Plenty of things are basically propaganda from both sides these days (Ukraine war),
but the latest on the internets is Prigozhi essentially calling out the MOD. Now, this video, assuming the translation is correct, would actually seem to point to western narratives being true[1], especially those about the Russian elites fighting and squabbling among themselves. A wayward general (or equivalent) successful of a major battle is certainly something to worry about, I would think. Hell, I've thought it for the Ukrainian side as well. We'll see, I suppose. But one should note that many of his most recent words have, by all accounts, pointed to an actual fissure among Putin's circle. [2]
Edit: well that escalated then deescalated really fast. suppose the main theories are: This was a real fissure in Russia. Prigozhin was speaking to the hardline faction's views that Putin was not going hard enough in this war. This would not align with some things Prigozhin said, such as Russia hasn't scored major strikes vs Leopard tanks and has had much higher losses than claimed. That doesn't seem to line up with a stated objective of fight this war much harder and right now. (note that some also claim that he is just nuts)
