Sorry if I'm not keeping up. My big worry now is Wagner being genuinely annoyed at military tactics, shaming Russia as a weak force, and eventually returning to the front line with full backing (to save Putin's political face) and tactical nukes. I think Prigozhin is probably smarter than that, knowing it's a red line (we say!) but an unstable Russia might make NATO even more cautious than it's already been. So it might give him an opportunity to stabilise the current land grab and come out a "hero".
I want to enjoy what's going on, but it's making me really nervous. It is, however, better than them all working together effectively and smashing under-resourced Ukrainian forces. That I'm temporarily happy with!
