Basically, Putin has lost control over a part of Russian territory.
Personally, I was very entertained. I'm not sure that the poor inhabitants of those border villages necessarily shared in my excitement, or if the Kremlin was very pleased - but I certainly was.
Here I am, sitting and waiting for a big Ukrainian counter-offensive. Then, Ukraine loses control of "impregnable fortress" Bakhmut but denies this fact for nearly a week. At the conclusion of this week they make a bold and daring raid into Russia proper. Complete with troll memes like:
1) MRAPs can be bought in any store
2) The Belgorod People's Republic demands independence
3) We must conduct a referendum to establish the people's will.
Don't get me wrong. It's very funny, and an artful way of poking at Russian hypocrisy. But one cannot escape the feeling that Ukrainian command is motivated first and foremost by headlines, rather than any military rational. Within 48 hrs most of their contingent of traitor Russians and UKR special forces were wasted. The move caused consternation in Washington, which simply reiterated "that they received assurance from the Ukrainians that American weapons will not be used in Russian territory".
Ukrainian trolling is getting better, but their strategic situation seems as bad as ever.
