yeah, if germany never attacked russia, england woulda fell, hitler just didnt have the patience to wait england out and had 2 use all his pretty toys and the only target left for his tanks was russia. and germany still had a small chance to win even after they attacked russia, but lets face it, hitler wasnt a general and he made mistakes that say, rommel or other generals wouldnt have made.
Its not that easy, Germany did not have the Oil, Raw Materials, and Food Stuffs to sustain itself for a long war. Russia had sufficent quantities of all 3. Germany invaded Russia when it did cause of economic neccesity. Also, cause of the massive industrial/military advancements in the Soviet Union after the disaster in Finand, if Germany waited another year or 2, the Russian military would of been strong enough to handle Germany’s.
