Acknowledgments

The authors would like to thank all of the participants in the December 2011 American Academy of Arts and Sciences workshop on Insider Threats held at the Center for International Security and Cooperation (CISAC) at Stanford University. In addition, we thank Roger Howsley, Executive Director of the World Institute of Nuclear Security (WINS), for inviting us to present some of our preliminary findings on this subject at WINS workshops in Vienna, Austria, and in Johannesburg, South Africa. We also express our gratitude to the participants in the CISAC Nuclear Studies Reading Group, sponsored by the John D. and Catherine T. MacArthur Foundation, at which a first draft of this paper was presented, and to the International Atomic Energy Agency for hosting the conference on International Nuclear Security in July 2013, where some of these ideas were also presented.

Matthew Bunn thanks Nickolas Roth and Laura Dismore and Scott Sagan thanks Anna Coll and Reid Pauly for their research assistance related to this paper. Both of us also thank Francesca Giovannini for her superb work as the program officer for the Global Nuclear Future Initiative at the American Academy. Our collaborative work has been made immeasurably better by the dedicated support from and careful research conducted by these talented members of the next generation of international security specialists.

Finally, on behalf of the American Academy of Arts and Sciences, we would like to thank the foundations that have allowed us to work on Insider Threats and on other nuclear related issues throughout the course of the Academy’s Global Nuclear Future Initiative. We are deeply grateful to Carnegie Corporation of New York, The William and Flora Hewlett Foundation, The John D. and Catherine T. MacArthur Foundation, The Alfred P. Sloan Foundation, the Flora Family Foundation, and the Kavli Foundation for their support.
