Czarist Russia was never an American ally (Only a circumstantial one in WWI!) but we always had a cordial relationship with them. There is no reason we can return to a similar state of affairs.
I'm assuming you actually meant "......no reason we can't return.....".
If so, I agree completely. Americans and Russians are far more alike than different (the only major countries in the world with a "frontier" tradition, although Australia might also qualify). And we both have far more to fear from Muslim culture than from each other.
