Threats & Vulnerabilities

At the 2014 Hague Nuclear Security Summit, world leaders reaffirmed that it is the fundamental responsibility of states to take “appropriate measures to prevent non-state actors from obtaining [nuclear and other radioactive materials]….which could be used for malicious purposes.” The following reports provide analysis on what threats and vulnerabilities exist today. These documents are drawn from Harvard Kennedy School’s Belfer Center for Science and International Affairs, as well as from other leading scholars and organizations working on issues of nuclear security and nuclear terrorism. 


Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?
March 2016 | Report
By Matthew Bunn, Martin Malin, William Tobey, and Nickolas Roth

This report provides a global assessment of nuclear security. Significant progress has been made securing vulnerable nuclear weapons-usable material—reducing the number of countries with these materials by more than half, securing scores of sites around the world, and much more. But the work is not done. There are new threats, and global attention to nuclear security may be waning. (click here to view)

By Matthew Bunn, Yuri Morozov, Rolf Mowatt-Larssen, Simon Saradzhyan, William H. Tobey, Viktor I. Yesin, Pavel S. Zolotarev

Researchers from the United States and Russia have issued a joint assessment of the global threat of nuclear terrorism, warning of a persistent danger that terrorists could obtain or make a nuclear device and use it with catastrophic consequences. The first joint threat assessment by experts from the world’s two major nuclear powers concludes: “If current approaches toward eliminating the threat are not replaced with a sense of urgency and resolve, the question will become not if but when, and on what scale, the first act of nuclear terrorism occurs.” (click here to view)

Threat Perceptions and Drivers of Change in Nuclear Security Around the World: Results of a Survey
March 2014 | Report
Harvard Kennedy School | Belfer Center for Science and International Affairs
By Matthew Bunn and Eben Harrell 

Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years. This goal implied that many countries would change their nuclear security policies. But the factors that drive changes in nuclear security policies, and that constrain those changes, are not well understood. We conducted a survey of selected nuclear security experts in countries with nuclear weapons, highly enriched uranium (HEU), or separated plutonium, to explore this issue. This paper describes the survey, its results, and implications for next steps to strengthen global nuclear security. (click here to view)

Terrorist Nuclear Weapon Construction: How Difficult?
September 2006 | Journal Article
The ANNALS of the American Academy of Political and Social Science
By Matthew Bunn and Anthony Weir

The likelihood of a nuclear terrorist attack depends in part on the ability of terrorist groups to acquire, construct, and detonate a nuclear device. This article attempts to determine the difficulty of such an endeavor by examining the underlying physical facts about nuclear fission, nuclear materials, and nuclear weapons design. The facts bear out a simple conclusion: while the danger should not be exaggerated, a nuclear terrorist attack is potentially within the capabilities of a well organized and sophisticated terrorist group. A nuclear attack might be one of the most difficult missions a terrorist group could hope to try, but if a highly capable group acquired a stolen nuclear bomb or enough nuclear material to make one, there can be few grounds for confidence that they would be unable to use it.

Living in the Era of Megaterror 
September 2012 | Op-Ed
New York Times | International Herald Tribune
By Graham Allison

"Forty years ago this week at the Munich Olympics of 1972, Palestinian terrorists conducted one of the most dramatic terrorist attacks of the 20th century. The kidnapping and massacre of 11 Israeli athletes attracted days of around-the-clock global news coverage of Black September’s anti-Israel message. Three decades later, on 9/11, Al Qaeda killed nearly 3,000 individuals at the World Trade Center and the Pentagon, announcing a new era of megaterror. In an act that killed more people than Japan’s attack on Pearl Harbor, a band of terrorists headquartered in ungoverned Afghanistan demonstrated that individuals and small groups can kill on a scale previously the exclusive preserve of states."

"Dirty Bombs": Technical Background, Attack Prevention and Response, Issues for Congress
June 2011
Congressional Research Service
By Jonathan Medalia

This report outlines the danger posed by radiological dispersal devices (RDDs), as well as national- and international-level efforts to prevent RDD acquisition by terrorists. The likelihood of an RDD event has decreased due to the work of the NRC, NNSA, and IAEA, and the National Response Framework provides a comprehensive response plan to a domestic RDD incident. CRS also outlines the dilemmas facing congress, such as what weight Congress should give countering RDDs vs other CBRN weapons, if Congress should prioritize securing domestic or international radiological sources, and if cities should establish radiological detection systems.

March 2010 | Book Excerpt
Foreign Policy | Free Press
By David Albright

"The image of Osama bin Laden discussing nuclear weapons around a campfire with two former senior Pakistani nuclear engineers is the stuff of movies. Yet it actually happened in August 2001, when A.Q. Khan's deal with Libya was in full swing....Despite the improvements in intelligence since 2001, terrorist work on nuclear weapons is incredibly difficult to discover…. Stopping terrorists from detonating a nuclear explosive is a crucial challenge. [This account] represents a true nightmare, but should also be an urgent wake-up call.” (click here to view)

Proliferation and Terrorism: Big Hype or Biggest Threat?
March 2010 | Article
Bulletin of the Atomic Scientists
By Rolf Mowatt-Larssen

"On 9/11, Al Qaeda rewrote the terrorist playbook by executing mass casualty attacks against strategic U.S. targets. In essence, these attacks ended one era and ushered in a new one. It is an age in which a few terrorists hold the means to alter the course of history with a single blow. Having set a standard that dares to change the world, it is likely only a matter of time before 9/11 is eclipsed by an even more devastating event. So, why has it not happened yet?"

It first presents a summary of the commercially available radioactive sources, dispersal methods, and exposure pathways that could be deployed in a radiological attack." (click here to view)

The Armageddon Test
August 2009 | Discussion Paper
Harvard Kennedy School | Belfer Center for Science and International Affairs

"Understanding the anatomy of terrorist nuclear intent is essential in order to successfully confront this threat. Two terrorist groups have learned many practical lessons on the difficulties of acquiring a nuclear bomb. The Japanese cult group Aum Shinrikyo and al Qaeda have examined all three pathways to a bomb over years of persistent efforts managed at the top of their respective organizations. Although the terrorist groups worked independently, they shared striking similarities in their thinking and approaches that provide valuable insight into the intrinsic nature of the nuclear terrorism threat."

Deterring State Sponsorship of Nuclear Terrorism
September 2008 | Report
Council on Foreign Relations
By Michael A. Levi

"The basis of nuclear doctrine during the Cold War was deterrence. Nuclear powers were deterred from attacking each other by the fear of retaliation. Today, much of the concern over possible nuclear attack comes in the context of rogue states and terrorism....Michael A. Levi analyzes this aspect of deterrence in the post–Cold War world, as well as what to do if deterrence breaks down....The report also discusses the role of nuclear attribution—the science of identifying the origin of nuclear materials—in deterring transfers, an essential link in assigning responsibility to governments for transfers of nuclear materials."

Nuclear Terrorism: A Disheartening Dissent
June 2006 | Journal Article
By Anna M. Pluta and Peter D. Zimmerman

"A notable recent plea for calm comes from Robin Frost, who, in a December 2005 IISS Adelphi Paper, argues ‘that the risk of nuclear terrorism, especially true nuclear terrorism employing bombs powered by nuclear fission, is overstated, and that popular wisdom on the topic is significantly flawed’. We find this too complacent. The fissile material is available, or could become available, from a Russian nuclear stockpile that remains dangerously insecure. An improvised nuclear device would be difficult, but not too difficult, to build." (click here to view)
