Geostrategic position is more important than size. Education and communication are more important then space. The huge size of the territory covered by the former Soviet Union, the largest country on earth, contributed to its collapse rather than guaranteeing its survival. The small territory a Refugee Republic would need could be leased by the UN from larger countries or those which have no other way to profit from their lands. Government Refugees should have their own administration and representation.
Refugees lack self-representation.
Democracy, so far, seems to defy implementation on this level. That should be changed. Once an international refugee network has been established, a yet to be defined democratic modality could be developed. The Refugee Republic's sphere of influence is defined by migration routes and communication structures. It is a function of the transparency of national limits.
