Apparently you are in an information bubble, captivated by delusions and an abundance of fakes.
Funny coming from a Kremlin copy-pasta troll.
Russian troops are acting primarily for reasons of expediency. Activity in the northern direction played a role in the initial phase of the operation. To storm a city of three million with a limited contingent of forces is madness.
So why did they attempt to do it in such a suicidal way? Rhetorical question but if you need to meet today's quota - feel free.
