This is a point that doesn't get enough emphasis. The entire Russian system, such as it is, is complete trash with no checks and balances on anyone other than the jockeying to be Putin's biggest ass kisser. Sycophants to Putin hold crucial positions everywhere through their personal loyalty to him, not because they have any ability to do their jobs well. These people are hugely corrupt, siphoning much of the money off and leaving their armed forces and industry operating with cheap, broken down equipment, made up lists of supplies that don't actually exist, etc.  


There are plenty of military reasons why they've failed, and some of them are also tied to the same complete lack of meritocracy anywhere in the country, but it's the abject corruption of their government and military officials that made this fiasco possible. And even now, no one will speak the truth, so here we are with them just murdering civilians daily for no military reasons at all because they won't recognize that this is already over for them, but have no way to "win" the war without just razing Ukraine to the ground.

I firmly believe that the most consequential 30 seconds of 2022 was Zelensky’s midnight address to Ukraine from the streets of Kyiv along with the senior core of the military the night after Russia invaded. The statement that their leadership was staying rather than running was, IMO, of monumental importance to this conflict.
