This essay examines Russia’s growing role in Asia’s energy markets, assesses the implications for the U.S., and examines the claim that closer Sino-Russian energy ties are adding new incentives for a broader strategic alignment.

Since the Paris Agreement's adoption in 2015, a majority of the world's largest investors have begun to take action on climate change. According to a new report, the 2016–2017 year showed an average improvement in decarbonization within all major investor categories except pension funds.

In trying to prevent adversaries from acquiring new military capabilities, countries often employ strategies of arms denial; e.g., “unilateral diplomacy,” supply chain interdiction, covert sabotage, and targeted military strikes. Using a game-theoretical model of weapons acquisition and denial, the authors posit that the prevalence of this approach gives rise to strategic effects that affect all players’ behavior.

A central debate in the study of energy geopolitics concerns the relative importance of the Sino-Russian energy alliance and the lack of the long awaited deal in natural gas. The deadlock in natural gas is all the more puzzling when contrasted to the two countries’ flourishing ties in oil. In this paper, Morena Skalamera explores these developments by comparing the outcomes of the two deals and highlighting the distinctiveness of oil trade vis-à-vis gas trade.

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.”

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.

There has been much speculation as to what might replace the Nuclear Security Summits after 2016. One candidate touted as a suitable inheritor of the summits’ mantle is the International Atomic Energy Agency. In this discussion paper, Trevor Findlay examines whether and to what extent the IAEA could and should do so, what form its role might take, and how the Agency and summiteers might prepare for such an eventuality.

The Belfer Center’s Eben Harrell and Pulitzer Prize-winning author David E. Hoffman for the first time report the details of one of the largest nuclear security operations of the post-Cold War years — a  secret 17-year, $150 million operation to secure plutonium in the tunnels of Degelen Mountain.
