Genuine question. No sarcasm. I respect you views.
Russia has already won because it holds all the cards.
Economy, military industry, manpower, corruption dealt with, they learned from their previous bad assumptions, and will now use Russian Army doctrine that will only advance under the umbrella of ISR and IADS. It will be a meat grinder, slow and sure.
Ukraine has no economy, will soon run out of ammunition, NATO and the US don’t have the military production capacity to make a difference. General officers are already talking about that.
In the simplest of terms, there is no path for Ukraine to win. Everyone is going to get a lesson on Clausewitz from their living rooms.
