The troll factory’s original purpose, starting in 2014, seems to have been to shape the thinking of ordinary Russian, by viciously attacking domestic opposition activists and fueling public hostility towards Ukraine – and towards the United States.
Now that its secret internet project has been exposed, the troll factory will apparently focus more on open information warfare. Kremlin propaganda mills masquerading as news agencies will try to insert anti-American propaganda into U.S. – and Russian – media.
Given the rising tensions between Moscow and Washington, I think the domestic trolling operation holds more potential threat to America – than any (over-hyped) efforts to subvert U.S. democracy. It promotes Kremlin efforts to convince Russians that the United States wants to destroy their country and start WWIII (enhancing similar messages on state-controlled TV).
