“…The ES's interpretative strengths, correspondingly, lie in its awareness of history (Linklater & Suganami, 2006, 84-97); its elaboration of a three-stranded dynamic as a framework of thought for interstate politics (Bellamy, 2005a, 294;Suganami, 2005, 41-2); its focus on agency (Dunne, 1998, 120;Keens-Soper, 1978, 40;Suganami, 2005, 33) and social practice (Navari, 2010); and its modest pointer to the possibility of building 'a "theory" -in the sense of an "interpretation" -of world history which embodies a cautious and mild form of progressivism' (Suganami, 2005, 42). These are the theoretical strengths that this book will seek to harness.…”
