Japan was a full blown enemy of the USA. 
Russians were allies with US in WW1 and only thing they did to piss off America was invade finland which they got kicked out of the league of nations for and then by 1942 they were Allies again. The USA then rolled the Soviets into the lend-lease agreement they had with Britain. American propoganda made russians out to be based and good ol' papa stalin to be a great ally. That's why churchill had to make the iron curtain speech to warn people that it's time to flip the narrative. 
It's always completely uneducated people like you going around spreading conspiracies like it's fact.
