From what I have learned from sources is that by 2025 the Russian would have gone through their stockpiles of military equipment from the cold War
And they are likely not going to have the ability to replace equipment lost in the war
I do believe that the Ukraine's should be given aid to help them in their fight in terms of military equipment and other aid
I do think their is the possibility that Eastern Ukraine and Weastern Ukraine could be partitioned like Korea at the end of the Korean War
We just got to wait and see what happens
