You are correct in my opinion. It seems whoever orchestrated that thought it would be the second Crimea, forgot Ukraine had 8 years to prepare (even with a shared soviet corruption problems and cheap traitors) and completely ignored the historical case of their resistance in and post WW2. One magazine even published a postponned article summarizing the achievements of russian warriors, and there were public persons speculating about taking Kiyv in three days. Even if you ignore them normalizing of such an act at all, they were sniffing their farts while planning it and thinking it’d go alright.
