The central belief in case-study approach is that any explanation of foreign policy behaviours through generalisations would cause the loss of unique factors that make up a foreign policy action and creating patterns, models and theories, and trying to fit the foreign policy behaviour of states into these, ignore the essence of foreign policy that is being explained (Tayfur, 1994, 126). According to this approach, each state has different social, historical, cultural backgrounds which consequently differentiate their foreign policies.
