content: Attacking the Soviet Union may have been the right move.  Germany had very limited resources, especially oil (just 1% of the world's total) while SU had high oil reserves and production. WWII Germany had 0 chance of winning a war of attrition which is what would have happened had they simply waited.    By attacking he brought the SU to the brink of defeat.  The only reason it didn't fall was because Hitler suddenly changed his mind about sending his army to Baku and send it to Stalingrad instead.
