Aleksandr Dyukov graduated from the Russian State University for the Humanities in 2004. The topic of his dissertation was the Soviet partisan movement in 1941–1943. From 2004 to 2007, Dyukov worked for the ARMS-TASS Agency of Military and Technical Information. He contributed as issuing editor of the weekly Military and Technical Cooperation, later promoted to its editor-in-chief. He has published numerous articles in the newspapers Izvestia, Komsomolskaya Pravda, REGNUM News Agency and elsewhere focusing on Soviet history in the 20th century. After publishing two of Dyukov's books, REGNUM has since ceased cooperation with him following a conflict over Dyukov's statements in the Russian and Estonian media that his Historical Memory Foundation was primarily responsible for these publications.
Dyukov has been featured as an expert historical commentator on Novosti's Russia Today cable channel and on their web site. Dyukov is a member of the working group set up by the Russian State Duma preparing a draft for a law on combating the rehabilitation of Nazism.
One of Dyukov's spheres of interest is the history of Soviet repression, mostly in the Baltic states and Ukraine. While Dyukov employs open archives such as from the State Archive of the Russian Federation (GARF) and the Russian State Archive of Contemporary History (RGANI), he also cites the archives of the FSB, to which access by researchers is limited. It is these FSB archives which Dyukov uses, for example, to claim in his recent book, The Genocide Myth, that Estonia's recollection of Soviet repressions including deportations is exaggerated. In regard to the June 1941 deportations, that took place before German invasion of June 22, 1941, Dyukov contends that deported Estonians were mostly German collaborators or were linked to them.
In a 2007 interview with Russia's REGNUM News Agency Dyukov claimed that some Estonian historians were repeating false claims by the Nazi propaganda and said: Another example of unfair approach Estonian official historians is that in describing the deportation of 14 June 1941, they always mention that the deportees were transported in stock cars, with each car stuffed to 40-50 people, including women, children and the elderly. Therefore, they say, this deportation caused massive mortality. However, if we turn to the NKVD documents, a fair amount of which has already been published, one finds that, firstly, the transportation of deportees was carried out in passenger cars "equipped for summer human traffic." Secondly, each railroad car carried not 40-50, but about 30 deportees. Third, according to railroad documents, mass death was impossible. It can't be ruled out that during this deportation, not a single person died. Estonian historians, by the way, somehow forget that in every echelon of deportees there was an ambulance railroad car, which was accompanied by a doctor, paramedic and two nurses. In reaction to Dyukov's book, the newspaper Eesti Ekspress in Estonia denounced him as a revisionist historian who paints a picture of Soviet political repressions as "little worse than a family picnic".
