greatest threat to Germany
He felt that the weakness of the Red Army created
the best possible opportunity to eliminate this threat

25. Soviet Losses
The Soviet war effort was so overwhelming that
impartial historians of the future are unlikely to rate
the British and American contribution to the European
theatre as much more than a sound supporting role.
