This is the third installment in a series of JSPPS discussions on the conceptualization of the ideology of the Organization of Ukrainian Nationalists during World War II. The sections in this series are not classical assemblies of peer-reviewed research papers on a particular theme, but constitute a round-table-like debate consisting of interactive interventions by senior and junior scholars from the disciplines of comparative fascism and Ukrainian nationalism. The discussion originated from two intriguing conceptual articles on interpretative and classificatory issues in the comparative study of European and, in particular, East European permutations of interwar and wartime right-wing radicalism, as well as on the utility of an application of new overarching taxa to them.
