Aleksandr Dugin Aleksandr Gelyevich Dugin (Russian: Алекса́ндр Ге́льевич Ду́гин ; born 7 January 1962) is a Russian political analyst, known for his fascist views, who calls to hasten the "end of times" with all-out war. He has close ties with the Kremlin and the Russian military, having "served as an advisor to State Duma speaker Gennadiy Seleznyov and key member of the ruling United Russia party Sergei Naryshkin. However, commentators dispute his influence: in the words of journalist Alexander Nevzorov, "if we had had Sergey Kurginyan and Dugin instead of Putin, there would have been hell for all of us to pay, they would have unleashed a European and World War without a shadow of a doubt, without considering consequences at all." But "Dugin and Kurginyan do not have the slightest impact on what is going on in the Kremlin and do not even get coaching there". Dugin was the leading organizer of the National Bolshevik Party, National Bolshevik Front, and Eurasia Party. He is the author of more than 30 books, among them "Foundations of Geopolitics" (1997) and "The Fourth Political Theory" (2009).
