Comparative foreign policy (CFP) emerged as a distinct research program in foreign policy analysis (FPA) during the period of the behavioural revolution in the United States in the 1960s and the 1970s. It gradually faded away in the field because it failed to develop generalizable, grand foreign policy theories as originally intended. Through examining three CFP-related approaches, the area-studies school, the middle-range theory, and the specific-actor approach, this chapter suggests that we should bring CFP back to FPA as a distinct analytical approach instead of a research program with concrete research agendas. The three “comparative” methods of the CFP approach to FPA, comparative case, comparative theory, and comparative method are illustrated and evaluated with empirical research.
