The suddenness w/ which Prigozhin is being vilified/erased by the same groups (botnets, news media, TV pundits) that once lauded or at least tolerated him shows you how easily the Kremlin could end the invasion & sell it to the public, if it wished.

Admittedly, Prigozhin was never a star of state television, but the capture of Bakhmut was a genuinely celebrated moment in state propaganda.

Call off the invasion, offering whatever excuse you like for why it was a massive victory for Russia, and the detractors would only be able to moan on their Telegram channels.
