The flaws in your argument as I see it.
1. "various individuals to have an exaggerated sense of their impact": The Impact of Russia on the 2016 election was not well understood, and not made public until after Trump was elected. "Sense of impact" implies a non-factual view of the events of what happened in 2016. Problem with that assumption is that we have had The Mueller Investigation and subsequent Report that spells out exactly what happened, factually. Which may soon become available unredacted.
2. Various members of the US Intelligence Community, Including the FBI Director, and DNI Coates, have testified under oath to Congress that Russia is now and will continue to intervene in the upcoming election.
