Controlled warfare: how directed-energy weapons will enable the US Military to fight effectively in an urban environment while minimizing collateral damage

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military.     

Keeping Nothing Secret: United Kingdom Chemical Warfare Policy in the 1960s

After renouncing an offensive chemical warfare programme in 1956, the UK Cabinet Defence Committee decided in 1963 to re-acquire a chemical warfare retaliatory capability. This article describes how the re-acquisition decision was engendered by a combination of novel research findings, changes in strategic thinking, new intelligence and pressures from NATO. Despite the 1963 decision, no new chemical weapons capability was acquired by the UK and information that Britain lacked a stockpile of chemical weapons was eventually leaked to the public, initiating a fierce debate between ministries over the significance of this leak. This paper argues that non-existent technology is equally problematic for government secrecy, and equally consequential for government action, as what exists. Furthermore, actors' different interpretations of what constituted a secret, point towards a more subtle understanding of secrecy than simply construing it as the hiding or uncovering of items of information.     

Russia and Strategic Conventional Weapons:

ABSTRACT

Russian political leaders and military strategists are growing increasingly concerned about “strategic conventional weapons”—a broad category that appears to include all non-nuclear, high-precision, standoff weapons—and about long-range, hypersonic weapons, in particular. These concerns are complex and multifaceted (and, in some cases, contradictory), but chief among them are the beliefs that strategic conventional weapons could prove decisive in a major conflict and that Russia is lagging behind in their development. US programs to develop and acquire such weapons—namely, the Conventional Prompt Global Strike program—are of great concern to Russian strategists, who argue both that the United States seeks such weapons for potential use against Russia—its nuclear forces, in particular—and because strategic conventional weapons are more “usable” than nuclear weapons. Asymmetric responses by Russia include increased reliance on tactical nuclear weapons, efforts to enhance the survivability of its nuclear forces, and investments in air and missile defenses. There is also strong—but not completely conclusive evidence—that Russia is responding symmetrically by attempting to develop a long-range, conventionally armed boost-glide weapon.     

Boost-glide Weapons and US-China Strategic Stability

ABSTRACT

The United States and China are testing boost-glide weapons, long-range strike systems capable of flying at Mach 5 or faster through the upper atmosphere. For the United States, these systems would provide a conventional prompt global strike capability, which, together with US ballistic missile defense programs, Chinese experts regard as a threat to China's ability to conduct nuclear retaliation. This perception is encouraging the Chinese military to modify its nuclear posture in ways that tend to create greater risks for both sides. If China's own boost-glide systems are meant to carry nuclear payloads only, their deployment would not fundamentally alter the current situation between the two states. However, if they were conventionally armed or dual-purpose, or if the United States could not determine the payloads they carried, the deployment of Chinese boost-glide systems could compound problems of strategic stability created by the introduction of ballistic missile defense, antisatellite, and antiship ballistic missile capabilities. If the technical hurdles can be overcome, it may be difficult for the two sides to refrain from these deployments in the absence of strong mutual trust or an established arms-control relationship. New confidence-building measures and expanded mutual transparency are warranted to avoid creating new dangers.     

FACILITATING NUCLEAR DISARMAMENT: Verified Declarations of Fissile Material Stocks and Production

Unprecedented interest in seeking progress toward nuclear disarmament exists today; even some nuclear weapon states are looking for new ways to strengthen this process. National declarations of fissile material holdings—highly enriched uranium and plutonium—could play an important role in supporting this effort, facilitating not only transparency but also the irreversibility of the process. This article discusses what kind of content such declarations could have in order to be meaningful and effective, the sequence of data on fissile material holdings that states might release, and some of the challenges to be expected in reconstructing historic fissile material production; it also summarizes current attitudes of weapon states toward making such declarations. Initial declarations can be valuable as confidence-building measures, but better and more background data are necessary if declarations are to serve as the groundwork for deeper cuts in the nuclear arsenals. A robust verification approach would ultimately require inspectors to have access to fissile material production and storage sites. The methods and tools of nuclear forensic analysis—in this context also dubbed nuclear archaeology—would be a key element of this process. This article discusses the capabilities and limitations of potential approaches to verifying declarations of historic production of plutonium and highly enriched uranium; it also identifies and discusses opportunities for further research and development.

Comprehensive Prohibition of Nuclear Weapons: An Emerging International Norm?

ABSTRACT

There have been calls for the abolition of nuclear weapons from the day they were invented. Over the last fifteen years, some indications can be found that such calls have been getting louder, among them Barack Obama's famous 2009 speech in Prague. In this article, we investigate if support for a comprehensive norm that would prohibit development, possession, and use of nuclear weapons is really growing. To assess the current status of that norm, we use the model of a “norm life cycle,” developed by Martha Finnemore and Kathryn Sikkink. We then analyze 6,545 diplomatic statements from the review process of the Treaty on the Non-Proliferation of Nuclear Weapons as well as from the UN General Assembly First Committee on Disarmament and International Security, covering the years 2000 to 2013. The evidence shows that a comprehensive prohibition can be considered an emerging international norm that finds growing support among states without nuclear weapons and nuclear weapon states alike. Only a core group of states invoke the norm consistently, however. This leads us to conclude that the “tipping point” of the life cycle, at which adherence to a new norm starts to spread rapidly, has yet to be reached.     

BIOLOGICAL AND CHEMICAL WEAPONS ARMS CONTROL IN THE MIDDLE EAST

Nonproliferation policies to prevent biological and chemical weapons use are important, but insufficient, particularly in view of the rise of global terrorism. Given the history of developing and using these weapons, it is crucial that governments properly prepare for biological and chemical threats, whether naturally occurring or man-made, such as by developing and managing effective healthcare infrastructure to mitigate widespread illness and injuries resulting from pandemics or terrorist attacks. Although the Middle East is one of the most sensitive and complex areas in the world—especially regarding regional arms control efforts and prevention—coordinating preparedness strategies among states in the region may be possible. Cooperatively addressing biological and chemical threats could lead to constructive progress towards the otherwise elusive goal of establishing a weapons of mass destruction-free zone in the Middle East.
