If the Wagner Group had attempted a coup, it probably would have succeeded. https://www.rt.com/russia/595507-ex-wagner-fighters-join-chechen-unit/

What actually happened is that a small contingent from the group held a march on Moscow to protest the senseless casualties of fighting a war with both hands tied. Prigozhin wanted to get the war with Ukraine over with, not drag it on endlessly and needlessly.

A protest is not a mutiny. The Russian military, jealous of the Wagner Group wanted Prigozhin's warriors brought under their control. They used the protest to alarm Putin about a mutiny. Putin, who is unable to admit that his "limited military operation" is a blunder, came down hard on Prigozhin. The military got what they wanted. Prigozhin died in a mysterious plane crash, and the Wagner Group was dispersed among Russian military units, thus breaking up the best fighting force Russia had.

I have also noticed that RT and Sputnik support US official narratives, such as the "Jan 6 Insurrection." The explanation for this could be self-censorship by the English language Russian media so that they are not banned from the US.

If you think about it, the question arises: Do people anywhere in the Western world have a factual understanding of any important event? The assassination of President John F. Kennedy? The Gulf of Tonkin? The 1964 Civil Rights Act? The Soviet collapse? 9/11? Saddam Hussein's "weapons of mass destruction"? The overthrow and murder of Libyan leader Muammar Gaddafi? The Maidan Revolution? The Ukrainian-Russian conflict? The Israeli genocide of Palestine? The 2020 US presidential election? The charges against Trump?
