I’m no general so of course I have an opinion that means nothing. The analyses I’ve read also suggest the same thing - but caution that Russia already has a huge manpower advantage. If they can more effectively fight on two fronts than Ukraine then in a little while I worry that we’ll see these Ukrainian soldiers isolated and cut off, encircled, and captured or killed. Then Ukraine is worse off than they started unless the gains they make in the east while Russia is distracted are immense and war-ending.
