Zelensky clearly can't stand any officer in his HQ to be more competent than Sprechstallmeister-at-Arms himself, and this is quite a low ceiling. Kursk incursion, aimed at pullback of Russian forces from Southern Donbass axis, fizzled spectacularly because of this very feature of his personality, which Russians seem to have already learnt, and another one, namely, that Zelensky acts like a ratchet in all his strategic decisions.

Recall that it was Kharkov region where one of two main successful counteroffensives of the UAF took place, and later, during last spring, Russian attempt at encircling Kharkov failed in a manner so grotesque that the entire flank of their Northern operational command still, half a year later, is slowly bulldozing through the ruins of pretty small town called Volchansk near the border:

Zelensky faces a fair and direct choice: 1) elections, graceful exit, and salvage of what was left of Ukraine, or 2) debellation and collapse of Ukraine, possibly in slow motion, but irreversible all the same. Judging from his actions, he choose the path trodden back then in Athens when Alcibiades had been expelled, or six out of eight strategoi executed after the victory at Arginusae.
