This is the state of the way things are. Date on the video is November 2, 2025.
It's bad.
As far as Russia taking so long to finish it. There is another side of the coin, NATO taking so long to supply this circus. Weapons, mercenaries, advisors. The very moment Russia finishes things in scenario you are thinking, that is the moment Ukraine becomes NATO. The basic idea is to prevent that. Russia is not in the hurry.
That said, situation dictates collapse of Ukrainian war machine, similar to operation Overlord and Barbarossa.
It is already collapsing.
