Oh wow! I had to look up in DuckDuckGo about Kursk; and Ukraine has indeed invaded the Russian territory proper! I thought the initial incursions were done by Ukrainian-backed anti-Kremlin Russians again, but it’s actually the Ukrainians! This actually answers the question that had been hovering in my head for the past couple of days of whether or not Ukraine could mount yet another offensive.
You may make fun of it, but the reality of it is even funnier: Ukrainian army is probably occupying gas and oil distribution hub for Hungary, Slovakia and partially for Turkey.
So now Putler has few bad options:
Try to liberate it which would probably mean destroying it (using usual Russian tactics).
Do nothing and look bad in Russia.
Make some concessions to UA and look bad in Russia.
