In this chapter, the author argues that "territorial nationalism" has not disappeared, but has adapted. The territorial aspect of nationalism have been discredited and rendered illegitimate by both international law and practical norms, but nationalist entrepreneurs have imagined new forms of political identification and mobilization with new modalities of legitimation, and the discourse of "diaspora" has gained a central position in these enterprises. The chapter precisely documents how nationalist discourses and practices evolve from a territorial expression to a transnational, diasporic expression, through a study of the practices of the nationalist Croatian party Hrvatska Demokratska Zajednica (HDZ) in Bosnia and Herzegovina. It analyzes the HDZ and its pursuit of a double strategy of official recognition and covert undermining of BiH integrity, motivated by the vision of a "Greater Croatia". The chapter shows how the failure of the territorial annexation is circumvented by using "diaspora politics" to pursue the same objective.
