The article reveals the methodological potential of the cosmopolitan approach to the study of collective memory as one of the main prerequisites for the formation of group identity and identification of the foundations for the formation of global memory. For this purpose, the civilizational approach of S. Huntington, the paradigmatic approach of J. Heidt and the methodological apparatus of memory studies with its inherent intention to the problem of forming a group identity are used. These methodological tools helped to explain the whole spectrum of modern civilizational transformations and provided an impartial view of the sources of aggressive policy of russia towards Ukraine’s European choice and entire Western civilization. In view of this, the results of the study can be useful for developing a humanitarian policy appropriate to Ukraine’s European choice, in particular, for elaboration of a strategy for the development of Ukrainian memory policy. It must be developed taking into account the ultimate importance of global (universal) memory for overcoming international conflicts for the sake of peace and prosperity of all mankind and understanding the problematic nature of its emergence in the near future due to civilizational differences and economic inequality. Given this, it is important to the modern world to form supranational communities, whose members being aware of the decentralized nature of global processes and the risks involved will focus on creating a system of interstate mechanisms to overcome turbulence to preserve peace and increase human well-being. Despite the noble intentions of the supporters of the cosmopolitan world based on the principles of liberal democracy, their ideas and programs are discern with great caution, and sometimes even with open hostility in cultural environments and communities with different from European collective experience and historical memory. This, in turn, puts on the list of items the need to unite the entire Western world and construct a supranational pan-European identity as a prerequisite for the internal consolidation of European society around core values defined by shared historical memories that underpins European international policy.
