Did you forget that Zelensky and Budanov were saying that they will conquer Crimea soon? or maybe when Blinken said that the Russian army is the second best in Ukraine? There are a lot of examples of high officials who made it look like Ukraine is winning or is going to win, they tried to create a momentum with lies when it was clear that Ukraine stand no chance in this offensive, maybe if they prepared for a longer time and improved their airforce they would stand a chance but they were pushed too early into this. What we see now is an unstoppable Russia completely unharmed from sanctions and with great production rates. Ukraine was used as a pawn to cause some damage and then be discarded, the west didn't want it to win this. These men were sacrificed as tools, I would feel very insulted if I was an Ukrainian. The "combined arms" strategy was also a lie because this requires an Airforce and Ukraine is lacking there.
There are some local news sites (on my country but I guess on other countries too) that were writing lots of stuff and analysis but it looked trollish, keep in mind many news sites invested into this, (pro-russia propaganda), these will end up being winners because if Russia ends up winning, they will now look credible.
