She was among France’s most prominent scholars, ana- lysts, and officials dealing with security issues, especially nuclear weapons. In that conversation, she told me that she had long admired the work on deterrence that was done in the 1950s and 1960s, much of it at RAND in Santa Monica. She lamented the fact that she had not encountered the same level of reflection on today’s deterrence challenges. Of course, those challenges are different, she noted, than those of the time of the U.S.-Soviet nuclear standoff, but that does not necessarily mean that the think- ing from that time is irrelevant. Thus, we hatched the plan for this book. Thérèse was willing to take time from her career in France to come to Santa Monica for weeks at a time to go through RAND’s deterrence literature—a trove of studies that continues to grow today—and to begin to write. She started in Santa Monica, a city she enjoyed, in August 2009. Sadly, she fell ill in the middle of the project. In the early days of her battle with the illness that she never specified, she told me that she was determined to finish the project, working at home in Paris and, if possible, returning to Santa Monica. She did both and she submitted the book for review at RAND in late 2010. She hoped to return in 2011 for the final rewrite, but she was unable to. She finished the rewrite at home a few months before her death. I am both sad and proud that RAND is able to publish what may be her last book. The world has lost a great talent much too young; she had so much more to do. The book is a triumph. Thérèse • spells out the need for revitalization of thinking about nuclear weapons, a chal- lenge that RAND takes seriously • reviews the key concepts of past deterrence thinking and their development up to now • reviews today’s key security challenges and their relation to nuclear weapons • demonstrates that some of the concepts of the past remain relevant today vii viii Nuclear Deterrence in the 21st Century • urges the new generation of defense and security analysts to turn their attention to nuclear deterrence, much as she did 30 years ago. Not everyone will agree with Thérèse’s analysis of today’s security challenges. But this is no surprise: There are significant differences of opinion in the West regarding what to do about the Iranian and North Korean nuclear programs, and the challenges and opportunities posed by the rise of China continue to be debated. But all will learn from this interesting and challenging book. I certainly did. James A.
