When it comes to the internet, it seems to me that "the other parties" here carries a lot of weight when it comes to disinfo, polarizing propaganda, etc.
Why, do you think that the US, where all the giant social network companies are based, isn't doing this on a massive scale, much larger than anything Russia or Iran (and probably China for now) could ever hope to do?
Because most propaganda I see online seems to have a clear direction, and because of some not-so-recent "scandals" where a bunch of American influencers/grifters were discovered to be paid by russia to incite civil war.
Because if it did, we'd know about it. If we can get researches from Russia to expose their country's nefarious dealings, at the threat of death, we could easily get French, or German, or Canadian, or British, or American, or Czech researchers or whistleblowers exposing American propaganda campaigns.
Hell, look at Twitter/X. It got acquired by a mental guy who was screaming about government propaganda and censorship (while doing Nazi salutes). Do you really think that if there was any government mandate to do anything like what the Russians are doing, he wouldn't have exposed it as "SEE, I TOLD YOU BIG GUBIMNT BAD!!" ?
