Well, the russians COULD lose the war without the allies, but they were supporting them first with leand-lease thing and then, with bombing factories and other shit, but invasion was completly useless, russians were already in Poland + allies had troops in Italy, maybe crossing Alps were too difficult..

*was

please do show me how wrong I am, the russians were the first to reach into Berlin, when the Americans and British got into Berlin it was mostly cleared by Russians, Stalin won World War II by himself (and vodka)

I'm guessing, among other things, you're forgetting the ENTIRE PACIFIC THEATRE.

nah, they kept forward, even though lots and lots of them died (D-day for example, on the 3 beaches)

lol implying I'm a drop out like you, pfft, History books, son, my dad never told me shit about World War II
