All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

The fourth and final Nuclear Security Summit took place in Washington DC from March 31-April 01, 2016.  Despite the initial apprehension about the summits in certain parts of the world, it has been a useful process.  With more than 50 countries represented from across the world, the summits elevated the level of awareness of nuclear security. Leaders of established nuclear states began to think about nuclear security in a new way, reducing complacency about the risks of terrorism and sabotage.  This thinking took shape in national and multilateral commitments in areas including nuclear security regulation, physical protection of nuclear materials, nuclear forensics, protection against nuclear smuggling, and insider threats and nuclear terrorism.

When do states acquire nuclear weapons? History shows that only two types of states decide that the bomb is essential to their security: 1) very powerful states; and 2) weak states that lack ironclad security guarantees.

Policymakers have long focused on preventing nuclear weapons proliferation by controlling technology. Even developing countries, however, may now possess the technical ability to create nuclear weapons. The history of gas centrifuge development in twenty countries supports this perspective. To reduce the demand for nuclear weapons, policymakers will have look toward the cultural, normative, and political organization of the world.

"In our view, the field has moved away from a careful reliance on theory, and is just mindlessly going out and testing hypotheses without thinking very hard about what's really causing what."

This article finds that there were severe shortcomings in the acquisition and processing of information and a lack of institutional self-evaluation; civilian and military leaders made major strategic misjudgements in mistaking the strategy for the goal, overestimating the efficacy of military force or resources, and drawing false lessons from history or analogous cases such as Iraq; leaders were predisposed to overconfidence and oversimplification; and, at the highest level, policies were distorted by domestic politics. The article contends that the cumulative impact of these shortcomings was sufficient to seriously disrupt the functioning of the foreign policy-making system.

"While journalists have provided a number of histories of the events that led to bin Laden's death, the purpose of this analysis is to examine White House decisionmaking for lessons that can be applied to future foreign policy challenges."

In a TIME magazine cover story, Belfer Center Director Graham Allison writes about decisions behind the raid that led to the death of Osama bin Laden. Allison, whose analysis is the result of more than 100 hours of interviews, is author of the prize-winning analysis of the 1971 Cuban Missile Crisis, Essence of Decision.

The Kyoto Protocol establishes a very complex and ambitious regime, in architecture if not stringency. The problem is that relatively few states, representing only about a quarter of the world's emissions, have been willing to assume emission targets under Kyoto....The future of the Protocol thus seems doubtful at best. Even in the most optimistic scenario, a new round of emissions targets couldn't be agreed in time to prevent a legal gap between the first and second commitment periods. A possible middle ground would be to establish a transitional regime that would be political in nature, but that could evolve over time into a legally-binding regime.
