After much reading and review I have come to the conclusion that there has never been a true national space policy since NSC 5520. What forces are in play in developing a national space policy? Description and Why they are contributing factors to space policy?

Government (Executive administration, NASA, DOD, politicians)?
Space Industry (Contractors, Private Business)?
Space Cadets (Scientists, Engineers, Space Enthusiasts, Average Citizens)?
