All Putin has to do is sprinkle a little distrust, and watch us destroy ourselves. He doesn't actually *have* to collude or do much more than green-light the well-documented factories churning out increasingly-sophisticated and targeted Internet disinformation.
Reminds me of this Twilight Zone episode:
https://en.wikipedia.org/wiki/The_Mo...n_Maple_Street
Which, oddly, was written about a similar thing...
The closing narration is both timely for the era the episode released in, and still applies today:
"The tools of conquest do not necessarily come with bombs and explosions and fallout. There are weapons that are simply thoughts, attitudes, prejudices...to be found only in the minds of men. For the record, prejudices can kill...and suspicion can destroy...and a thoughtless, frightened search for a scapegoat has a fallout all of its own – for the children and the children yet unborn. And the pity of it is that these things cannot be confined to the Twilight Zone."
