Actually, the US didn't have much choice about it, since the Saturn V obviously didn't live up to specifications (otherwise they would have used it).

Um. It was already used for other launches. In what way could it not have met specifications, making it unsuitable for the ISS but suitable for moon missions and Skylab?

If it was unsuitable for something it wasn't intended for, couldn't that be because its specifications weren't written for that purpose?
