Well, the land in Kursk has been x100 easier to take for Ukraine. Do I need to explain that the losses were minimal, the number of soldiers captured large, that there are more than 1000 km2 taken in a couple of weeks? And make no mistake, Ukraine is very active there still, but the command is just not publishing anything at all.
It has taken thousands of dead soldiers, 11 months and innumerable resources for Ruzzia to take a similar chunk of Donbas. I am not ignoring that Ruzzia got land in there - shattered, mined and ruined land - I am just saying that Ukraine took, and is still taking, a chunk of Kurst at much less cost. You do not get points for effort on this, if you want Kursk back, then you will have to keep the war going for another year and hope your economy and society holds or... give back part of what you took.
The Ukrainian Armed Forces operation in Kursk Oblast was very well organized and is an undoubted tactical success for Ukraine. But strategically, it is a failure. After several days of rapid advancement, the front line stabilized, and now what? I think Syrsky will soon be fired, as the commander-in-chief of the Ukrainian Air Force was recently fired after the F16 was defeated by friendly fire.
