Science may have had little use for it, but what was accomplished in terms of international cooperation is really quite impressive.
Maybe so. The point, however, is that this sort of thing could have been accomplished just as well by spending the same amount of money on any comparably complex international project - preferably one that, unlike the ISS, had some actual value, be it scientific, ecologic, humanitarian, whatever.
Amazing things could have been done with this kind of money and international cooperation. Instead we got a white elephant in orbit, proving nothing so much as our ability to throw good money (ISS) after bad (Shuttle) into the pockets of the aerospace-military-industrial complex.
Somebody please rewind the last 30 years of the US manned space program. It's been far worse in terms of fizzle-per-gigabuck than anyone's worst nightmares could have envisioned in 1979. It makes me weep.
