Ok, let me say this :

The design for the ISS is not junk, in fact it could have become one of the greatest scientific creations and the most wonderful space construction projects of all time, it could have produced even better results than MIR or Skylab. The whole international thing was badly managed and now we don't even have a half-finished station, it could be becoming a junk project fast but since the loss of Shuttle Columbia over Texas the whole thing has got even more complicated. The Russians with their Soyuz and Progress is what is keeping the United States in space right now. The Shuttle ( STS which may cost double the price of the ISS before it retires ) should return to flight soon but it has too much work lost, so I doubt it will ever be able to finish-off the station.
