Obviously in hindsight it was a bad idea to invade Russia and make them an enemy. From my understanding, Russia was supplying them raw material to fuel Germany's war machine. But Germany wanted those resources for themselves and invaded Russia. I wonder til this day if Germany had not turned on Russia, where would they be right now. Russia was the reason why Germany lost footing and turned back to Germany as the lost the battle of Stalingrad. Could they have continued to buy resources from Russia or found other means to resupply themselves?
