Russia has messaging for useful idiots on the right and messaging for useful idiots on the left. To the right they'll say stuff like "America should stay out of foreign wars", "we should make Ukraine pay for the assistance", "the price of oil will go up" blah blah. To the left it's shit like "Ukraine are Nazis", "America is perpetuating this war", "NATO are the aggressors" blah blah
The goal either way is to sow division, doubt, demoralise, create instability, create distrust and sap European & US power's resolve to support Ukraine. And also to devalue information with false, misleading and contradictory information. It's not hard on social media to see how this shit spreads around with insincere actors pumping false news and misinfo into the feeds that gets picked up by the useful idiots.
