Recently the concept of “diaspora” has become a popular subject and two polarized views dominate the study on diaspora behavior: the categorization of the diaspora as good or bad, conflict or peace promoter, spoiler or peace-maker. The majority of the research on diaspora politics places emphasis on its conflict-promoting character. Researchers argue that a diaspora may even act against its homeland’s interests. This paper aims to further explore this behavior of diaspora groups and try to locate the reasons behind this phenomenon. The focus is the Armenian diaspora and its policies, particularly targeting the foreign policy of the host country. Some of the critical issues are the conflict in Nagorno Karabakh and Turkey-Armenia relations, which includes the issues of “genocide” recognition, normalization of diplomatic relations and opening of the borders. With the help of theoretical frameworks, the Armenian diaspora’s positions will be analyzed in this paper.
