honestly you dont sound as smart as you yourself think you might
just as a beforehand, do i think ussr/russia should receive those vehicles? no
but matter of fact those captured / leased vehicles were in active service in the USSR and they have a history with them as well and belong to their own history.
They do in fact have a right to ask for it. Even if they shouldnt necesarily get them.
Same about the ukraine matter, ukraine should never be added Russia. Problem is that the tree in reality is called USSR not russia and ukraine was part of the ussr.
Strictly speaken ukraine is part of the ussr tree
