Nuclear Issues

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

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.

Juliette Kayyem writes that deliberately accepting some risks, and then being prepared when disaster strikes, will serve human societies better than pretending that perfect safety is achievable. We cannot prevent an earthquake or a tsunami, but we have control over how much death and destruction it causes.

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.

The probability of terrorists getting and using a nuclear bomb appears to be low—but the consequences if they did would be so devastating that it is worth beefing up efforts to make sure terrorists never get their hands on a nuclear bomb’s essential ingredients. To see the possibilities, we need to look at motive, capability, and opportunity.

Proponents of “transactional” diplomacy argue that comprehensive deals to transform political relationships are unrealistic, and that zeroing in on the most pressing issue is the only way to make any tangible progress. The “grand bargainers” retort that any deal that isn’t comprehensive will face fatal opposition from important stakeholders.

Both arguments have some merit, but the perceived distinction between them is a false one: Past engagements with Iran and North Korea were premised on the hope that piecemeal transactions could provide a platform for more sweeping diplomacy. And the best nonproliferation progress has been achieved when all sides perceived diplomatic transactions as incremental steps toward broader reconciliation.

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

Jayita Sarkar explains why the Biden administration needs to re-conceptualize nuclear terrorism and act quickly.

Every president serving in the last two decades has said that nuclear terrorism is a significant national security threat. Analysis of this threat has been, for good reason, mostly focused on foreign extremist groups, but recent events raise questions of whether there should be greater focus in the United States on far-right, domestic extremist threats. These extremists represent a unique danger because of their prevalence in federal institutions such as the military and the potential that they might infiltrate nuclear facilities, where they could access sensitive information and nuclear materials.

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.
