I don’t really think Russians were to take Kyiv at all. It all looked like a threatening operation which could have been effective if the Istanbul agreement were signed.
They are not fools, and taking Kyiv is an impossible task with the limited allocated resources for this campaign.
Besides that Russians clearly understand that they will succeed only in Russian-speaking regions, which they actually did.
Assuming Russians were running an occupation campaign in the first phase is very wrong. They did not put any own city administration anywhere, left big gaps and gray areas and did not fortify their positions.
It’s also good to ask yourself, why Russians never bombed government buildings (while they managed to successfully bomb pretty much everything in Kyiv). And more importantly: why Belarusian pocket army never took part, though being ready on the border. My guess is that if it were an occupation campaign in the first phase, Belarusians would start clearing cities on the back of Russians.
There are more questions, than answers, but it’s fairly clear that once Russians pass the fortified (in the last 8 years) Donetsk region, they will be able to move much faster. However I don’t think they will - there’s not much interest in occupying territories with no coal or gas, and with hostile population.
I am accepting bets, that once Kramatorsk story is over, they will take Odessa region, and will try to take Kharkiv.
The military support west is providing will not win this war. Like with artillery and tanks - you can have weapons, but teaching properly artillerists and tank teams takes half a year at least.
It’s not me being pro-Russian, but trying not to underestimate the enemy and not to take him as a fool. It’s a good practise to be overly pessimistic and assume worst-case scenarios. Especially considering that in the second phase not a single city was retaken by Ukrainians, but only lost
