Russia would have definitely fallen if not for the USA. It took 4 million Russian lives and 400,000 German lives for Russia to push into Berlin. Imagine how it would have went if the Russians had met the entirety of the German military, who MOST of which were defending from the Americans, Canadians, and the liberated French who were suffering minimal losses. Russia's involvement has helpful, yet not the deal clincher. Also, not to mention the poor polish army who were exploited to help Russia push through the Germans and the 45 years of occupation afterwards. sure they didn't have to speak German, they had to speak RUSSIAN!
EDIT: the pacific war was won almost entirely by USA, Canada, and UK. The allies saved Russia from Japanese forces
The vast majority of the german forces were involved in the invasion of russia, it was the largest invasion in the history of the world. The russians defeated it by themselves, most of the major victories having taken place before D-Day. It's not to say any nations involvement was not needed, without any one of the allies the whole thing could have gone very sour, but if Hitler had not decided to invade russia and had gone on with his original plan to invade Britain before declaring war on russia, then there would have been no preperation area for D day, no staging area, nothing.
The allies didnt save russia from the japanese forces either, the soviet union and japan had a pact saying they would not attack each other, this was only ended with the potsdam agreement in 1945 when the soviet union declared war on japan (after the war in europe had finished)
