Stephen Walt argues for a return to a realism-based U.S. grand strategy.

The small open economies of the Gulf and Southeast Asia are pioneers in the establishment of

Sovereign Wealth Funds (SWFs). The SWFs of countries like Qatar and Singapore are among the

world’s largest in terms of total asset size relative to Gross Domestic Product. This article looks

at the different compulsions behind the setting up of SWFs by small open economies.

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.

States have long worried that their dependence on oil gives producers a means of coercion. The oil market, however, is far larger and more integrated than it used to be. The potential for coercion differs across a series of distinct market segments. In this varied market, the United States remains the dominant force.

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.

By analyzing the institutions that have been created to stimulate energy technology innovation in the United States, the United Kingdom, and China—three countries with very different sizes, political systems and cultures, natural resources, and histories of involvement in the energy sector—this article highlights how variations in national objectives and industrial and political environments have translated into variations in policy.

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR．The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid／small size fossil plants economically．This paper reviews the history and current status of SMR and ASPWR，and also discusses the design concepts, safety features and other advantages thereof.

Africa is yet to adopt full scale technology-led development. Steve Mbogo spoke to the Director of the Belfer Center's Science, Technology, and Globalisation Project and professor at Harvard University Calestous Juma on the opportunities that await the continent as a late comer.

"The challenge is finding an entry point for fostering science, technology and engineering cooperation between China and Africa. An obvious starting point is agriculture. There are two reasons for this suggestion. First, agricultural transformation was one of the first major programs launched by China after the adoption of the 1982 constitution."
