In completing this book, I am particularly happy to have an opportunity to express my thanks to those who have so generously helped me in my work on it. I owe an enormous debt of gratitude to Byron Shafer, whose excellence as an adviser and mentor I cannot overstate. Tony Badger, Nigel Bowles, Gareth Davies, Nelson Polsby, Sukhdev Sandhu, and Marc Stears all read the entire manuscript, and their comments were immensely beneficial, as were those of the anonymous reviewers. I have also been very lucky to receive advice, assis- tance, and encouragement from many others, including Sybill Bidwell, Richard Fenno, Anupam Gupta, Paul Martin, John Mason, Sarah Mason, David May- hew, Bent Nielsen, Richard O'Leary, Jacqui Pearse, Tom Perrett, Allen Pitt, John Rowett, Petra Schleiter, Rebecca Short, and Robert Singh. Of great benefit to my research was the guidance of librarians and archivists at Rhodes House Library in Oxford, the Nixon Presidential Materials Project at the National Archives, the Gerald R. Ford Library, and the Manuscripts Division at the Library of Congress. I am most fortunate to work among a supportive and generous group of historians at Edinburgh, and my fellow Americanists— Frank Cogliano, Alan Day, Owen Dudley Edwards, and Rhodri Jeffreys- Jones—have been especially dependable and valuable sources of advice and help. At Edinburgh I have learned much, too, about this topic from my students. For their financial support, I am grateful to the British Academy; Nuffield College, Oxford; the University of Edinburgh; the Gerald R. Ford Foundation; and the Eisenhower World Affairs Institute. The staff at the Uni- versity of North Carolina Press, notably Charles Grench, Amanda McMillan, Paula Wald, and, until his departure, Lewis Bateman, have guided this book toward publication in an encouraging as well as expert way, and the contribu- tion of copyeditor Ellen Goldlust-Gingrich was valuable. To all those who have provided in countless ways help and support—absolutely essential during this project—I am deeply grateful.
