuclear age could end: annihilation or disarmament. If one ending is undesirable and the other unachievable, leaders should prolong life with nuclear weapons by making their use much less likely and reducing their destructiveness in case they are used. Clearer adherence to the law of armed conflict and greater understanding of the climatic effects of nuclear war would serve both purposes.

Annihilation could come through war involving arsenals that devastated not only the societies of the belligerent countries, but also the agricultural productivity and economic markets on which many other nations depend. Some nations would survive, and some could retain nuclear weapons or ambitions to acquire them, but for the purposes of marking epochs, we could say that the first nuclear age would have ended.

Nuclear disarmament is a much happier prospect. This is one reason that many in Japan and other countries advocate it and support the 2017 Treaty on the Prohibition of Nuclear Weapons. However, the treaty does not detail how nuclear disarmament would be defined, achieved over time, verified, and enforced. Nor have the nine nuclear-armed states done so, even though the Nuclear Non-Proliferation Treaty obligates the United States, Russia, the United Kingdom, France, and China “to pursue negotiations in good faith on effective measures” to end the nuclear arms race and achieve nuclear disarmament. (The Lawrence Livermore National Laboratory’s Center for Global Security Research just published a monograph by Toby Dalton and me that maps quandaries a disarmament regime would need to solve, “Thinking the Other Unthinkable: Disarmament in North Korea and Beyond.”)

    Negotiating an Age of Conquest: Converting American Power Into Durable Political Outcomes

    There is a deeply rooted assumption in post–Cold War American statecraft that overwhelming military and economic power translates directly into favorable political outcomes. But force alone is rarely enough. To meet the challenges of the mid-21st century, Washington needs a cultural shift toward a mindset that takes negotiation far more seriously.
