Washington demonises Russia, conducts aggressive military maneuvers in Russia’s sphere of influence and rejects Russia’s president depicting him as “the new Hitler”.
The recent decision by Facebook to label as “state media” certain Russian, Chinese and Iranian outlets is an anachronistic propaganda tool which resembles Cold war tactics. Facebook labelled, among others, as state media Russia Today (RT) and Sputnik from Russia, Xinhua from China and Press TV from Iran. This move comes a few months before the next US presidential elections and some in the United States want to rejuvenate the conspiracy theory that Russia or some other foreign country meddled and influenced the results of the previous elections in 2016.
This is part of the pro-Kremlin's media's ongoing efforts to deny Russian meddling in the 2016 US presidential election.
Facebook recently published a statement on the reasons for labeling state-controlled media that are wholly or partially under the editorial control of their government. This is not an "anachronistic propapanda tool" but a transparent, thorough exercise in which Facebook sought advice from experts in various fields. Indeed, Facebook has initiated an effort over the last few months to enhance its integrity profile ahead of the next US presidential elections in November 2020.
There is extensive evidence and research demonstrating Russia's influence operations around the 2016 US presidential election, including exploiting Facebook to post ads and influence voters' preferences (see here, here and here).
The US intelligence community had evidence since 2016 about Russia's activities to meddle in the elections, and the most thorough examination of these efforts is the Mueller report.. Moscow's efforts to interfere in elections in other countries is also widely documented.
