The Low-Yield Nuclear Warhead: A Dangerous Weapon Based on Bad Strategic Thinking

In the unintuitive world of nuclear weapons strategy, it’s often difficult to identify which decisions can serve to decrease the risk of a devastating nuclear conflict and which might instead increase it. Such complexity stems from the very foundation of the field: Nuclear weapons are widely seen as bombs built never to be used. Historically, granular—even seemingly mundane—decisions about force structure, research efforts, or communicated strategy have confounded planners, sometimes causing the opposite of the intended effect.

Public Testimony on Trump Administration Funding for Nuclear Theft Preventing Programs

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

Why Matter Matters: How Technology Characteristics Shape the Strategic Framing of Technologies

The authors investigate how the executives of the two largest research institutes for photovoltaic technologies — the National Renewable Energy Laboratory (NREL) in Golden, USA and the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Freiburg, Germany — have made use of public framing to secure funding and shape the technological development of solar photovoltaic (PV) technologies. The article shows that the executives used four framing dimensions (potential, prospect, performance, and progress) and three framing tactics (conclusion, conditioning, and concession), and that the choice of dimensions and tactics is tightly coupled to the characteristics of the specific technologies pursued by the research institutes.

Green Ambitions, Brown Realities: Making Sense of Renewable Investment Strategies in the Gulf

Gulf countries have hailed their investments in renewable energy, but some basic questions remain about the extent to which it makes sense for GCC states to invest aggressively in renewables. The sheer magnitude of such investments will require these countries to mobilize significant public resources.  Therefore, such an assessment requires these countries to focus on national interests, not just a desire to be perceived as constructive participants in the global transition away from carbon energy. 

This report starts by identifying four common strategic justifications for investing in renewable energy in GCC countries. Each of these rationales highlights a different aspect of renewable energy investments. In addition, each rationale is based on different assumptions about the underlying drivers of such investments, and each rationale is based on different assumptions about the future of energy.

Hong Kong, a Democratic Voice in China

Hong Kong is unique. While the writer Han Suyin’s description—“a borrowed place, on borrowed time” —seemed redundant upon the return of the territory to China on July 1, 1997, the former British colony appears to be perpetually exposed to uncertainty over its future. Despite long months of sociopolitical crisis and violence, Hong Kong has once again shown that it has lost none of its personality. Amidst the climate of upheaval and faced with a Chinese regime determined to obstruct any hopes of democracy, the people of Hong Kong have managed to attract international and media attention, marking them out from any other Chinese territory—including those that enjoy special status: Tibet, Inner Mongolia, Macao, and even Xinjiang, where nearly a million people from the minority Uyghur ethnic group are confined to “re-education” camps. No other Chinese region has been able to attract such attention.

The Case for Transatlantic Cooperation in the Indo-Pacific

The evolving strategic dynamics in the Indo-Pacific are of paramount importance for the future of the rules-based international order. While the United States is redirecting strategic focus to the region as part of its Free and Open Indo-Pacific strategy, Europe is also stepping up its role—leveraging a strong economic profile, long-standing bilateral ties, and active engagement in various regional multilateral forums. The European Union (EU) and its member states can make distinct contributions to an open, transparent, inclusive, and rules-based regional order, though not necessarily always in lockstep with Washington.

The Strategic Postures of China and India: A Visual Guide

Fueled by aggressive rhetoric from both capitals, Indian and Chinese ground forces engaged in a standoff between June and August 2017. The Doklam crisis, as it became known, stimulated introspection among officials and experts in both states about the future of their relationship. Politically, both strategic communities largely concluded that the peaceful resolution of border disputes is now less likely, forecasting more rivalry than cooperation. Militarily, Indian discussions on the strength of its military position against China in their disputed ground frontier areas have converged on the view that China holds the conventional and nuclear edge over India in this domain.

Based on our analysis of data on the location and capabilities of Indian and Chinese strategic forces and related military units, we conclude that this assessment of the balance of forces may be mistaken and a poor guide for Indian security and procurement policies. We recommend that instead of investing in new nuclear weapons platforms that our analysis suggests are not likely to be required to deter China, New Delhi should improve the survivability of its existing forces and fill the gap in global arms control leadership with an initiative on restraint and transparency.
