Winner of the 2008 Best Book Award, International Security Studies Section of the International Studies Association "David Welch is to be commended for developing an ambitious theory that recognizes that humans, not factors, make decisions, and that they are affected by history and psychology."--Max Paul Friedman, Political Science Quarterly "Welch's theory is original and merits further testing against other cases of foreign policy change. Political scientists and foreign policy practitioners alike would benefit from reading this lucidly written book."--Guy Ziv, International Relations and Political Economy "Well written and accessible to non-specialists... Welch's skillful use of historical materials should please historians in particular... Welch has made a substantial contribution to international relations theory with this book."--Barbara Farnham, International History Review
