The peculiar paralysis of Russian services in the face of the "rebellion" of Prigozhina

The "Rebellion" of the Prigazine ended before it started for good. Furthermore, both the FSB and the Russian army's consequence to the crisis was at least peculiar. Wagnerovists marching towards Moscow have encountered almost no resistance. Putin seems to have left a good face to play. The most crucial thing from the position of Polish security, however, is what will be done by Wagner Group mercenaries, who were to arrive in Belarus for thousands. Will it actually be training Belarusian units or making "problems" at the border?
