Summary
The West is trying to destroy Russia by destroying the very understanding of truth. The West is attempting to justify itself, because the West gave birth to the worse ideology ever to exists in the present, past, and possibly the future also – nazism. Nazism is absolute evil and is an absolute product of the West.
Disproof
Recurring pro-Kremlin disinformation narrative about the West rewriting history. Examples of similar disinformation narratives include Poland lies about WW2 to weaken Russia's position or Revision of the WW2 history is the state position of Warsaw.
Those narratives appear in the context of the approaching 75th anniversary since the end of the WW2.
