This is funny, but mostly sad.
The goals of manned space exploration have been the major (non-military) driving forces behind the space programs - which has fortunately resulted in many tech advances, including the continuing unmanned studies of our solar system (and beyond).
Weapons delivery tech is not NASA (history does not end in the 60's). Granted the military (due to funding and national safety) has driven many things - including the shuttle program (which I don't like, but that's another issue). But, this is mostly surviellance - deployment and maintenance of very expensive U.S. investments.
And to say that MANNED spaceflight hasn't resulted in much tech or research is doneright silly - there has been a great deal of research done and it has resulted in a good bit of spin-off technology (not to say this was the best investment in resources). Have a look at
NASA Tech Briefs.. and for a simplistic view see
here. (I was looking for the NASA Spin-offs mag, but that might have been an internal only thing from a long time ago)
As for more jobs - NASA employs a lot of Americans directly and indirectly. (Most NASA 'employees' are not on the federal books as they are paid via a third party even though they work at NASA facilities).
For our space bucks we get pure research, spin-off technologies, jobs for skilled and educated people actually producing things (other than commercials), a applied research infrastucture, direct support of the sciences in major academic institutions - and these are American Jobs and largely stay American bucks!
As for international cooperation - yes each entity builds its own modules , though there is still a tremendous amount of engineering interaction (power systems for one, plus life support and interconnects). Accommodating the space shuttle is
not a major design requirement - the 'designed' lifetime of the ISS is ~2015, but the shuttles are scheduled for retirement next year (not that both aren't likely to change). The Russian space vehicles provide the majority of flights, though the Space Shuttles' (Canadian built) Remote Manipulator Arm was an invaluable tool till other arms where installed, not to mention the benefits of the cargo hold with its large bay doors (a U.S. military requirement that had side benifits).
Is the space program expensive - especially the manned part - Yes! Is it wastefull - most definitely. Is manned verus unmanned space 'exploration' wastefull - Certainly! But if you look into the facts - most of the 'waste' is due to politics - and largely that is a matter of jobs for constituents and lining pockets of big business. And lets face it most of our elected 'representatives' aren't qualified to balance a checkbook - much less understand the benifits of unmanned versus manned space exploration.
BTW: I personnally don't stay abreast much about the space shuttle, ISS (just tell me when it's gonna come burning down), or other manned lunar or mars mission chatter - I'm much more interested in scientific unmanned missions - which is easier since my father fabs and installs parts on a fair number of the NASA and ESA missions
