This paper is a background review representing part of the initial phase of the Financing the Urban Transition work program. The review builds on a growing body of research that highlights both the importance of national sustainable infrastructure and the need to develop more effective and efficient financing mechanisms for delivering compact, connected cities that meet the UN’s Sustainable Development Goals. While progress has been made in both these areas over the last five years, there remains a policy gap between the international/national level and the municipal level.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

The last seven decades without war among the great powers – what historians describe as “the long peace” – is a remarkable achievement. “This is a rare and unusual fact if you look at the last few thousand years of history,” said Graham Allison, director of the Belfer Center and moderator of the IDEASpHERE panel “Winning the Peace.” “Furthermore, it is no accident. Wise choices by statesmen have contributed to ‘the long peace,’ which has allowed many generations to live their lives.”

The United States and India have a strong and shared interest in preventing extremist groups from using Afghanistan as a base from which to launch terror attacks. If our two countries work together to foster stability in Afghanistan without provoking a counterproductive Pakistani response, we can further our Strategic Partnership and advance peace and security in South Asia.

Given the seriousness of the ongoing standoff on the Korean peninsula, South Korea's emergence as an active contributor to international security addressing challenges far from the Korean peninsula is a striking new development, marking South Korea's emergence as a producer rather than a consumer of global security resources. This volume outlines South Korea's progress and accomplishments toward enhancing its role and reputation as a contributor to international security.

Nearly all of the 190 signatories to the Nuclear Non-Proliferation Treaty (NPT) agree that the forty-two-year-old treaty is fragile and in need of fundamental reform. But gaining consensus on how to fix the NPT will require reconciling the sharply differing views of nuclear weapon states and non-nuclear weapon states. Strengthening the international rules is increasingly important as dozens of countries, including some with unstable political environments, explore nuclear energy. The result is an ever-increasing distribution of this technology. In this paper, Steven E. Miller outlines the main points of contention within the NPT regime and identifies the issues that have made reform so difficult.

In the Foreword to this paper by Andrei Kokoshin, Belfer Center Director Graham Allison writes: "The global nuclear order is reaching a tipping point. Several trends are advancing along crooked paths, each undermining this order. These trends include North Korea’s expanding nuclear weapons program, Iran’s continuing nuclear ambitions, Pakistan’s increasing instability, growing doubts about the sustainability of the nonproliferation regime in general, and terrorist groups’ enduring aspirations to acquire nuclear weapons. Andrei Kokoshin, deputy of the State Duma and former secretary of Russia’s Security Council, analyzes these challenges that threaten to cause the nuclear order to collapse in the following paper."

The following study focuses on the threat of nuclear terrorism facing Israel. It begins with an overview of the nature of the threat, before turning to the potential perpetrators of nuclear terrorism against Israel, possible delivery mechanisms and targets, and the specific scenarios under which the threat to Israel might materialize. The study then presents possible policy options for Israel to deal with the threat, both unilaterally and in conjunction with the United States.

Matthew Kroenig examines the effect of the spread of nuclear weapons on international politics in a Managing the Atom Working Paper.  He observes that the spread of nuclear weapons threatens some states more than others, and proposes a theory of nuclear proliferation that examines the differential effects of proliferation.  He argues that the threat nuclear proliferation poses to a particular state depends on that state’s ability to project military power.  The spread of nuclear weapons is worse for states that have the ability to project conventional military power over a potential nuclear weapon state because nuclear proliferation constrains their conventional military freedom of action.
