DEFENSE SCIENCE BOARD | DEPARTMENT OF DEFENSE<br />
Executive Summary<br />
The Defense Science Board Task Force on Assessment of Nuclear Treaty Monitoring and<br />
Verification Technologies was established to examine a broad range of questions concerning<br />
the capability of the Department of Defense (DoD), the Department of Energy (DOE) and the<br />
Intelligence Community (IC) to support future <strong>monitoring</strong> and verification of nuclear<br />
nonproliferation and arms control treaties. The Terms of Reference (TOR) for the study, found<br />
in Appendix B, state the tasking. Given the breadth of the topics of interest to our sponsoring<br />
leadership and the time and resources available, the Task Force determined to focus on those<br />
aspects of the TOR that address what it views as the priority issue––namely, <strong>monitoring</strong> for<br />
proliferation. Assessments of strategies for <strong>monitoring</strong> nuclear activities in both permissive and<br />
non‐permissive environments, and of our current technical capabilities and future<br />
requirements for successfully implementing those strategies, were made.<br />
A Nuclear Future Unlike the Past and the Need for a Monitoring Paradigm Shift<br />
Too many factors have changed, and are changing from our historic basis and experience<br />
developed throughout the Cold War. The list of factors that should give national leadership<br />
pause for concern is extensive, and includes the following:<br />
• The actual or threatened acquisition of nuclear weapons by more actors––with a range<br />
of motivations, capabilities, and approaches––is emerging in numbers not seen since<br />
the early days of the Cold War. Many of these actors are hostile to the U.S. and its<br />
allies, and of greater worry, they do not appear to be bound by established norms nor<br />
are they deterred by traditional means;<br />
• In some cases, nuclear forces are seen as the most affordable and effective alternative<br />
to deter superior conventional forces; i.e., nuclear weapons are viewed as a legitimate<br />
warfighting capability, especially if vital domestic or regional security interests are<br />
threatened;<br />
• Fundamental nuclear knowledge is widespread and know‐how increasingly accessible.<br />
o At the same time, ubiquitous information access and widespread observational<br />
tools are increasing inherent transparency;<br />
o However, recognition of such increased transparency by potential or actual<br />
proliferants incentivizes the employment of more sophisticated methods of<br />
denial and deception;<br />
• The pathways to proliferation are expanding to include networks of cooperation among<br />
nations and actors who would otherwise have little reason to do so;<br />
• The growth in nuclear power worldwide offers more opportunity for “leakage” and/or<br />
hiding small programs.<br />
