You might be partially right, Russian military bloggers state this version too. Like there were tons of money invested into bribing Ukrainian political forces but it was stolen on both sides. However, right before retreat Russians were not in a disasterous state at the borders of Kyiv. In fact they were slowly closing the circle around it. If the focus were there, and additional forces were applied, it could have succeeded. Russians had heavy losses during deployments, but once positions were taken it all stabilised for them, so it was not as disasterous as many say. It was not that Ukrainian forces pushed Russians back, but more like Russians regrouped. From what I see in the last weeks, Ukrainian artillery is not capable of achieving goals. It could have been different before, but now a lot of videos from Ukrainian brigades depict that artillery support is missing and they go to battles without any support.
