>Almost everything about the way that Russian information operations (IO) or information war (IW) operates is public record; there are even public handbooks explaining it for NATO analysts. Russia aims to effect a heightened state of chaos in target countries, turning citizens into chaos agents and thus unwitting aides to Russian subversion. Unlike any other example in recorded history, Russian IO has so effectively pervaded our culture that it has essentially integrated with the media arm of the Republican party; Russian pro-Trump narratives are basically indistinguishable from Republican ones.
>This joint effort has successfully persuaded the most rural, most-impoverished, least-educated Americans to elect the most wildly unqualified, serially adulterous and thoroughly compromised President in American history.

And as we have seen in Alabama, this massive international effort is undertaken in ongoing cooperation with the Republican Party.
