About the WW2 thing... you sure?
If it hadn't been for a few little things, namely some Hitler's political ideals, Russia would have been fighting on Germany's side.
And even better, they were communists as well, something America was eventaully fighting in Vietnam. Remember, Russia wasn't allowed a say in the Treaty of Versailles. I doubt they would have fought alongside America in any case...
If you were just referring to the general idea of sides, then yeah, I agree.
I've done History. ;D
You're probably right though, because I'm always wrong...
