Recent scholarship on nuclear proliferation finds that many forms of nuclear assistance increase the odds that recipient states pursue nuclear weapons programs. While these studies may help us understand select cases of proliferation, they overshadow the role of nuclear supply in bolstering global nonproliferation efforts. After the risks of nuclear assistance became well-known following India’s nuclear explosion in 1974, most major suppliers conditioned their assistance on recipients joining nonproliferation agreements. Case studies of states’ decision-making regarding these agreements illustrate how the provision of nuclear technology has been an effective tool in persuading states to join such agreements, the most important of which is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). By joining the NPT, states strengthen the global nonproliferation regime and increase the costs of any potential future decision to proliferate. The offer of nuclear assistance has done far more to bolster global nuclear nonproliferation efforts than recent research suggests.

This paper argues that historical analysis, necessarily written with hindsight, often underestimates the uncertainties of the past. The authors call this tendency explanation bias. This bias leads individuals—including professional historians—to imply greater certainty in causal analyses than the evidence justifies. Their analyses will treat what is plausible to be probable. The authors offer a few intuitions about why explanation bias exists, its relation to other well-established psychological biases, what it leads to, and how it might be combatted.

THE NOT-TOO-DISTANT FUTURE—The National Security Council holds an emergency meeting. North Korea has launched a missile, capable of carrying a nuclear warhead within range of U.S. forces in Guam. At this rate, North Korea could land a nuke on the U.S. mainland in less than a year.

Over the past decade, the Arctic has warmed by 0.75°C, far outpacing the global average, while Antarctic temperatures have remained comparatively stable. As Earth approaches 2°C warming, the Arctic and Antarctic may reach 4°C and 2°C mean annual warming, and 7°C and 3°C winter warming, respectively. Expected consequences of increased Arctic warming include ongoing loss of land and sea ice, threats to wildlife and traditional human livelihoods, increased methane emissions, and extreme weather at lower latitudes.

Cyber risk encompasses a broad spectrum of risks to digital systems, such as data breaches or full-fledged cyber attacks on the electric grid. Efforts to systematically advance the science of cyber risk must draw on not only computer science but also fields such as behavioral science, economics, law, management science, and political science.

Repatriating refugees to dangerous countries violates international law and breeds conflict, instability, and future crises. Regional work visas and long-term integration into host countries are more promising solutions.

Over the past quarter century, nearly all major efforts at establishing a durable post–Cold War order on the Eurasian continent have foundered on the shoals of Ukraine. For it is in Ukraine that the disconnect between triumphalist end-of-history delusions and the ongoing realities of great-power competition can be seen in its starkest form.
