The USSR, at the official level, was never free of animosity towards us. Just a few things from what I'm studying right now, plus one big one:
They didn't shut down the Comintern, their official organization for subverting and destroying us, until 2 years minus about 5 weeks after Operation Barbarossa (the Nazi invasion), while we (the US) started supplying them with equipment on credit ~3 months after (for gold and minerals before, while the first arrangement was hammered out).
They refused to supply us with meteorological info, which seriously hindered our campaign against Japan.
They seized all the B-29s that were forced to land on their territory (was later copied as the Tupolev Tu-4); while this was consistent with their need to maintain their neutrality towards Japan after some engagements in Manchuria (where they owned the Japanese, but they really needed those troops; Georgy Zhukov earned his spurs and vital experience there), holding the crews was not, I think. They were "allowed to escape into American-occupied Iran" per Wikipedia and e.g. Tillman's Whirlwind: The Air War Against Japan, 1942-1945 (http://www.amazon.com/Whirlwind-The-Against-Japan-1942-1945/...).
This of course says absolutely nothing about how the two peoples felt about each other, and our mutual gratitude for what the other did in terminating Nazi Germany with extreme prejudice.
