The phrase “post-Soviet space” is often used to denote a specific geographical area-countries and territories that were part of the former Soviet Union. In this chapter, however, I offer a slightly different reading of the term “post-Soviet space.” Rather than focusing on ethnic, cultural, and national borders that differentiate Russia from what used to be the Soviet Union, the political aspect is sought in what is actually the functional component of the Russian/Soviet territory: the infrastructure network.
