There's just so much we don't know about the current situation, but I think this is an overall plus for Ukraine and a minus for Putin's invasion.
First off, it "seems" clear that the Wagner group will be mostly disbanded. I don't see how they integrate into the Russian military. This is bad for Russia and good for Ukraine.
Secondly, the emperor's clothes are starting to show some transparency. The Kremlin drone episode was embarrassing for Putin, but this is a much, much more serious kick in the teeth and the response of the "strong man" Putin; reportedly leaving Moscow when contrasted with Zelensky's comment that he needed guns and not a ticket is a very, very poor look. It gives us much more of an idea about who and who doesn't have fortitude and belief in their cause.
Finally, if I'm part of the intelligence community, I am ALL OVER how to exploit this. There has got to be a TON of information going back and forth, troop movements, etc. I've got dollars to dimes that says US and other NATO intelligence agencies are mining everything they can to give Ukraine every advantage possible in this moment of upheaval.
The real shame is that we didn't move faster in getting Ukraine the kind of advanced weaponry they needed to fully take advantage of this situation. I know it's Monday morning quarterbacking, but the horns have been blaring for quite some time that the Biden administration, however supportive they've been....and they have been, moved too slow in providing the offensive capabilities Ukraine really needed to win this war. These kinds of supply chains and training take time and now we know a real opportunity was missed.
