No matter how hard Putin is trying to shape the narrative, most young russians do know this is Russia invading a sovereign state. If you dont share Putins imperial dreams, you are not going to commit in this fight. There is no way this 4:1 population ratio is going to materialize as an advantage on ukrainian territory, unless Russia is going to draft all the +60 year old talking heads.Russia has 4 times the population as Ukraine but more importantly Russia has much more natural resources and much more industrial base than Ukraine. I can see Ukraine being successful on the defensive but if Ukraine goes on the offensive then I can see Ukraine lose a lot for no gain.
