This quote comes from a hard-liner Sergei Naryshkin, head of Russian Foreign Intelligence Service, who is promoting changes to Russian Constitution by covering it up with concerns about history rather than admitting the changes are initiated by Putin’s desire to stay in power.
The timing is also barely accidental, since the comment comes after a recent Putin’s article in National Interest.
Russian establishment is not only actively involved in rewriting history, they are also propagating the idea of a mysterious “Western enemies”, who are allegedly doing the very things that Kremlin is actually doing in real life.
Current regime is trying to monopolize the victory in WW2 to sanctify itself, because if Russia would have a status of an “ultimate savior of the world from Nazism”, Putin can further excuse military invasions, human rights violations and any other atrocities.
