Abstract: The purpose of the article is political and philosophical insight into the problem of global disintegration - the main characteristic of the modern stage of international relations, which the author of the work suggests naming a “post-globalization”. The author substantiates the hypothesis about the completion of globalization and the beginning of a post-global period in international relations. The article also reveals the thesis about archaization of politics in modern Russia as a reaction to the beginning of post-globalization. The work contains a methodology paragraph which enunciates the concept of two typical forms of reaction to postglobal changes in international relations. This theory serves as a methodological basis for the applied analysis and the conclusion that archaization of politics has converted Russia from a global power to a regional country. In a wide historical sense, archaization of Russia’s politics proves that the post-Soviet period has been completed in post-Soviet states. Globalization, which is understood as a global integration process, has been completed. In global politics and economics, a centrifugal ideology of disintegration and separation, manifested in a dramatic self-isolation of countries and the beginning of a new “enclosure” of national socio-economic systems, has replaced the strategies of unification. Russia has responded to the current international situation with archaization of both external and internal policies. This path is strategically wrong, and speaks for a degradation of the country’s politics. Improper political reaction to post-globalization has already driven Russia out from the top-list of the countries of influence to the regionally significant countries whose influence is more prominent within their region. The research subjects the author takes as a basis - post-globalization and archaization of Russia’s politics - haven’t been studied sufficiently enough in Russian world literature. At the same time, these problems seem to be urgent, since the author comes to the conclusion that Russia is not ready for the post-global epoch.
