What steps could Germany feasibly take to obliterate/defeat/overpower or force a favourable peace with the USSR, just in a 1941 Blitzkrieg offensive? Could they possibly reach further, or what imcompetances on Russia's part could result in victory (for example, if they allowed more of there men to be captured killed). Extra points for explaining how Germany could capture the Caucasus and cut off oil or Moscow (how feasible these are in real life); and also how could this cause a collapse of the USSRs economy. Thanks for your time.
