Russia may not have

Russia is NOT the only problem, they aren't even the main problem. There's quite a number of issues where the mainstream media discourse depends almost entirely on whose in office. As an example take a look at crime statistics since 1991 and then align the media coverage about crime with whose in charge at the time. Immigration is another one. 2,000 people or more crossing the border every day may or may not be a crisis depending on which political party is in charge.

Those and other issues aren't being manipulated, at least not primarily, by Russia Propaganda. That work is being done by mainstream media sources and the only way to know you're being manipulated into an opinion is by putting in the work to learn the context and history of an issue.

It's a massive time suck that can require hours, days, or even weeks to get a deep enough understanding to know you're being lied to and / or manipulated.
