I see the FBI has indicted some Russian individuals and organizations for spreading disinformation via social media during the 2016 election. given the likelihood of ever getting their hands on the perpetrators, it seems to be pretty much a pro forma exercise aimed at showing some results for the Mueller team.
I can't say I'm particularly shocked. They've been doing that sort of thing since New York Times readers lapped up John Reed's piffle about Lenin's socialist paradise. There has been a proud tradition of trying to influence US affairs since the Citizen Genet affair. And who could forget the endearing clueslessness of the Guardian enlisting Britons to try pushing Ohio voters into the Gore column?
I'm not exactly sure what the Russians were trying to accomplish. Revenge on Mrs. Clinton for her remarks about their election. General purpose mischief? Fellow-feeling for Mr. Trump? Personally, I think they wasted their money. We are more than capable of generating sufficient codswallop domestically.
