Battle of Stalingrad absolutely decimated the german soldiers. It was after this point that the Red Army started advancing on and eventually taking Germany. A lot of people say that America won the war and downplay what Britain, Russia, Norway, Turkey, Poland, Australia, Canada, Belgium, France, the Netherlands, Greece, New Zealand, China, and French Indochina (now Vietnam) (yes they were all on the allied side) did during the war (acting as if America fought the whole war by itself, which always pissed me off), but if you were to say that one country won the war, it would be Soviet Russia, where Red Army is decimated by YOU! Oh, and I have looked at the history and think that if Hitler had waited to attack Russia, then he could have won the war. And no, this is NOT Godwins law because this is actually relevant.
