I agree with this for the most part. This ukrainian offensive must be some surprising and brilliant stuff if it is to be successful.
However with one caveat: the Russian bum rushes (and huge losses of vehicles) that accompanied the first months of the war looked to me more as a way to gain ground as much ground as possible despite not having infantry. The results were disappointing but they still secured most of the prime real estate. They sacrificed armored vehicles to gain what they could otherwise not achieve with the careful application of combined arms and unit preservation.
I don't think a single anti-russian biased commentator has thought or even considered speaking this out.
The data will not be known for decades.
But I think there were two operations at the same time with a clear objective and one in between in the first months of the war.
In my opinion:
1 - Quick political victory:
Quick decapitation attack on Kiev, around 40.000 troops, this is the same as Wagner used in Bakhmut, Kiev is a city of 3 million inhabitants even more in its metropolitan area, so the objective of this was clearly political.
The casualties here were not catastrophic but in bain, a risky manoeuvre trying to replicate the success in Kazakhstan, brought Ukraine to the negotiating table but strong Western support and internal purges, such as the SBU's assassination of the economy minister, which favoured peace negotiations made this impossible.
Seeing this avenue exhausted, they left.
2 - Pure military operation.
Attack to secure the Russia - Crimea land corridor, this was a complete success, casualties do not appear to have been heavy, major cities such as Melitopol fell on the fly without a fight with the AFU fleeing, major AFU ammunition depots were taken, the largest nuclear power station in Europe ...
3 - Mixed group.
This is the whole "northern" area, here there was confusion, disorder and casualties were horrendous, cities that were surrounded and could have been taken like Sumy were simply not taken, columns were thrown into the dark woods to try to get to Kiev fast while half-heartedly trying to take some cities ...
This is where Russia's worst casualties were concentrated as the brigade of Arctic troops.
In my opinion, there was A and B planning, it was a sensible plan for the most part, but everything about the "northern" group was just plain stupid, with unclear objectives.
