You keep banging on about these leaked US military papers like some kind of weird mantra. These documents started to be released in early January 2023. They contained a lot of stuff about Ukraine, Iran, Russia, China etc….
The stuff that was pertinent to the Russia / Ukraine war (the point you keep making) related to supposed US analysis of the war in the Donbas region only.
It stated that the US could only see a stalemate in that region as the outcome. The assessment was made based on manpower, heavy armour, training, intel, tactics and available arty capabilities at the time (early 2023).
You have to be mindful that the war is being waged in a far wider scope than just the Donbas region (Luhansk, Donetsk oblasts). The war now includes Zaporizhia, Karkhiv, Kherson and Sumi oblasts. Also many things have changed in the Ukrainian Military since the reports were leaked. New tactics, new military leadership, new weapons and ammunition finally provided by the US and a relaxation of the rules of engagement allowing Ukraine to attack muster points and strategic targets inside Russia.
At this time no-one is winning the war but one thing is known for certain and that is Russian’s are dieing in their thousands every day. I don’t care how many Putin mobilises -they just go to the front and end up getting slotted. Putin recruits 30000 a month just to backfill his losses - Something will eventually break given these casualty rates.
Ukraine will keep on fighting - they and only they, will decide when it’s time to negotiate.
Have many potatoes for your valuable counterbalancing contributions comrade.
