So, Prighozin got pissed off with the incompetent military commanders and gobbed off, telling the world the real reason that they invaded Ukraine. Russia, in retaliation, decided to turn on him and take him out, but failed and now the Wagner Group, who will have plenty of sympathy from the Russian fighters due to the way they had been led, have turned on the head of the Russian Defence, including those very rich people who control them.
Not many would have seen this coming, including a Putin.
